hi Smile
i use calibre DESIGNrev to open a layout generated by candece first encounter .
in cadence first encounter : i use a map file when streaming out a gds2 layout.

 

when i open in calibre i see those layers , example :
31
31.1
33
33.1
etc....

 

what is the difference between layer number 31 and layer 31.1 ??????

 

how to write the layer properties file in this case ?
and how to write the rules in this case ?
in other words , layer metal1 is no 31
so whats layer 31.1 ? is it metal1 also ????

 

thx for explaining and helping me
