attaching multiple connectivity to a source/drain of a fet |
|
|
In a normal configuration of say a 2 fingered fet device which has a
single net connected to D(2 drains), S & G respectively one can attach
the term in the following way,
given are netName(for example "a") , term( for example "D" for drain) &
the instance(inst)
I can do,
net = dbMakeNet(cv netName)
termNew = dbFindTermByName(inst~>master netName)
(dbCreateInstTerm net inst termNew)
And this will attach the net to the terminal. In this case the two
drains at the end of fet device have the same connectivity to net "a".
If I need to make a configuration of a fet device ABBA, where A & B are
fingers of two seperate fets which share the same drains but are
connected to different sources... In which case the combined fet will
have different connectivity for the sources.
How will I using skill be able to attach two different connectivity to
the drains that are part of a single fet device?
Thankyou,
Partha

correction:
where A & B are
fingers of two seperate fets which share the same drains but are
connected to different sources
should have been:
sharing the same source and connected to two different drains... |

Need to make a cosmetic correction again in my post:
I need to make a corection in my post,
before:
given are netName(for example "a") , term( for
example "D" for drain) &
the instance(inst)
I can do,
net = dbMakeNet(cv netName)
termNew = dbFindTermByName(inst~>master netName)
(dbCreateInstTerm net inst termNew)
corrected:
given are netName(for example "a") , termName( for
example "D" for drain) &
the instance(inst)
I can do,
net = dbMakeNet(cv netName)
termNew = dbFindTermByName(inst~>master termName)
(dbCreateInstTerm net inst termNew)
