Trouble With Layer Name Pair

MarkGorecki

Hello,

I'm using Cadence Allegro 24.1 and I'm trying to check if the layer "Package_Top" is visible and if not, make it visible.

Neither of these commands work:

if(not(axlIsVisibleLayer("STACK-UP/PACKAGE_TOP")) then

if(not(axlIsVisibleLayer("NON-CONDUCTOR/PACKAGE_TOP")) then

I get this:  

*WARNING* Layer does not exist: STACK-UP/PACKAGE_TOP

*WARNING* Layer does not exist: NON-CONDUCTOR/PACKAGE_TOP

If I use just "PACKAGE_TOP", then I get: *WARNING* Layer does not exist: PACKAGE_TOP

Does anyone know the layer pair, or just the layer name that I would use?

Thanks,

Mark

    Ok, got this figured out.  I did a "Show Element" and picked one of the bowties.  It showed the class as "DRC ERROR CLASS" and the subclass as "PACKAGE_TOP".  I used those names in the code, and it worked.

    Years ago, Cadunce changed the naming convention between Allegro and APD ( IMHO that was stupid )

    They finally provided the skill function axlMapClassName() that allows skill code to work with both tools...

    Below is an example that should work in both Allegro and APD:

    (axlVisibleLayer strcat(axlMapClassName("PACKAGE") "KEEPOUT/TOP") t)

    Hi David, thanks for the info.  I have made a note of that.
