Generating bitstream by following the steps mentioned in this Makefile: https://github.com/Talha-Ahmed-1/picofoxy/blob/main/fpga/Makefile

It got stuck at the time of synthesis and giving such error.

All of my IO ports are mapped in .xdc file. Design resources: https://github.com/Talha-Ahmed-1/picofoxy/tree/main/fpga

The error is ERROR: set_property IO_LOC_PAIRS: Incorrect number of arguments..

My first guess is that something in your .xdc file is currently unsupported by the symbiflow tooling.

@tmichalak Might know what is going on?

[mithro]

Poke @tmichalak ?

[tmichalak]

Sure, I am looking into it

[tmichalak]

@Talha-Ahmed-1 I am not able to reproduce the problem. Can you double check if the xdc and design are up to date?

I believe I get this error when I have had a missing signal in my .xdc file...
