Starting with skill

i knew that we can convert any layout to skill code using dbWriteSkill() command

but when i searched for that command in the skill layout user guide i found nothing so is there another document with another name inside cadence having this command description or guide?

Thanks alot

That's because it's a database function, not a layout editor function. So it is in the Virtuoso Design Environment SKILL Reference. If you run `cds_root virtuoso`/tools/bin/cdnshelp or use Help from the CIW (say), you can search for dbWriteSkill and find it that way.

Note that using dbWriteSkill is not going to write a particularly pretty or reusable piece of SKILL code. So by all means use it to find out the functions needed to create particular objects, but I wouldn't really start any code from it.

Kind Regards,

Andrew.

so you mean use it just to have a guide fro me how to do certain thing with layout but in the reverse way right?

I don't really understand your question. All I was saying that dbWriteSkill merely produces code that will reproduce the cellView in question - it's not a good example of how you would build a layout or schematic from SKILL, apart from learning what the arguments to the individual functions do (which you could also get from the documentation).

Similarly, using the SKILL code from the graphical PCell editor is not a great route either - this graphical pcell interface is very old and has not had significant work done on it for many years now.

Kind Regards,

i want to get the cell view ID so i'm using dbGetCellViewDdId (layout) is there a mistake with what i'm doing?

That rather depends on which "ID" you want. This will give you the "dd" ID (which is a handle on the cellView directory); if you wanted the "db" ID (the CDBA/OA cellView id, with which you can access the shapes, nets, etc or create physical or connectivity objects within, then you'd need whatever you're passing to dbGetCellViewDdId - which is the return value of dbOpenCellViewByType or geGetEditCellView/geGetWindowCellView if in a graphical environment.

Really your questions are too vague to be answered specifically - if we don't know what you are actually trying to do, it's really hard to be sure that we're giving you the answer you need.

Kindest Regards,

Andrew.

You mean for example:

CVID=dbOpenCellViewByType("inas"  "test"  "layout"  "maskLayout"  "r")

dbWriteSKill(CVID.......)

right?
