Update P-Cell calculations

rodneyc76 over 16 years ago

Hi,

I'm trying to write a skill script to update pcell parameters for a schematic, and then run a simulation.

With help of forums so far, I've been able to get to updating the parameter width parameter:

cv = dbOpenCellViewByType("afe" "amplifer2" "schematic" "" "a")
inst=dbFindAnyInstByName(cv "M5")
inst->w="34u"
schCheck(cv)
dbSave(cv)
dbClose(cv)

However, is there a way to force the instance to execute its pcell callback to update all the other parameters than depend on "w"?

Thanks!

Rodney

Hi Rodney,
There is a solution for this on the Cadence online support website: Solution 11018344
Hopefully this answers your question completely.
Best regards,
Lawrence.

Hi Lawrence,
I'm using the skill code from
http://groups.google.com/group/comp.cad.cadence/msg/4dae4e6c08b6278d?&q=trigger+callback
I should have the sourceLink solutions after our sys admin can log in and grab them, but your post pointed me in the right direction, and its working perfectly.
Thanks for the quick reply.

Hi Rodney,
I am glad to hear that it is working. (Good job Andrew, it is still one of the most useful and frequently used bits of code I've seen)
Yes, that is essentially the same solution though Andrew has updated it so the Solution date appears to be older, however there is a little more commentary in the Solution, so it is good to read both I think.
Regards,
Lawrence.

Hi Rodney,

I assume you mean CDF callbacks, as there aren't such things as pcell callbacks. Look at sourcelink solution number 11018344 - it gives SKILL code to do precisely this.

Best Regards,

Andrew

I'll check the solution and update it to the latest version of the code. Any difference is likely to be minor though.

Cheers,

Andrew
