layout pin creation after binding the devices between schematic and layout

Inas Mohammed

Hello,

I bind between a schematic and its layout using the bndAddInstsBindingByName and lxSetConnRef. So i can select both the nets and the instances between the schematic and layout.

How can i create the pins to be connected and also use the connectivity to place the pins for each instance in the layout using skill script

Thanks

Regards,

Inas

    Questions:

    1) Why the pins are not created despite mentioning that option "TRUE" in the lxUpdateCompnentsAndNets?

    2) If these options are not written so their default values are "TRUE", correct?

    I suspect that the pins had already been created. Since this is the update components and nets rather than gen from source, it only updates if it deems that an update is necessary. Perhaps you already have the pins present (on another layer) in your layout? In an earlier post in this thread you said they'd been created on OD. If so, you'll need to delete them first and then do the update.

    The default value is not necessarily true - it's the value of a cdsenv variable. If you type arglist('lxUpdateComponentsAndNets) you'll see which cdsenv vars the defaults come from (these are all layoutXL env vars).

    Regards,

    Andrew.
