I am getting the following error when running attached design with FIFOs. It generates the eblif file but when running the PnR it gives the error:

Error 1:

@rakeshm75 We are aware of this issue and working towards fixing it. Basically the techfile for PP3 mentions many RAM pins as non-routable while they actually are routable (as in EOS-S3).

This issue should be now solved via #613
