Power SI - Query on Retrieving Connected Objects from a Net in PowerSI 2021.1 Using TCL

ABIKRISHNA

Hello Team,

              I am currently working on automating a task in PowerSI 2021.1 using a TCL script. I would like to retrieve all objects connected to a given net or any other objects, similar to how we use axlDBGetConnect in Allegro.

Specifically, when I provide a net name, I want the script to return all connected elements such as:

  • Vias

  • Components / pins

  • Traces / clines / shapes

In Allegro, axlDBGetConnect allows us to easily find all elements connected to a given DBID. I am looking for an equivalent or recommended approach in Sigrity PowerSI TCL to obtain this connectivity information.

Could you please let me know:

  • If there is a direct TCL API or command in PowerSI to query all objects connected to a net

  • Or, if not, what is the recommended workflow to extract this connectivity data programmatically

    Hi ABIKRISHNA,

    You can try below TCL to get details like Trace, via, Node, components, shapes etc., for a particular net.

    sigrity::showObjectsofNets -nets {<Net_Name>} {!}

    I've tried it in PowerSI v25.1 release and got expected results, so you can try it in v21.1 release to see how it goes.

    Thanks,

    Shiva Shankar M
