Using DESIGNrev to report all layers in GDS/OASIS file

Version 1

    You can use the "layout peek" command in DESIGNrev to output design layers.

     

    For instance, the example below shows the design contains layer 1 datatype 1 and  layer 2 datatype 0.

     

    >calibredrv -a puts [layout peek a.gds -layers]
    {1 1} {2 0}

     

    The "layout peek" command is documented in the "Calibre DESIGNrev Referance Manual", Chapter "Batch Commands for Layout Manipulation".
