Compare the collected data against the data found in the SKY130 PDK

[mithro]

It would be great to compare the raw data found in this repository against the data found in the SKY130 PDK found at http://github.com/google/skywater-pdk

Hi, Markus from the DMT/semimod team here (https://gitlab.com/dmt-development/dmt-core).
This is something that is straightforward to do with our existing open-source tools.

We have created an issue
and will do this task in the coming weeks. Thanks for sharing your data open-source!

@metroid120 - We would love to include this stuff in this repository, so please do send pull requests!

In order to compare the measurement data against simulations, we also must know the measurement temperature. I would assume, it was measured at regular 300K. Can you please confirm this @mithro ?

Yes it is room temp.

I had some time today to play a little and install the skywater130 pdk using the great open-pdks repository. I tried to get the models running in combination with DMT. This would allow an easy automation of all the comparisons you need.

A first hacked script looks like this:
check_skywater130.txt

The resulting plots:
IDVD.pdf
IDVG.pdf

Does this help you?
If you have any kind of feedback or direct feature requests, feel free to directly raise an issue in the DMT repository.

They look cool but I'm no circuit designer or PDK developer :-)

Maybe share them on the open-source-silicon.dev slack channel and see what other people think?

Dear all, we now have made a small separate repo that shows how to read, analyze and compare the measurement data in Python using our open-source tool DMT. You can find it here:

Hope it is useful :)
