Evaluation of circuit tree with a stm32f407 microcontroller board -Part2

Design Goal

Time for another test of capability. These tests help us check the hardware compiler performance to a actual built commercial board. Some of the items for us to check are:

  1. How closer are we able to design the board with respect to requirements?
  2. Is there any possibility of optimization among circuit tree outputs?
  3. What is the board cost compared to the comparison board?
  4. Circuit Tree designs would be different than the designed board. How do we verify the design?

Olimex board

This time we compare the capability of circuit tree with another commercial board in the market available from olimex. It is a great open source hardware board available at a competitive price with great support from olimex.

Let us again pick the requirement of the board from site :

  1. STM32F407ZGT6 microcontroller
  2. JTAG connector with ARM 2×10 pin layout for programming/debugging
  3. Ethernet 100Mbit
  4. UEXT connector (UEXT is a board to board connector which supports three serial communication interfaces – I2C, SPI and RS232. There is also 3.3V line and GND.)
  5. USB host
  6. USB OTG
  7. SD-card
  8. Input DC DC power supply which allows operation from 6-16VDC source
  9. Power and user LEDs
  10. Reset and user buttons
  11. 4 full 20-pin Ports with the external memory bus for add-on modules
  12. Arduino platform with unsoldered headers
  13. 4 rubber pads for the mount holes
  14. PCB: FR-4, 1.5 mm (0.062″), soldermask, silkscreen component print
  15. Dimensions: 101.6 x 86mm (4 x 3.4″)
  16. Boards costs 40USD in quantity of unit 1 as per olimex.

Requirement entry in Circuit Tree

Let us add this requirement on circuit tree requirement editor:

Step 1:

We add requirements in the tool by adding spi, i2c and other buses to a UEXT connector. Similarily for the Arduino connector the spi and uart bus signals are routed to the connectors. We additionally add the GPIO connector having close to 11 pins. Additional interfaces such as ethernet with lan8710, usb type AB port with esd protection, sd card and jtag ports are added as per the snapshots below.

Step 2:

Circuit Tree hardware compiler next finds the controller which can support these function. Circuit Tree returns close to 186 parts. We have option to select STM32F407ZGT6 or STM32F407ZET6 with several other parts. We choose STM32F407ZET6 as olimex schematic has this part designed into it.

Step3:

We next select power of 6V to 14V as required in the requirement and get the schematic design generated in a minutes time. You would notice that the BOM cost derived from Octopart comes to USD 51. The pdf, bom and eagle schematic design is available at link

Step5:

Output placement file is shown below with the constraint that all components be placed on the top side of the board. The red color denotes the placement of the component on the top side of the board. We need to work more on the board by adding the constraints to the board footprints. The arduino connectors are misplaced in the picture below. Files are uploaded at link

Differences

  1. Other differences:
    1. Power, clock and reset generation is different in circuit tree. It shows that circuit tree can generates it own power supply connections based on what it calculates the extremes.
    2. Some of BOM parts selected by circuit tree are high is cost. One of the examples being integrated magnetics which cost close to usd 10. We would address this concern once we have sufficient parts in the library which would provide value range to the user.
    3. Arduino connectors are not compared as the pin assignment and gpio connections are not as per connector requirements even though the muxing from controller is correct. In the next release we would have new feature to change the connector pin outs.
    4. IFC pin connections failed as circuit tree does not generate a connection where it observes conflict of IO’s. The commercial schematic uses jumpers to isolate segments which we can also support at a later date.
    5. The placement of the design was not the same as the olimex board. We are in process of improving the constraint addition which would  help to create more custom designs.

It was a long post with visual comparison of the two boards. Write back to us at info@circuit-tree.com with your feature requests and suggestions.

Another Experiment at circuit tree

We keep enjoy experimenting. Experimenting to create new type of designs, find issues, open new exciting features, check new ways to test the circuit Tree designs. We have a lot of capability to churn and mine new embedded designs using so many controllers, peripherals , placement options. So how do we check so many designs to check if they meet circuit tree quality goals?

Experiments at Circuit Tree

Experiments at Circuit Tree (Image Link: quote fancy)

Well answer lies with scripts. We use scripts written in python for several application including this one which auto generate controllers designs with random placement files. Even though regular users have menu options to choose designs scripts do following testing autonomously:

  1. select a processor/microcontroller
  2. Randomly choose peripherals that can be connected to it to generate design. The number of peripheral selected are random.
  3. Randomly select a voltage to be applied to the circuit
  4. Randomly select applied voltage options. It can be through custom voltage adapter or through the battery select options.
  5. Randomly select board file through dxf file and does auto placement of components. Only the files where the part placement is possible the file picture is taken and displayed.
  6. Test for errors
    1. Error between circuit tree designs and eda tool export options
    2. Check if the symbols and footprints are being exported correctly on the library.
    3. Check if all the cad design can be generated without issues.

