Signalscan .trn file format.

Hi.

I'm looking for a description of the .trn file format, for extraction
of simulation data without the need for running signalscan. currently
I'm doing this in "batch" mode usin a .do file for writing a VCD, but
launching signalscan takes too long.

BTW, the only possible output I can get is a .trn file.

TIA,
Yaniv.

The trn format is proprietary and not documented if memory serves me
right.

Why don't you generate the VCD file directly using $dumpvars?

If you are using NCSim (and I assume you do :) you can create a vcd
file during simulation with
ncsim> database -create vcddb -vcd
ncsim> probe -create ... -database vcddb

Thanks,

Because, as mentioned, this is the only possible output I have - I'm
using a closed system.

What do you mean by closed system? That you don't have write access to
any of the file systems on the machine?

No word on the cost but it's probably not cheap.

I'm amazed the site is still up. Design Acceleration was bought
by Cadence years ago. Yes, there's an API, but if what the OP
wants is VCD, then .trn -> Signalscan -> VCD is certainly the
roundabout way to go.
