Automatic VIA Drop for same NET

DannyRitt

Hello,


I am interested to automatically drop VIA using SKILL procedure/command for the same NET.

For example: I have a MESH of Metal2 and Metal3 lines with same NET = VDD.

Is there a command to Drop a VIA array for same NET objects, similar to the "Create Via" form but automatically for many objects, without using the form.


Thanks,


Danny

  • This can be achieved with use of the viaGenerateVias* SKILL functions available starting from IC6.1.7 ISR7.

    Example usage:

    let((cv vopt)

    cv = geGetEditCellView()

    ;;;;;;Get via options

    vopt = viaGetViaOptions( cstFindConstraintGroupIn(techGetTechFile(cv) "virtuosoDefaultSetup" ) )

    ;;;;;;Set via options

    vopt~>automatic~>connectShapesOnSameNet = t

    ;;;;; Generate vias in area:  0:0 10:10 for connected overlapping shapes

    viaGenerateViasInArea( cv list( 0:0 10:10 )  vopt )

    )

    Please adjust as per requirements.

    For detailed information, please refer to: support.cadence.com/.../techpubDocViewerPage;title= Via Functions