Now we invite you to be the judge of the designs created with circuit tree. Check the github directory to see our design listing and let us know if you are able to find design errors. Then we would know if the experiment helped us.

Small Drone Design Prototype

We have chartered a new goal to create development boards of the designs created by circuit tree to showcase Circuit Tree Design capability. To keep the task fairly simple the development board requirements are listed below:
1. Create a drone board which can fly while being controlled from mobile bluetooth. The frame of the board would be a PCB where the Motors would mount.
2. The drone board should be powered by a battery and should have battery charging capability.
3. The Main elements of the drone board would be a small micro-controller, bluetooth radio, accelerometer, gyroscope, compass, jtag port for debug, 4 pwm’s, led and reset switch.
4. The battery of this board when in air should last for minimum 15 minutes.
5. As a first bringup goal the drone board should be able to fly till small altitude.

We start by estimating the weight of the drone board with battery to find if it can meet the goal no 4.  We analysed and decided to select the motors for the project listed below:
1. https://www.banggood.com/2-x-7mm-Hollow-Cup-Motor-For-Hubsan-H107L-Upgraded-Version-p-80923.html?p=OY2106728901201408U4
2. https://www.banggood.com/4X-Racerstar-615-6x15mm-59000RPM-Coreless-Motor-for-Eachine-E010-E010C-Blade-Inductrix-Tiny-Whoop-p-1115474.html?rmmds=detail-bottom-alsobought

Next we start the electronic design. We chose circuit tree design to first look at the list of controllers which can be used for the drone design. Based on the component avaibility results we narrowed down to stm32l052k6t6 from st micro electronics. Quickly the components were selected as shown below and a block diagram generated.

Board requirement catpure screen

Board requirement capture screen

Board block diagram of the components selected

Board block diagram of the components selected

We did wait for schematics to generate within 2.5 minutes and within that time did scan the Bill of material file generated from the tool. There are certain discrete components which circuit Tree could not select which is left to the designers to update.

Also in the schematic we have a dummy connector added for Timer pins. The connector is important as it helps in allocating the micro-controller pins for the Timer/PWM. The intent of using Timer is to allow mosfets to be added to these pins to eventually allow motors to be driven.

Next we click on the layout viewer to select a dxf file and check if the placement dxf outline is correct. Next we fire the background process to generate placement.

Board components prior to start of auto placement algorithm

Board components prior to start of auto placement algorithm

Within next 3 minutes the placement of the board is generated and it looks as shown below:

Finished Board component placement

Finished Board component placement

The algorithm shows that the components can be fit in the given board dxf file. It is time to define the board boundary restriction so that the algorithm can rerun and produce more symmetrical placement around 4 weeks.

We would keep updating the blog as we get the results.

Here is the Git hub link for design files for the drone design.


 

Update1: Sept 16th 2017

Muneeb started working on the eagle downloaded design to add motors pads and mosfets to the design.  He is one of smart engineers we have on circuit tree who took the design and first started to review the design and compare the output of circuit tree with the stm-cube tool output. Once we was happy with the output it was time to change the connector page to add the motors pads and mosfets as shown below. The only change he had to do in the downloaded eagle schematic file was to change the grid to default.

Here is the copy of the page he edited:

Updating dummy connector page with motors and mosfet.

Updating dummy connector page with motors pads and mosfet.

The next check for him was to check if the eagle ERC was displaying any errors. No errors were found but number of warnings were observed stating two similar named nets are connected to one another. After a check it was time to see if the the circuit tree board file can get newly added components(mosfets and motor pads) in the placement. He further customised the placement file to meet his requirement.

Update no 4: Oct 30th 2017:

Here are the set of assembled boards designed through circuit tree.   Board bringup’s are always interesting milestone for a hardware design engineer as we spark new life into a element.

Quick checks done so far:

  1. Component placement checked
  2. Power short check shows no issue so far.
  3. Weight of the board.
  4. Note there are no overlapping components.

So far so good. It is late in the evening will do the bringup tomorrow with a detailed test plan.

