04/18/2021, 12:52 AMInstalled openlane and ran the spm test case. The GDS looks like the attached png. Is this correct? Those protruding pieces look odd.

04/19/2021, 1:16 PMIt looks wrong to me in a way I've never seen before
did you exactly follow the install instructions?
and what tag? I wouldn't try with the latest develop. Use something more stable like mpw-one-c

J. Scott Elder
04/19/2021, 1:18 PMI followed the instructions on github and the make and test ran clean.
i ran on ubuntu 20.04

Matt Venn
04/19/2021, 1:19 PMshould look like this:
what tag of the tools?
can you post the gds here?
j
J. Scott Elder
04/19/2021, 1:20 PMtag?
m
Matt Venn
04/19/2021, 1:22 PMlatest release is tagged 0.7
I wouldn't use anythign above that unless you know what you're doing or are developing

J. Scott Elder
04/19/2021, 1:23 PMHere's the gds...
I followed the instructions here: https://github.com/efabless/openlane

Matt Venn
04/19/2021, 1:24 PMyeah that GDS is totally broken
j
J. Scott Elder
04/19/2021, 1:25 PMthat's what i thought.

Matt Venn
04/19/2021, 1:25 PMI would delete it all, check it out at rc7 and rebuild/install

J. Scott Elder
04/19/2021, 1:25 PMlooked nothing like what Mohammed K. posted on youtube.

@Amr Gouhar @Ahmed Ghazy we should probably make it much clearer on the top level README that people should check out the latest stable release, not try to build from master
j
J. Scott Elder
04/19/2021, 1:30 PMwell, that brings up another point. there is a statement to do just that, but the link us broken!

Matt Venn
04/19/2021, 1:36 PMI remember talking about this with Ahmed a while back. It should definitely be fixed!
@J. Scott Elder can you clarify something for me
did you follow this instruction:
Copy code
git clone <https://github.com/efabless/openlane.git> --branch v0.12?
j
J. Scott Elder
04/19/2021, 1:41 PMhere is the link on the openlane github: https://github.com/efabless/openlane/tree/release-0.x
m
Matt Venn
04/19/2021, 1:41 PMyeah, I'm opening an issue and I want to know what tag you were on to get that result
so did you clone the repo with --branch v0.12
?
j
J. Scott Elder
04/19/2021, 1:42 PMi believe i did v0.12, but i am checking.
yes, i did 0.12, that was in the instructions.
m
Matt Venn
04/19/2021, 1:43 PMok thanks
j
J. Scott Elder
04/19/2021, 1:44 PMthe instructions on the same page where the "latest version" link is broken. goes to a 404 page.
m
Matt Venn
04/19/2021, 1:44 PMI would try --branch v0.7
j
J. Scott Elder
04/19/2021, 1:44 PMgo here" to quick start section - https://github.com/efabless/openlane

Matt Venn
04/19/2021, 1:45 PMyeah, I've just opened an issue to make a note of it: https://github.com/efabless/openlane/issues/295

04/20/2021, 12:51 AMFound the problem, Matt. I viewed the GDS from the Klayout results folder. When I viewed the GDS from the Magic results folder, I get your picture. I think when the GDS is built for Klayout there is a problem. I used Klayout to view the Magic GDS just fine. So it's not Klayout. See attached image.

04/20/2021, 8:12 AMI didn't even know there were 2 GDS files produced. I haven't tried rc0.12 yet tho.
glad you sorted it
