Test if a technology supports layer coloring

psill000

I have some scripts that work with getting layer coloring, but there dont work with older technology that does not support coloring.

Sorry I dont have the print out error in the CIW, but believe the script did not work and gave some message about the unsupported coloring in technology.

Is there a function to test if the technology does or does not supports coloring?

    Hi Paul,

    Not really. The closest (I think) is techGetProcessNode() but that is only available from IC618/ICADVM181 onwards (I think) and it requires the processNode to have been defined in the tech file...

    One thing you can do is to call:

    techGetLayerNumColorMasks(tf "Metal3")

    (on the relevant layers you care about). This will return nil if there's no coloring of that layer. You do need to be using an Adv Node enabled release though (so this won't work in IC617/IC618). I'm assuming you're in an Adv Node enabled release and just want to determine whether the tech supports coloring.

    Andrew.
