I want to run "set_toggle_excludefile" command . And I pass this command to coverage configuration file . And run that file in elaboration command but it did'nt run.
where to create coverage configuaration file?
Elaboration command is directly run on terminal or give this command to run script or else???
Using the xbus example as a starting point, you can create a .ccf file with any editor.
irun -f ../filelist.f \+OVM_TESTNAME=test_read_modify_write \-covfile ./xbus.ccf \-covoverwrite \-covworkdir ./cov_work \-covdesign xbus_chip \-covtest test_read_modify_write
if you are using 3 step (ncvhdl/ncvlog, ncelab, ncsim):
ncelab -covfile ./xbus.ccf \
Below is a *sample* .ccf file. There are many dozens of options. You will need to review the ICC User Guide to figure out your coverage requirements. This is the *most important* step.
===Contents of sample .ccf====

In reply to tmackett:
How to deselct the coverage for the modules which are instantiated by generate block. I deselct the modules but still i can find the coverage .
