Here is a method for comparing two ASCII results databases to check for differences. It involves a few scripts and uses DESIGNrev to convert the ASCII results databsaes to GDS files, then Calibre DRC to compare the GDS files, and Calibre RVE to check the differences between the GDS files. There is also  some example data that can be used to test this flow.

 

Here are the names of the two scripts that will be used:

 

convert.tcl

result_in_overlay.tcl

 

Here are the names of the two files for the example data that can be used to familiarize yourself with the flow:

 

1.drc.results

2.drc.results

 

There is also a README file that describes details about the inputs and outputs expected:

Those scripts, test data and README are in a compressed tar file attached to this document and named "compare2rdb.tar.gz".
