Polygon Reentrant and skill

Hello All,

i would like to create a polygon in my layout using skill. The
coordinates are coming from a text file (let's say a drc.db file ^^' )

Before creating my polygon, i would like to check if my list of points
is correct. i mean no re-entrant, because Cadence does not like that.

I found the function geIsPolygonReentrant, but i can not use it (i
think) because my polygon is not created yet : so i can not provide
any cvid ...

so i would like to know if someone knows a function that can do this
job : checking my list of points .
If this function does not exist, how to do ? I'm using Cadence
5.10.41.

any advice is welcome.

Thanks a lot for your time and your help.

regards,

bubu

 

Hi,
Not sure why this function requires a cellview id. If you have at
least one cellview open, you can pass that cvId. Essentially you are
going to create polygons in some cellview, open that cellview before
this check in the SKILL code, and pass that cellview id to this
function.

that by myself.
