VCS code coverage merging

[lipmin.khor@gmail.com]

Is there a simpler way of merging coverage in VCS? Modelsim has this
merging option in its new releases, just wondering how other people
are doing it in VCS. The only way I have seen is to create a script
to mrege them manually. Thanks in advance.

Found the option to be urg -dir <name>.cm
But I am facing a bizarre issue now, my simulation runs in normal VCS
simulation but it reports error and stops during a coverage
simulation:
Error: Our calloc(1,52) returned 0: Cannot allocate memory

I am using 2006.06
Anybody seen this before?

Seems like you need more memory/swap.

Thanks Peter,

Yes, I have the same comment from the synopsys support as well and I
am now trying to narrow down what I can do with coverage. I now have
only -cm_tgl portsonly and using -full64 for both compile and
runtime.

Yet it is still not working, the normal simulation works fine though.
I will try to use the SP1-11 patch as soon as I can get it installed,
see how it goes.
I could use mti for the simulation but then the simulation runs
extremely slow as it seems to be lock up in the PLL where the time
resolution is set to 1ps.
This is needed for the PLL to work correctly. I am wondering how I can
speedup this runtime in modelsim.
