Comparing GDS layers

[nabil]

Dear all,

How can one compare two GDS files or two GDS layers using "Assura"?

I mean like XORing two layers and marking the shapes differences.

Best Regards,
Nabil

If you have access to SourceLink, a search for something like
"assura xor flow" should get you a good appnote.

You want ?inputLayout2(), ?cellName2, layerDefs2().

?inputLayout ( "GDS2" "old.gds" )
?cellName "top_cell"
?inputLayout2 ( "GDS2" "new.gds" )
?cellName2 "top_cell"
[rest of rsf...]
drcExtractRules(
layerDefs( "gds2"
m1 = layer( 31 type(0) )
)
layerDefs2( "gds2"
m1_2 = layer( 31 type(0) )
)
errorLayer(geomXor(m1 m1_2) "XOR: m1")
)

Nabil,
If you have access to CalibreMDPV it is the easiest and most powerful
way to view, edit or compare gds files. You can even save off the
comparison results to a new file.
