Can ISIM simulation data be logged?

Looking for a method to export ISIM waveform data as text data to review later.  Specifically I have large data registers that I need to review content and the graphical representation is tough to review.

Hi @steve_av
You can dump the signals of interest into a VCD file.

that really doesn't give me what I'm looking for.  Whats interesting about the generation of the vcd file is that it's not written to the hard drive until you close ISIM (at least that what I saw after doing the flush command).

 

Anyway, what I'm trying to create is a list of value that my logic calculates.  Would have been nice if ISIM had a feature to dump values out but it looks like I'm religated to doing this in a test bench.
