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.

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.

Evaluation of circuit tree generated schematic design with a AM3352 SOM EVB Board

We would be running a capability test with a circuit tree processor library part am3352 processors and a olimex based design which is a open source hardware boards listed at

Olimex SOM EVB

and

Olimex Am3352 SOM

The purpose of the test is to check the following

  1. Components selected by circuit tree and its comparison with the various peripherals selected by olimex Board.
  2. Pin Mux connections from the circuit tree versus the board.
  3.  Power, clocks and reset component selection and strategies by circuit tree engine to generate the design.

The processor lies on a system on module which connects with a base board where other peripherals are listed out. Our first goal is to create a board with similar peripherals connected by the olimex design.

We entered the requirements in the requirements editor as shown below in the picture and then generated the design. For more details of how to enter a requirements you can refer our post Guide for creating a fresh design

Am3352 board requirement

Am3352 board requirement

For more detailed overview of the requirements addition process we have covered it in our next blog.

The design generated by the circuit tree matches the am3352 design in terms of peripheral connectivity. There were differences in some parts which can be seen in the table below.

olimex

Circuit tree engine is able to generate a complex board design/schematic in a minute’s time after all the requirements are entered. We understand the pain of generating a embedded design and allowed the tool to simplify the complete design generation.

The generated design along with the bill of material cost can be downloaded through the link for the comparison.

Circuit tree now supports close to 1000 processors and number of peripherals components. Generate instant schematic design and much awaited pcb placement in few minutes to bring your product closer to completion using the application.
