Power MOSFET/IGBT in Cadence

goofycat

Hi,

We know that Virtuso is the standard for analog IC. That being said, power MOSFET is also important in analog design, but it doesn’t have simple geometry as PMOSs. They have VDMOS and other geometries and are not easily modeled in layout XL.

I also looked at TSMC PDK other PDKs and they don’t have power MOSFET primitives.

1. Does cadence offer any tool for power MOSFET and IGBT like designs? Do they have standard/parameterized cells as for digital logic?

2. There are TCAD tools lke Sentaurus for power MOSFET design. Are their design's resultant layout compatible with GDSII? Can Cadence import them?

    Hi,

    you get these power MOS cells from your foundry as part of the PDK, if they are offered.

    1. You can't generalize these kind of devices so we don't have generic cells for them.

    2. If it's gds you can import it. Don't know the tool so I can't  say anything about it output formats.

    Kind regards,

    Marc

    There are certainly people who both use Power MOSFETs and design Power MOSFETS and IGBT devices using Virtuoso. Whether they are in an PDK depends on the foundry themselves; it would typically depend if that process is well-suited to such devices (often this would be in high voltage PDKs rather than standard CMOS PDKs).

    I've seen presentations at CDNLIve events on analysis of Power MOSFETS (you'd need to do some searching to find them). Maybe that would help.

    Regards,

    Andrew
