How to prevent parameter updates for pending simulations during ADEXL simulation

Changing Tests, Global Variables and Corners will not affect already submitted runs. Changing the schematic (in ADE XL) will though, if the netlisting has not happened yet.

This is best solved in ADE Assembler when using "LSCS" as the job submission type (from other posts you are using IC6.1.7 and LSCS didn't exist then - you should switch to IC23.1). That aims to get netlisting done at the beginning which avoids the problem.

With ADE XL, the workaround is to set this in your .cdsinit :

envSetVal("adexl.simulation" "ignoreDesignChangesDuringRun" 'boolean  t)

You should restart ADE after setting this in the .cdsinit and in the CIW (or restart Virtuoso). The downside of the above is that it will do netlisting at the beginning in the foreground and block the UI whilst it is doing that. LSCS handles this better as the netlisting is still done in the background.

Hi，Andrew

Thank you for your explanation. If I use config in adexl, and then I modify the config configuration halfway through, is there a way to achieve the above effect?

ignoreDesignChangesDuringRun solves that problem too. I should have explained that - sorry. It affects both the schematics and the config.

Hi，Andrew

I used ignoreDesignChangesDuringRun.

When using config, the config is changed halfway through, and the pending simulation is also changed.I checked the netlist.

I'd be rather surprised, since it creates all the netlists up front and is blocked whilst it is doing so.

Did you get a popup at the beginning of the simulation showing that it was netlisting. Something like this:

Andrew

yes,it popuped.

My test method is: I use config to simulate a comp, the comp contains two views, schematic and schematic_test, max jobs is set to 1.the comp is initially set to schematic, when I click on run simulationb after two minutes, then I change the comp to schematic_test.I looked in netlist and found that all simulations since then have used schematic_test.

Which IC sub-version are you using? getVersion(t) in the CIW will tell you this.

Andrew

"@(#)$CDS: virtuoso version 6.1.7-64b 11/09/2015 12:45 (sjfnl165) $"

I tried with that version, and it works fine for me. I changed the config mid-run and all sweep points used the original config (I did something in the view I switched to make the simulation fail, so it would have been very obvious).

However, is there a good reason why you're using the base IC6.1.7 release (not even a hotfix) which is almost 10 years old?

I would strongly advise moving to using ADE Assembler in the latest version and use LSCS. I'd be surprised if you see this issue then. Pursuing why this doesn't work in a really old, long-unsupported version is not something I can realistically spend time on.

Hi，Andrew

Thank you very much for your assistance.

You are correct. I tested the assembler using version 617, and it works properly. However, because I have written a significant number of bindkeys for ADE XL, migrating them to the assembler feels quite cumbersome, which is why I have continued using ADE XL out of habit. Additionally, I also tried version "@(#)$CDS:virtuoso version 6.1.8-64b 09/03/2024 19:11 (sjfhw316) $" on the same computer and encountered the same issue as with 617. For now, I plan to gradually update the bindkeys to the assembler when I have free time in the future.

Thank you again for your help.
