Operating Region of transistors

AtaV

Hi everyone,

I have a circuit with couple of subcircuits inside it. I was wondering if there is a way to have a print of operation region for all transistors inside all subcircuits to make sure that all transistors are in saturation. I don't want annotation of them on the schematic since I have to go inside them individually to check for it. I would appreciate any sort of help in this regard.

Thanks,

Ata

    In the CIW you could just type report() (an OCEAN function), or report(?output "myFile") to write it to a file. You could narrow down the devices or the parameters - for example:

    report(?output "myFile" ?param '("vds" "vdsat"))

    The exact parameter names will depend on the device type being used.

    I also meant to say that in ADE XL/Explorer/Assembler you could use checks and asserts to check for a device being out of the desired operating region and could then query for any such devices - there are Rapid Adoption Kits on support.cadence.com that cover this kind of thing. That would give  you an easy way of finding them and visualising the results without having to visit every circuit in the design hierarchy.
