How to ignore some minor dots in streaming out the gds file

SUEE

Hi

Please do me a favor.

I am comparing two gds file using dbdiff and then Calibre RVE.

In the result I found many differences come from the many small tiny dots in the layout. These dots are tiny but seem to be still generated by the gds stream out process. So my question is, how to stream out a gds without these tiny dots ? 

How to setup the minimum shape size to be streamed out? Or say how to filter/ignore tiny dots/shapes ?

Thank you !!

  • Thank you, Andrew.

    1. I used  /IC5.10.41.500.3.34.lnx86 to stream out two gds files

    2. Then used dbdiff -system GDS -design xxx.gds xxxl -refdesign yyy.gds yyy -rdb dbdiff_result.rdb to generate rdb file

         ( /cad/mentor/2011.1/ixl_cal_2011.1_15.11/bin/dbdiff )

    3. Then in Virtuoso open Calibre RVE to see the result

    4. As I mentioned I found thounds of tiny dots in the layout that cause the difference between two gds files

     

    Thank you !!
