skill code needed for connecting via on device to corresponding net below pcell

RAGHU2634

Hi ,

Suppose I know the net names of via's placed on device & corresponding nets in some metal are running below the device. Is there any function in SKILL which can be used to connect via's to corresponding nets

Thanks,

  • Hi Raghu,

    Not sure I understand what you mean. You add a via onto a net using dbAddFigToNet(), but if a via is already on a net, you can't add it to a second net. So perhaps you need to clarify (maybe with a picture) what you're trying to do?

    Regards,

    Andrew.

    HI Andrew,

    Given Below images depicts my question. Suppose i have a device with via (here M1V1M2) & Netname of via is (vdd&vss). Two metals(here M3)are running parallel to device whose netnames  are vdd & vss

     

    Now I need to know whether any skill functions are available to do something like below  .i.e connecting via's to corresponding nets

    Thanks,

    Raghu

    Raghu,

    This does seem to be trying to reinvent the pin to trunk capability that is already in VLS XL. Why don't you use that? You can either draw the VDD and VSS trunks and as you do so use Right Mouse->Finish Trunk or draw the VDD/VSS wire, use Right Mouse->Compose as Trunk and then select the track and use the auto router on that single net from the wire assistant and pick pin to trunk topology.

    I'm sure there's a rapid adoption kit on this. Yes, a 30 second hunt on the support site gave me: IC 6.1.7 Pin To Trunk New Features
