Hello
I am using ModelSim to measure code coverage and have problem when
merging individual simulation results into a single database using the
vcover merge command. I use it as shown in the manual (*):
vcover merge coverage_results ucdb/*.ucdb
where ucdb files are individual results and coverage_results is the
output file. I invariably get the message "File '*.ucdb' is
unreadable". why can't I use a wildcard ?

(*) these two lines are copied from the command reference :
vcover merge myresult2 /dut/*.cov
Uses wildcards to merge all files with a .cov extension in a particular
directory.

You should use the TCL glob command. Try

eval vcover merge coverage_results [glob ucdb/*.ucdb]

(Wildcards do not work inside the GUI when TCL is active).

But I use in in command line mode (DOS window under Win XP). Should I
use the -c switch ? (I am not even sure it is valid for vcover merge)

Hi,

I have a same problem while merging individual .ucdb into single .ucdb file.

I am using below command to merge individual *.ucdb files
vcover merge -out final.ucdb write.ucdb read.ucdb

Error stating : Segmentation fault.

Can anyone have idea!!

Looking forward to your quick reply!

Quick reply? You are kidding when it took you 10 years to reply?

When a post is more than a few weeks old I recommend starting anew.
