SKILL: How to modify an existing net name?

Hi All,

I have written code to add a net expression to all the global signals
in a cell, however, it does not make change to the signal's net name.
The command I am using is:

dbReplaceSigExpr( cv netexpr )

it only add a property name and default name to the net.

I am wondering is there any command that I could use to make changes
to an existing net name?

Thanks,

Min

Hi Riad,

I was doing exactly the same thing as you mentioned in the link to add
the inherited property to the global signals.
But the problem is that, with the accompany of

dbFindSigByName()
dbReplaceSigExpr()

I am only able to add a property name and default name to the global
signals but not changing the net name.
The thing is, in my library there are cells with different net names
for global substrates, some are named "sub!" and "SUBC!", so I have to
make them consistent,
so that it would not cause any lvs problems in future designs.

Do you know the difference between a signal and a net? and is there
any commands that is able to make change to the net name?

Thanks and regards!

By the way Riad, I think the modification would be saved without the
line "schCheck(cv)",
but I don't why.
