how to generate ASSURA DRC error report that shows which instance has error?

llobak

Hi,

 I would like to generate a ASSURA DRC error report  using SKILL. i've managed to do it by reading the *.err file. But I hope to refine my report by specified which instance in my layout that has DRC error. Can anyone give me some guide? Thanks.

 

Example: in my layout i have instance A, B, and C. If only instance C has DRC error, how can i make my report to show that instance A and B are clean but C is dirty?

 

Thanks,

SL

    It might be that your instances A1, A2 and A3 are quite small and hence were automatically flattened by Assura for more efficient hierarchy handling. You can disable small cell flattening by using the avFlattenCell procedure which can be accessed from the DRC form. For hierarchical drc, the names of the subcells will be included in the err file. Try using some larger subcells and I think you will be able to see their cellnames.

    I assumed that you must have already written the codes to parse through the err files for all the coordinates and cellnames. The error cell list will have to come from there.

    Since your layout only consists of non-overlapping instances, then perhaps you can also use dbGetOverlaps cmd to find the instances.
