The following shows what is needed to run dbdiff on an OpenAccess design


You need to first make sure that paths to the Cadence OpenAccess libraries are set correctly.

Here's an example of the needed essentials:

    setenv CDS_INST_DIR /installations/cds/IC6.15.11_Lnx86
    setenv OA_HOME $CDS_INST_DIR/share/oa
    setenv LD_LIBRARY_PATH  $CDS_INST_DIR/tools/lib/64bit:$CDS_INST_DIR/tools/lib
    setenv PATH $CDS_INST_DIR/share/oa/bin:$CDS_INST_DIR/tools/dfII/bin:$CDS_INST_DIR/tools/bin

If cds.lib has the following OpenAccess library defined:
        DEFINE AND2X1 ./AND2X1

Use the following inputs to run dbdiff:

        $MGC_HOME/bin/dbdiff -system OA -design AND2X1 ORIGAND2X1 layout -refdesign AND2X1_2  REFAND2X1 layout -report dbdiff.rpt -automatch
