How to change TR's G/S/D Connectivity ? Please tell me solution TT

HJC

Hello. please tell me solution to solve this problem TT

i want to change TR's connectivity (Just use skill)

i find individual TR's port and net name (such as G/S/D)

but, i'm stuck in this problem.

how to solve the problem and what's the problem of this part ?

I want to use this command... and change b's value from "net1" to "net2" , but below command is not accessible..

a = geGetSelSet()

b = caar(a~>instTerms)

b~>net~>name 

[result -->  b = "net1" ]

b~>net~>name = "net2" <-- Can't accessible

help me ....

  • Some strange terminology here - does "TR" mean "transistor"? What does "TT" mean?

    Anyway, you can't assign the net names on an instTerm, but you can assign the net. So you'd do:

    cvId=b~>cellView ; or you could use geGetEditCellView(), but getting it from the cellView containing the instTerm would be fine
    newNet=dbMakeNet(cvId "net2") ; if net2 doesn't exist, it will create it - otherwise retrieve it
    b~>net=newNet

    You didn't say whether this was a schematic or a layout (it's the same for both), but one thing to be aware of is that the schematic extractor would likely rename the net at the next "check" because it derives the net names from wire labels, pin names etc. You typically need to add labels to wires (or rename those labels) to change that.

    thanks for your answering !

    'TR' means Transistor // 'TT' means SAD emotion .... Sorry ...

    and i want to use this command in layout view.

    For future reference, please read the forum guidelines (note in particular the very last bullet!).
