How difficult would it be to get

1r1w

generation working with sky130?

You just change 1 rw to 1 w and it won't add the sense amps

The last time I tried that the compiler stopped with an error something like: the size of columns is not a multiple of something...and I just assumed, I was not supposed to that 😄 I'll try to run it again. I probably had set something wrong.

That error would be for a single port memory which requires the columns to be a multiple of 2 (including the replica column)

I see. Makes sense.
