Title: Spectre dying
Post by padawan on Mar 19^th, 2013, 6:25pm

Hi,

I've been having some difficulty finishing simulations on Cadence. When I run ADE transient simulation, after some time, the spectre simulation just stops (around 18% of the total simulation). I've been monitoring the resources during the simulation to make sure I'm not running out of memory, nor disk space and I don't see any issues there. ICFB doesn't report anything, neither does the spectre.out file. The spectre process cpu% just stays at zero.

I'm running version 5.1.0 and MMSIM11. Does anyone have any suggestions on how I could fix this?

Thanks,

Are you running the 64-bit binary? You could be hitting the 2GB limit for the 32-bit binary. It does seem like you're running out of something.

Can you find the netlist (input.scs?) and run it from the command line?

I tried to run it thought 64-bit binary through ADE (I don't think I have direct access to spectre because I'm running it through the CMC environment) and I ended up getting the same results.

The only difference I seen is the size of the virtual memory. 32-bit had ~750M while the 64 was ~1G.
