Multiple WLF in ModelSim

[Muthu]

Hi,
I am using Modelsim for my functional simulation. A test case will run
for 2ms - Simulation time.
Opening the vsim.wlf created for 2ms simulation time is very slow for
analysing it.
So, i am thinking of a 2 WLF files for a test case.
ie., vsim1.wlf --- 0ms -- 1 ms
vsim2.wlf --- 1ms -- 2 ms
How can i do that for a single test case?

Thanks in advance.

Regards,
Muthu

You can use the wlfman tool to split the original wlf to several pieces.
Also new Modelsim versions are much faster in reading wlf files (5.8 especially).
I have used few gigabyte sized wlfs without any problems.

Hi Kim,
Thanks. I tried with wlfman. Quite interesting...
Is it possible to generate different dump files while running the
simulation itself ?
