Skill : Unable to highlight all nets of a specific name for hierarchical layout

BabaiVLSI

Hello,

I need to highlight all the nets(even from lower hierarchies) named "bias0". I tried with lntAddTrace(getCurrentWindow() "bias0" ?stopLevel 32 ?hierPath geGetInstHierPath(hiGetCurrentWindow())) but it is highlighting only the nets in current(top) hierarchy, not the lower hierarchies' nets.

Output of geGetInstHierPath(hiGetCurrentWindow()) is nil whereas we have hierarchies in the layout. I don't understand where is the problem happening?

Please help.

  • Well, the hierarchy path is going to be nil because you're at the top level. geGetInstHierPath() is intended to tell you the hierarchical path when you've pushed down through the hierarchy - in this case there's no need for it to be set because you're already at the top level. I'm not sure why your hierarchy is not being traversed - it works for me; the default is to use physical rather than logical tracing, so I'm not sure why that's not going into the lower level in the hierarchy.

    Perhaps you should contact customer support so that an AE can look at it with you?

    Regards,

    Thanks Andrew for quick reply.

    You meant to say that ?hierPath option is not needed for lntAddTrace command as the script is executed from top level. Correct me if it is wrongly understood.

    Let me try out with other foundry PDKs, how it behaves. Then, I shall take it forward with AE.

    That's right, ?hierPath is not needed because you're at the top level. However, it doesn't do any harm to specify it because then your code would also work if you happened to be at a lower level of hierarchy.

    Thanks for your reply!

    I tried with other technology of different foundry but same occurrences. 

    Let me retype the full command I now ran : 

    lntAddTrace(getCurrentWindow() "bias0" ?stopLevel 32)

    It is highlighting only nets present in top level. No net from lower levels gets highlighted.

    I probably have to work with an AE.

    Yes, you should do that.
