i'm in an asic project
the layout is generated by cadence - first encounter
there are metal layers and text layer generated , example :
layer metal1 31
layer text1 131
and layer text1 is the metal layer associated to metal1 layer
in the rule file i wrote the following :
connect metal1 metal2 by via1
text layer text1
attach text1 metal1
but in the calibre -LVS the following error is in :
attached label "label_name" in layer 131 etc......
same error for all text labels in the layout
then calibre lvs doesn't extract any netlist !!!!
i checked in the layout viewer DESIGNrev and i found that the text labels of layer 131 are situated correctly on polygons of layer 31
what can i do to perform LVS ?
thx for help