Update no 5: Nov 2nd 2017

Picture of the board assembled with motors and power test. Board was first tested for open short test. The board was powered with usb cable and then the main board voltage was found to be 3.29v. Great work so far.

Update no 6: Nov 4th 2017

The moment we have been all waiting for is here. Here is a quick update on the board bringup:

  1. Powered the board through the usb cable connected to a laptop. All voltages are good.
  2. Connected the st micro to ST-LINK/V2 through a custom adapter cable as the connector on the board was incompatible with the pitch of the programmer.
  3. Detected the stm32l052 device on the programmer console.
  4. Programmed a code to drive the motors through the mosfet.
  5. Next connected the battery on the board after switching on the board.
  6. Result is as shown in the video. The right side of the drone had more lift compared to left side.

Really happy and satisfied with the result.

The next steps would be to connect the board through bluetooth to power on and off the board using laptop bluetooth control. Also we would interface with all the board sensors to get the real time data.

The good news is that the most of the hardware functionality is working as expected. Circuit tree application has designed a board which is reliable in short span of design time. In hardware design lots of items have to tick right and circuit tree has just shown the capability.

The next update would be in few weeks when we have created the software.

 


 

Update no 7: Dec 10th 2017

Here is another update to the drone testing. In the video below you will notice that Bluetooth and a application layer is running on the drone which allows turn on and off of the left side and right side motors. You will also notice that we had to connect a wire on the board to connect the stmicro with the bluetooth transceiver. This wire was added to allow the software to reset the transceiver as needed. This is the option which would integrate in the application.

This is a good learning we have had. In the next update we would share the application software used for the development which would be free to use.

Thank you for reading through the long post.

Guide for creating Design from Scratch with circuit tree

Here is a guide for a new user as well as provide details to a user about the design flow.

Let us start with a example wherein you select a design suggested in our post. The post contains a am3352 processor from texas instrument and is fairly popular among engineers. In the example we create create design schematic for a olimex board.

Evaluation of circuit tree with olimex am3352 board

To start with, login to the site Circuit tree tool and you will enter at the requirement editor section.

A clear design requirements editor will have only Board Entry Power block on the editor area similar to shown in the figure below

1

On the left side from the library menu look for the Texas instrument Processor AM3352 then drag and drop the block to the editor area. Once block will be placed a Board Entry Power menu will be popped out similar to one shown in the screenshot. Select the connector, input voltage range and type of the power and press Save changes button.

To add NAND memory to your board look for the Parallel Memory  Library and place the block to the editor area. In Library Functions drop down menu select the NAND option and click Get Parts button. If the selected part is right click save changes button or click button represented by arrow in Select other Matching Parts.

22     23

Look for the 8GB NAND memory and then click the radio button to select the part and then click save changes button on both windows to go back to the editor area.

24 25

To add SD card support to your design place the SD Library to your design and choose from the SDHC connector, Micro SD Connector and emmc memory. Click the Get Parts and once application finished loading part click save changes button to go back to the editor area.

27 28

For debugging, CT also support debug connectors to be placed on the board. Place the JTAG library on the editor and select ARM 2X10 Connector or other from the library function options. Click get parts button and then click save changes button to finish placing JTAG connector and to transfer the control to the main editor.

30 31

Circuit tree also includes CAN transceivers for industrial and automotive designs. Place the CAN library from the library menu and click the Get parts button on library menu. To change the selected part click the expand button on the Select Other Matching Parts section.

33 34

As our guide is based on the Olimex SOM board and to follow the same parts, look for the SN65HVD230D CAN transceiver check the radio button and click to save changes button to go back to the CAN library window. Click the expand button in selected part section to explore more device specific options. Once device specific options are selected click save changes button to complete the CAN part selection.

35 36

Next peripheral to add to the design is USB, application supports USB 2.0, USB 3.0 and ULPI transceivers. To add USB to the design look for the USB Library and place to the editor area, select the library functions and click Get Parts button to let the application select the suitable part. Once the part is selected click the save changes button to finish the wizard. Repeat the steps for OTG and HOST peripheral connectors.

40 41

Circuit tree also allow user to route connector to any interfaces to connector peripherals externally to the board. To add connector to the design, look for the connector block in components library. Once the connector is added to the editor a window will be popped out for connector options. Select the proper sizing of the connector and number convention and click save changes button. Note the connector designator that will be used in next step.

48

Next add UART block to the editor area, now here is a new thing instead of looking for parts click the expand icon under ‘Route Interface to Connector’ section and the connector configuration window will be popped up. Select rout the interface option and connector designator from the previous step. Once done click save changes button to finish routing connector to the interface.

