adding more OP parameters in DCOP annotation by editing the

[yvk]

Hi,

I know how to edit the CDF parameters for adding more OP parameters while annotating to schematics and have few more queries..

1. How to save this updated CDF properties permanently for a given library ? I tend to loose my changes when I restart Virtuoso.

2. Is the limit for annotation only 4 parameters for MOS? and why ?
what about other devices -bjt,res.cap etc ?


Thanks,
yvk

You need to set the CDF type to "Base" to make the change permanent.
There's no limit to the number of parameters - but you do need a
cdsParam() label on the symbol to have somewhere to display it. In the
future you'll be able to use balloons to display the info rather than on
pre-defined labels - but for now you must have a label slot to show it.

Some PDKs have 7 labels - it depends on who created the symbols!

Looks like I dont have permissions to makes it "Base". Is there any alternative?

Other than using SKILL to redefine it in every session. Note however
that if you use File-Refresh and refresh the CDF, it would discard the
changes then - so it's not really a good solution.
