How can I get the name of all instances in schematic

Well:

cv=geGetEditCellView()
instNames=cv~>instances~>name

will give you all the instance names. Determining whether they are MOSFETs or not is going to be slightly tricky because there's no real indication of that at schematic level. If you have a set of known component names for the MOSFETs then you could do:

mosfetNames=list("nmos1v" "pmos1v")
cv=geGetEditCellView()
mosNames=setof(inst cv~>instances member(inst~>cellName mostfetNames))~>name

Hi Andrew,

Thanks a lot, it worked perfectly.

Best regards,

Hi Andrew,

Thanks again for your answer. Just one more question, if you don't mind:

Is it possible to do exactly the same thing, as above, but hierarchically, ideally by clicking on the cell?

Best regards,

Pedro

Hi Pedro,

There are numerous bits of code in these forums to do hierarchy traversal (generally done using a recursive approach) and then you could collect the instance names as you go along.

Why do you want to do this?

Andrew.

Hi Andrew,

I did a small script, that served the purpose, but is very rudimentary. It accepts names of MOSFETs and op parameters (gm vdsat region etc), generates the OP expressions and adds them to ADE-XL/Maestro outputs.

It's something like this:

myScript(("nameOfTheTest") ("/M1" "/M2" "/M3" "/opamp/M1") ("gm" "ids" "vdsat"))

I would like to polish it a bit more so that, instead of manually entering the name of every single device, a list of all devices could be displayed so the user  can select them.

Cheers,

Pedro

For the MOSFET detection, you could query the devices from the Custom Constraints registration, if available in your PDK setup.

e.g. ciGetDeviceNames("fet") should give you a list with libName and cellName of all available fets. This you could use to check the libName/cellName of your instances.

You might be better off adding device checks rather than a specific output for each of these operating point parameters for every transistor - that could explode the number of outputs. The device checks capability would allow you to add checks for the allowed values of gm, ids, vdsat for every instance of a model or subckt (say) and then report the failures in a queryable table.

Other than that, you could do as I said before and traverse the hierarchy recursively to visit each hierarchical path and collect the hierarchical instance names that way.

Andrew.

Hi Andrew,

I think I was not clear enough. Apologies for that.

I just want to go down the hierarchy, so I can present a list of all the cells below the current one (on a drop down menu maybe), so the user can choose , for eg, 2 transistors from on level, 4 from the other, etc. Basically I would like to have a list of all the levels below the current cell.

Thanks in advance.

Best regards,

Pedro

Hi Pedro,

I understand - I just don't have the bandwidth to write the code for you - hence me giving you suggestions as to the approach you could take.

Regards,

Andrew.
