How to Test a custom CAN Controller Developed and Implemented on a Zybo Z7-10 Board

[yaqine]

Hello everyone,

First of all, I know that there is a Digilent Pmod CAN that I can use, but this PMOD already includes an integrated CAN controller. For my internship, I need to implement and simulate a custom CAN IP controller on a Zybo Z7-10 board. However, I also want to perform a hardware test. Can you advise me if you know of a CAN transceiver (without controller)  that I can connect to the Zybo and use, or any method to test it if someone has already tried any of these attempts? Any ideas would be useful to me.

Thank you!

I guess you want to develop the data link layer controller of CAN (?).

The CAN PMOD board just contain CAN transceivers, something to do more with the Physical Layer.

There are CAN core available at OpenCores and GitHub. You can get them and study it.

Thank you @dpaul

Yes, I want to develop the data link layer. However, the CAN PMOD contains also a MCU CAN Controller (data link layer)  and it just communicates with Zybo board with SPI. So i can't use it to test. 

Thank you

In that case you need an add-on board which has only CAN Transceivers and can be connected to your FPGA development board easily.
