Devin,
Mapping a signal from the ad9361_data_sub device worker to a pin name in the XDC is certainly a valid action. To help further debug the error, can you send us the following:

  1. The line in your .xdc containing PAD_PL_CAT_P1_D_6
  2. Your assembly .xml
  3. Your assembly Makefile
  4. Your assembly container .xml

Thanks,
Brandon

Subject: [Discuss OpenCPI] hdl platform port mapping


We encountered the following error regarding external signal PAD_PL_CAT_P1_D_6

We are attempting to map the signal from the AD9361_data_sub platform worker to the correct pin name in the platform XDC file.

Included below is a subset of the device worker instance. Is there an issue with how we are mapping the ports in the platform spec?

Is it necessary to specify these signals in the hdl container and/or assembly also?

Our alternative approach is to modify the XDC file to match the pin names to the AD9361 worker port names to alleviate the need for port mapping, however we need to understand how to map the ports.
