ISIM FATAL ERROR

Ther attached code fails to simulate with ISIM with the following error message

 

ERROR: In process xyz.vhd:read_cmd

 FATAL ERROR:ISim: This application has discovered an exceptional condition from which it cannot recover. Process will terminate....

 

This code is a testbench for an up/down counter. The driving commands and test vectors are read from text file commands.txt. commands include reset, load, check, count etc..

The issue arises when my command.txt file contains an unexpected cmd i.e when "others =>" is exercised from the case statement.

 

Any ideas why this might be?

Re: ISIM FATAL ERROR

Hi @kpatel94126

 

I get the following warning with Vivado and looks like the counter module is missing.

WARNING: [VRFC 10-122] counter remains a black-box since it has no binding entity.

 

Please post the complete project archive.

Thanks,Vijay
