I'm working with a small (very small) SRAM circuit. I'm simulating the design using Spectre from within Cadence (icfb). I'm VERY frustrated with the waveform viewer that pops up when the simulation is done. I'd love to write out a .vcd file and use a viewer that undoubtedly will be more suitable for debug of a "digital" design. I plan on using GTKWave since it's free, though if i had access to nWave (part of Verdi, formaly Debussy) i'd do it in a heartbeat. Any help would be appreciated, even if it's to point me to another forum.
By the way, a user (TAM1) has already kindly pointed me in the direction of the '-input mycmdfile.tcl' option for the simulator, then, add a couple of lines in that file instructing the simulator to dump the .vcd file for all levels. However, it seems that spectre doesn't like tcl commands (or at least the -input option).
Great info. Things are starting to fall in place. Yes, i'm using AWD (i was instructed to do so by the teaching assistant that taught the class on Cadence). However, I do have the option of wavescan, which i might play with if you think it'd be better.
Since i'm a student, i don't have access to customer support. Only the admin (my instructor) has access and he has respectfully declined to be the liason for me. So i'm stuck doing everything through the forum. I did try to sign up for an account that would give me access to customer support, but the account creation process asked for a key (or some sort of license number).
Lastly, I'm not sure i have access to any newer version of Cadence (IC615) so i'm not sure i can use viva. If i did have access, i would either have to search for the path as my "which icfb" simply returns /usr/bin/local/icfb (with no version discriminator in the path). I guess they could be running a version control tool, but i'm unfamiliar with the environment and would have to ask. I looked through my environment variables and didn't see anything that would point me to a version control hook, but that doesn't mean there aren't other ways of doing it.
