Re-compile Pcells

KishanVNs

 Hi All,

 

I have a Library of Pcells and i have done some modifications to them using db commands .

But when i am placing them in another layout , i am not able to see the changes that i did using the db commands.

I understood that i have to re-complie the Pcells[ compile to pcell not to  skill file ]. The issue is i have around 200 pcells and i want to do it automatically. I don't know what command is used for re-compling [ db command ] and not able to find it.

It would be helpful if any one could post the code for it.

 

thank you

Kishan

  • Hi Kishan,

    Are these graphical PCells (i.e. ones that were drawn and then stretch lines etc. were added to them), or are they SKILL based PCells?

    The way to modify a SKILL based PCell is to modify the SKILL PCell code, and then the PCell is recompiled by loading that code. PCell instances are modified by changing their parameters - this is the only way that you should be trying to modify PCell instances.  Likewise, you should not be trying to alter PCell masters with db commands that run on those cells, put the modifications in the SKILL code that builds the master.

    For a graphical PCell, I have not tried to alter one using db* commands, but even so I presume that if you did this you would need to recompile the PCell, and I don't know what SKILL function that would be - I do not see anything obvious in the SKILL Finder, which leads me to think that there is not a public function for doing this.  Anyway, you are better off using a SKILL based PCell.

    Can you please clarify your request and also mention which version you are using?

    Regards,

    Lawrence.
