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

  •  Hi Quek,

     

    I can view the rsf file by pressing the button and the avFlatten function is there.

     

    For the information that you request:

    a) all of my instances are being flatten, basically all of my instances are standard cells which is quite small.

    b) number of device can be different for each cell but since it's standard cell so the device is not much.

     

    I've tested a test case and i can get the instances not flatten

    for the 600++ cells in my layout. i duplicate them( making each instance exist twice in my layout) and with this method only I'm able to make ASSURA not flatten my cells.

    it feel strange for me because it suppose to not flatten my cells even though my instance only exist once in my layout. Can you help me to resolve this? Do you know why the avFlattenCell will only works when there's more than 1 same instance in my layout?

     

    Thanks,