50 51

Same can be done with SPI and I2C interfaces, to add connector to SPI interface place Serial Memory Library block from the library menu select SPI and rest of the process is same. For I2C interface, in Serial Memory Library select I2C from the library functions drop down menu and repeat the same process.

The menu’s are easy to use and the interface has been created for quick turnaround of the design.

Evaluation of circuit tree with a stm32f407 microcontroller board

Here is another capability test we wanted to conduct with the latest set of features. These tests help us check the limits to which we can test our engine check in addition to check the usability of the application.

We choose a stm32f407 reference design from STMicroelectronics for comparison as it is a complex board and our guess is that it has taken several week to design the board.

We quickly pulled in the design which we have created in our example library and selected components such as usb3317 from the usb library as our ulpi transceiver. We let circuit tree design remaining combinations for us. This is the what our design looked like in requirement editor.

STM32f407_Board_Requirement

Circuit tree quickly generated the design for us by doing all the complex tasks behind the scenes.

Let us compare the results. The table below shows what circuit tree could achieve in comparison with the board and what it could not.

Comparison chart

Comparison chart of features supported by the two boards

I am glad to report following findings:
1. Circuit tree did not connect two peripherals in parallel. For instance MicroSD connector and RS232 connectors. It also did not do create connections where audio port is shares pin with MicroSd port ON ST boards. Here are the list of pins allocated by the circuit tree versus the application board.
2. Some of the features we don’t support at the moment but we have capability to do so and extending our capability every day.
3. Finding processor pins for the peripherals, component selection for peripherals, power clock reset, optimisation, decision circuit configuration , schematic generation and check is all done in a shortest span of time. We like to keep things simple and easily understandable for our users which is reflected in our final output.
4. The application schematic generated can still be downloaded in a popular PCB design tool and used for further customisation.
5. The best part is that I can quickly go back to the requirement editor and change
a). The ethernet transceiver to Microchip lan8710 and
b). The CAN transceiver to TI SN65HVD230D and
c). Change zigbee module to Zigbee Internation XB24C module.
d). change input voltage to 9V.

The design file [containing Eagle and Altium] Schematic and the bill of material  is ready by the time i write this. You can check it out through the link below:

stm32f407_design_database

TIP: You could also go back to the board requirement menu ,delete the processor and add any other processor and still generate the design.


 

Short Introduction to Circuit tree

Circuit tree is a online EDA application having intelligence of a hardware engineer to create embedded hardware designs. It features more than 1000+ processors and controllers along with extended hardware peripheral library.

Here is a introduction video to circuit tree:

Schematic Pages of interest you should visit when using Circuit tree application

Introduction

Circuit tree is a online platform to generate a embedded design schematic and PCB placement using a easy to use editor with online library components. The  hardware compiler generates the design in  minutes and we have used the platform to generate thousands of designs and schematics. Whenever a schematic is generated for a given set of requirements, the application output always surprises and baffles us with something new. We get excited to see the generated output as we in no way control

  1. Component selection unless pre-selected from requirement page.
  2. Pin mux selection of the processor
  3. Power and its sequencing, clock, reset generation on the board
  4. Schematic Symbol generation
  5. Circuit connections on board
  6. Schematic Page creation.

This is the amount of variability the application has. This unconstrained output is however tested thoroughly before the schematic is displayed.

Continuing with the above thought we would like to share some of the most dynamic schematic connections generated so that you can understand that each created design is unique and the effort we have invested to ensure that the designs delivered to you are correct.

Use Cases

For this discussion we will be using the hardware compilers and its library components.

  1. When visiting stm32f407 look out how the usb connections are generated. Some of the requirements pictures are posted below in the figure. Also you can select ulpi and try exploring these pages too.

    USB requirement for stm32f407

    USB requirement for stm32f407

  2. When using imx6 controller select rgmii/rmii/mii interface in ethernet  or try pcie implementation. Look how the power sequencing takes places when rgmii phy with two power up voltage steps and imx6 with four power up ramp up steps ramp with with the  remaining circuit.
  3. When using the atmel same70 controller check how the usb connections vary based on the host or device requirement. Here is the final twister. Atmel microcontrollers requires that vddio supply should be above 3.0V when usb connections are being used. Use the atmel_same70q_example1 to commit requirement when
    1. Usb block is present
    2. Usb block is deleted from the requirement page
