[date=2022-08-28 timezone=“Asia/Tokyo”]When I use grlib-gpl-2022.2-b4274, make map\_xilinx\_7series\_lib stalls in designs/leon5-xilinx-kcu105 on Ubuntu 22.01.1 LTS, Vivado Lab 2022.1. Is there any workaround against it?

Hi Hiroki,

If you set GRLIB\_VIVADO\_COMPILE\_VERBOSE=y the printout from Vivado’s compile\_simlib will be printed to the console. Maybe this could help you find where the command halts.

Best regards,  
Martin

[date=2022-09-04 timezone=“Asia/Tokyo”]Hi Martin,

Thank you very much for your advice.  
I checked error messages. It might be caused by the version difference between Vivado and Modelsim as mentioned in section 2.5.3 in GRLIB IP Library User’s Manual.  
I will check further.

Best regards,  
Hiroki

Hi Martin,

I replaced Vivado with an older version, and it has worked !  
Thank you very much for your advice.
