Error in Elaboration in UVM environment

sunil kr

I am trying to test the VHDL DUT in UVM environment and as i can see using the libverbose all the units are properly resolved when i used irun and it shows error in elaboration as below :

irun: *E,ELBERR: Error during elaboration (status 1), exiting.

I am not able to see any other error messages.

Can you please help me how i can further debug to know the exact reason for the error ? 

  • The full log file would be really helpful in diagnosing the problem.

  • ncelab: *E,ICFNR: Cannot open instrumentation configuration file raccu_cov.ccf.

  • I have connected the ports using $nc_mirror and hence those warning message "Too few entity port connection"
  • The error message is a few lines above that: ncelab: *E,ICFNR: Cannot open instrumentation configuration file raccu_cov.ccf.
  • If i remove the coverage related files then i am able to resolve the issue. Thanks

  • Hello, everyone I'm new here and want to know how to work with MATLAB software.
