Hi Matthias, Thanks, and sorry for the confusion. I am using a slightly different .lyt file than Laurent, which does have the mappings in it: https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/872b051431ebb04f9def5b9b965b7469a81be38…

in Unsure why LVS is reporting mismatch Comment by rovinski November 2020
Hmm, there seems to be a new issue present in version 0.27, though. With the .lyt file for FreePDK45, it doesn't seem to remap layers from DEF correctly. In version 0.27, there is a giant box on via8 (26/0) placed over the entire design: (Image) …

Hi Laurent, You were right - the version number is important here. I didn't see version 0.27 on the downloads page (https://www.klayout.de/build.html) or GitHub Releases so I did not know it existed! I am seeing a full match with version 0.27. Tha…

🤦‍♂️ I'm not sure how many times I've looked at that and didn't notice the typo. I fixed the reference circuit and everything matches, thanks! As a follow-up question, I have a different inverter INV_X1. The PDK provided the following schematic: .…

Thanks Matthias, that makes sense.

in Performance of Cell.is_top() seems slow? Comment by rovinski May 2020
Hi Matthias, Yes, you are correct. My DEF had many statements in them and I tried to trim it down to just one example, but I dropped the '+' that was needed. I see that this fix made it into the 0.26.4 release. I have run a few different tests usi…

in Support for VIARULE LEF/DEF Constructs Comment by rovinski March 2020
Hi Matthias, Thanks for the response. The reason for the difference in the second image is because I had a typo in the code that generated it (omitted (1.dbu) ). However, that was not the issue as I got the same result of no output. I tried a diff…

in DRC: layer.interacting() doesn't appear to output the interacting layer Comment by rovinski February 2020
This seems like it can be accomplished with space()

in Design Check Rule - minimum distance between paths Comment by rovinski February 2020
Update: I found that the fill utility is accessible from the scripting interface as Cell.fill_region(). I'm surprised it was hard to find, search results really didn't show anything.

in Invoke Fill Tool from Script Comment by rovinski January 2020
Hi Matthias, Sorry to revive such an old thread, but is there any planned support for this? I am investigating KLayout as a tool to script dummy filling designs. If the only way to use the fill utility is through manual input, that would be problem…
