I'm trying to extract the intrinsic Nwell- Psub diode area for accurate modelling. How can I make Calibre LVS to recognise the intrinsic diodes and compare the diode area against a schematic model?
Declare your diodes as D devices as discussed in the SVRF Manual under Device. The property AREA is calculated and netlisted by default for built-in diodes. D properties are calculated internally as follows (you do not need to explicitly provide the property computation program unless you want to modify it: [ PROPERTY A,P A = AREA(diode_layer) P = PERIM(diode_layer) ]
[ PROPERTY A,P A = AREA(diode_layer) P = PERIM(diode_layer) ]
Notice that for property tracing purposes, the property name is "A" and not "AREA". To compare the layout and source properties, you would do something like this:
TRACE PROPERTY D A A 0
