delete existing wire from a terminal and redraw a new one.

AdeshNamekumar

I'm trying to redraw all nets on the bulk terminal of all instances by deleting exisiting nets after extracting information about the net label name from them. I have the working SKILL to redraw the nets at the bulk terminal but I'm having trouble deleting the existing nets. 

if cvSch stores the cellView id. 
This is what my snippet looks like:

BulkSignals = "x y z"
BulkSignals = parseString(BulkSignals)

foreach(biasinst cvSch~>instances

; loop through all the terminals of each instance
foreach(myTerm biasinst~>instTerms
if( ( myTerm~>name == "B" ) then
biasnet = myTerm~>net~>name

if((setof(x BulkSignals (x == myTerm~>net~>name)) != nil) then
foreach(fig myTerm~>net~>figs
if(((setof(x BulkSignals (x == fig~>net~>name) ) != nil) && fig~>children != nil) then

schDelete(fig)

function call to draw the new net
)));all loops end here

The problem in using and deleting "figs" is that it has all instances of the same net name rather than just the one specific to the instance I'm presently looking at. As a result, I'm deleting 'n' number of wires at once instead of just one,

I did find a work around by including the fig~>children condition to but now I see warnings as follows:
dbGetq: object is a purged/freed object - db:0x158bb9c4

Is there an easier way I can do this? I've seen a couple of related posts but can you be more specific?


Thank you,
Adesh

  • This still isn't very precise which is why I suggested you contact customer support (you ignored that part). For a start. it's hard to understand why you want to delete and recreate it with the same net - what's the point? Also, you're talking about deleting the net - do you mean delete the all the wires on that net, or just the segments connecting to the bulk pins? Or should it delete further than that? When you are recreating the "net" (the wiring) how are you determining the geometries for that wiring?

    Note I'm not expecting you to answer these here, as without some examples of what you're trying to do, it's very hard to give specific advice. That's why I suggested contact customer support, so you can share some actual examples rather than just incomplete descriptions.
