Long startup for simulations using ADE-XL

Hi,

 

I was wondering why my ADE-XL sims were taking so long to run, and looking through the log showed me that a new Cadence icfb session is being started for each single run! That does seem a bit well ($%#*&%*&) when all that is needed is a Spectre run.

Is there any way to get the tool to merely start Spectre runs rather than entire Cadence sessions? It can't be something meant to rack up more licenses since Spectre licenses (which are really needed) are anyway far more expensive.

Thanks,

Vivek

     Just for the record. I set the linger time to a large value and set the option to prevent .cdsinit from being loaded by each new ADE-XL job, and there is remarkable improvement in the speed now. As a matter of fact, the simulations start immediately in the later runs as the ADE-XL jobs are already running in the background.

    At present, this works only locally as distributed jobs are not always started on the same machine for successive runs. However, that's another issue.

    Sunil: I did try to set the default history entries to be larger than 3 but it doesn't seem to work. Anyway, I think I can lock previous runs and then they ought to be retained then as locked runs do not count towards the quota of 3 history entries.
