what does
`% ext2spice
Error:  Ran out of space for device types!` mean during extraction?

It means your version of magic is out of date, maybe?  I fixed this problem (or thought I did) a few revisions back.

ah ok, thanks. To upgrade I'll need to build from your repo, or is there a distribution?

ah nvm I realised I built from source last time so I can just pull changes and redo those steps (with a lot less worrying about prereqs this time around, fortunately)

that did the job perfectly, thank you :slightly_smiling_face:

Maybe I spoke a little too soon: when extracted I got the dimensions
```ad=0p pd=0u as=0p ps=0u w=6.5e+06u l=150000u```

however it seems to simulate ok, so I'm not sure if I need to worry about it

That's correct, what's your concern?  In magic, source/drain areas and perimeters are calculated per net and are lumped on the first device found.  If you want them distributed across devices, use "ext2spice -d", but it should not make a difference to simulation (however, I am not aware of all the ways BSIM parameters work, so that might not necessarily be true).
