Diff Symbol views

rajivsub

Hello -

I am trying to write a script that will diff two symbol views. This is needed for library validation.

Before I try doing this in SKILL, wanted to see if there was anything generic that already exist to do this. Any ideas if there are already code snippets for this or if there is a SKILL function to do so?

Thanks much.

  • Hi,

    Typically this is done for layout views.  I understand a common technique for layout is to perform an XOR (exclusive-OR) of the two views and any output is the result of differences between the two input views.  However, I am not sure if you can use the dbLayer* functions for a schematic view, I have not tried this.  There is a dbLayerXor() function:

      dbLayerXor(
     d_cellViewId
     t_layerName
     l_dbIdList1
     l_dbIdList2
     [x_numVertices]
     [g_mfgGrid]
    )
    => l_dbIdList

    Try it out and look at the documentation for more information if needed.

    I hope that this helps you.

    Best regards,

    Lawrence.
