how can we detach/attach a net to FTerm?

archive

we know that we can detachTerm attachTerm  to connect an net to an comman instance term.

But when I apply it to that idea to FTerm, which is the I/O pin of my current Top cell. I can not change the connection relationship between the IO pin and it's dangling net.  is there an command to achieve that ?

And I'd like to say thanks to Bob   and  Li-Siang,  this  Forum really help us a lot!

  • As a backend engineer, I don't know much about the verilog netlist. Just now, I searched the netlist, and I did not find any assign statement in the it.

    I got the netlist from my frontend parterner, when I load them into encounter.
    Yes, the the IO pin and it's dangling net have the same name, and this net have only one term, which menas dbNetNrTerm $netPtr will return 1.

    So my quesiton are rather straightforward:
    1. can we detach this kind of pin and its net
    2. I can add a net by the command addNet, and then connect the net to IO pin.

    of cource there is no need to do these two step, but I just curious about this idea. As I always said, we need think a step further, the norminal term is OK, how about The FTerm?
