some DRC rules are different for the 5/6V devices, how can I opt to use the 5/6V rules rather than the 3.3V rules in magic?

I guess you have to rewrite the .tech file to adopt those rules.

@sage walker: The layers for the 5V/6V devices all begin with

mv

(medium voltage, the nomenclature mostly in keeping with sky130 and other processes that have higher voltage implant layers). A 5V nFET, for example, is

poly

over

mvndiff

. You can always create devices from the PDK device generator for magic. Go to the

Devices 1

menu and select

nmos - nMOSFET

, then in the device generator popup window you can select for "Device type" either

nmos_3p3

or

nmos_6p0

. Currently the GF device generator scripts are under-developed, but I have an intern working on that.

Hello Tim, hope you are doing fine We are currently starting to use Magic with GF180, and we are wondering what do you mean when you say that the GF device generators are under developed... is there anything you can share already? I believe @Patricio Carrasco, who's working with us in the chipathon project, could be interested

@Jorge Marin: I have an intern in the Google Summer of Code program who is working on completing the GF device generators for magic. There are already device generators completed for klayout (from Amro Tork).

I see, thanks Will you announce when they are ready? Do you have a target date? Just to know if we can wait for them or proceed with other solutions

It's ongoing. I should be doing updates to open_pdks every week or two.
