SKILL: How to change net name?

[Min Ting]

Hi all,

I am wondering is there any command that I could use to change the net
name of net in a schematic?
The thing is, there are two conventions for substrate in my cell
library, one is "sub!" the other one is "SUBC!", so I am trying to
change all the "sub!" to "SUBC!"

What I am trying now is:

use dbFindNetByName( cv "sub!" ) to get the net object id

and then use:

schHiReplace(
[ g_replaceAll ]
[ t_propName ]
[ t_condOp ]
[ t_propValue ]
[ t_newPropName ]
[ t_newPropValue ] )

to make the change, however, it is always complaining about the
propName, I am wondering what do I suppose to specify for that field.
Or is there any other commands would do the job?

Thanks and regards,

Min

Hi Min,

A clean way to do this, from a connectivity point of view, is to use dbMergeNet(oldNet
dbMakeNet(newNet)). [Not 100% sure of the order of the arguments to dbMergeNet].

But this will only change the connectivity in the database. If you want a working schematic, you
should rather change the label(s) text, before schCheck()'ing your schematic cellview. You might
also want to look for pins, if there is a possibility that pins exist on that net (which doesn't
make too much sense for a global net, unless that net has a net expression).

here's a starter, off the top of my head:

setof(x cv~>shapes x~>objType==label && x~>theLabel=="sub!")~>theLabel = "SUBC!"
dbSave(cv)
schCheck(cv)


Hope this helps.
Stéphane

Hi,

I am wondering for the label, should I use "netName"?

Thanks,

Min
