OP annotation for user created symbols

[yvk]

Hi,

Is it possible to annotate some operating point results onto a user defined symbol after running a DC OP simulation?

And possibly some manipulated op results.


Thanks,

Yes - search in the documentation for opParamExprList.

We have something in the pipeline which will make this much easier and
much more interactive.

Regards,

Andrew.

Thanks for suggestion, I tried this
("gmid" "OP(mappedRoot(\".M0\")\"gm\") / OP(mappedRoot(\".M0\")\"id\")")

adding to 'opParamExprList' didnt change anything.

Here my requirement is to access lowerlevel device parameters

Andrew could you help me in correcting this.

thanks,
yvkrishna

There should be spaces before the \"gm\" and \"id\" - that's wrong at least.

Thanks Andrew, it works after that correction.
How do add some more expressions in the opParamExprList, is it space separated?(didnt seem to work )
what syntax is this ? i dont find enough examples of this kind in the documentation..

If you use cdfDump() to dump the CDF and then edit it, the
opParamExprList in the simInfo will look something like this:

opParamExprList (
("nodeVolt" "VDC(mappedRoot(\".3\") )-VDC(mappedRoot(\".6\") )")

("gmid" "OP(mappedRoot(\".M0\") \"gm\") / OP(mappedRoot(\".M0\")
\"id\")")

)

Thanks Andrew.

Hi Andrew,

How do I use the instance parameters like w,l,m of a mosfet to write some expressions in opParamExprList(and add they themselves also)?

because I have to use pv()in calculator.

Thanks,
yvk

You could use pv("/I1/M1" "w" ?result 'instance) to get these - or you
could get the effective W from the outputs result - pv("/I1/M1" "weff"
?result 'outputs) (I may have the name of the result wrong here, as I'm
answering this from memory).

Hi Andrew,

Is this the entry to write in the opParamExprList

("wid" "pv(inst() \"w\" ?result "instance")")

Thanks,
yvk

Almost, I think (without testing) it would be:

("wid" "pv(inst() \"w\" ?result \"instance\")")

Thanks Andrew,

It works.

Could you point me to latest documentation on how to use OP annotation with 'balloon' on the schematic with 'Annotation Setup'.

Previously I have a bunch of skill functions and I used to call them in the opParamExprList entries.

Now how to do such things in this new setup.

Thanks,
Vamshi

Vamshi,

The annotation using info balloons and the new Annotation Setup form is
in the upcoming IC616 release; it's not officially released yet.

Andrew.
