user outputs

io_out

to the gpio pads need the corresponding

io_oeb

to be low. Otherwise the output is disabled. The oeb check is for this.

can I connecte io_oeb to LA pins to make it configurable?instead of making it permanently as output?

That sounds like a valid solution. However, with a direct connection, the OEB check probably still fails. Can you run your LA pin through a buffer before

io_oeb

?

@Mitch Bailey I am also getting an FEOL error but when I try to open the mask in layout the file gives error,so I am not sure how to debug it

@samarth jain I think that’s due to an older version of

klayout

. Do you have

0.27

or

0.28

?
