Are there setup options which could make the "need to de-assert" instead be default-to? Or is it a thing that one line in a startup script (?) can sort?
-
There's a lot to antenna checks, comprehending at each level of lithography what is and is not exposed-to, protected-from. I have a pretty good gut understanding and roughly zero coding skill / interest, if OP wants the bottom- up perspective or…
-
I am thinking maybe what's wanted is a bit more documentation, and/or curated examples of a "setup code section". I find that one good template and text mode, can be far more efficient than an endless series of GUI kickoffs (especially if …

Hi Matthias, Wonder if it's to do with 4K panel vs printer but seems to be confined to text scaling, not objects. Maybe in the text rendering, "scaling stack" of DBU to pixel to DPI at those particular objects (probably having their own …
-
This suggests to me, maybe some utility which could scrape through "bloaty" database formats and cell by cell, bottom up, "pack down" cells to use those least- memory "styles"? Proving all that, lossless and error free…

Couldn't figure out how to show the printed output, other than this:

Maybe one only wants to "snap to origin" (texts are crappy that way, very finicky to select / move without deselect, etc.). There may be (should be used) an "extents box" that is selectable, I've opened up the origin-aperture to…
-
Many kits use blocking and identifying purpose layers to steer DRC and extraction. There needs to be the logical use of those polygons of course. Every "real" layer of interest would be "ANDNOT"ed with its exclusion layer to ma…

I would like to see (or be led to) more info on menu modifications for aspiring "power users". Something tutorial-like that wasn't a video, maybe?
-
Another thing (besides my general loathing of "strokes" on touchpad machines) - contracted to a client whose IT enforces short "go to sleep" cycles, I use one of those "mouse jigglers" to keep the session from res…

Re not liking SPICE netlist format: What about netgen, the other LVS engine that one of the earlier "E-ASIC" type consortia had in its CAD constellation (I forget the name now, Tim Edwards was in on it)? MAGIC, netgen and Xcircuit and w…

"Creating" the .lyp is just (with an imported layout) File>Save Layers (or some such - away from the machines with klayout at present). Making it all pretty and orderly is a hand editing job, using either the layer window context / ri…
-
I don't know about modern mask fab algorithms or nuthin', but my gut says those would be better able to deal with more, smaller, less complex polygons / shapes than the kinds that require klayout, and maybe mask fracture differently, to think up its…

Many orgs seem to have a habit of calling the top cell "TopCell". When you do part after part after part, you can stand to lose a few repetitive questions. If you get to name the baby, then you might develop a habit that saves thought.…

We used to stick to 45 snap and groundrule compliant widths. Prettier brings more DRC trouble.
-
I don't know specifically, was unaware that XFAB had open source PDKs. But I encourage you to check on the going-forward availability of any XFAB flow you pick, because some seem to have gone bye-bye according to a client who's used them.
-
Why not go ahead and pull latest-latest from the repository? Then all you need to know is "latest version of dependencies, too". Random salad brings mystery chunks.

There is no such thing as a true circle in a Cartesian step-grid system. It's all vectors or pixels and not the ideal. I always up the vertex-count on drawn circular features using the primitive. Kinda fond of 72 as it's got so many clean-symmetry …

Maybe if every layer of the path-resolution was "bite sized" as a shall variable, the user might find a way do this abstraction. Personally I like full hard paths nobody can mess with, but I am not subject to CAD management or its dic…
-
I'd take this a step further and maybe look at making a "CAD administration for non-sysadmins" cookbook. We all want to jump ahead to the fun, but running the Zamboni first (and maybe at half time) does improve the game-play. If it spr…
-
As long as full path works, I'm good.

When I imported a R12 .dxf file I got named layers with no evident numbering? Tag-along "technology" layers from last chip DB were still there with names and numbers both. I imagine there's utility for some script, that could parse DXF f…
-
A script would have to be "taught" by someone or something that "knows" the meaning of each layerNum. A skilled layout or design engineer would have some amount of the required "gut". A PDK layer table of course woul…

I sense that the question is about the cursor itself and whether its movement can be made "steppy". I believe the cursor movement is a separate thing from the behavior of objects being moved or made, by it. Those commands are subject …

Personally I use .png and TIFF is about as fat as an image file can be. But I only do interactive. That all seems orderly and works fine (though I could ask for "persistent background image" to not have to re-attach every time). What I do…
-
It would be occasionally useful, if the Cells window offered a right-click "print this puppy" option (following the choice of display-form). To copy-buffer or to chosen-file.

Seems to me that a literal, polygon for polygon translation ought to be an option. I'd guess that the problem is vectors that are "loose", with no "bundle" to decide which merge and which do not in subsequent steps? Perhaps thi…
-
Does the install bundle not state which dependencies and versions? If not, then you should put that question to the maintainers. However the error I see, looks more like maybe a PCell:code_pile sync / content problem, it seems a bit of code h…

Didn't ctrl-S, ctrl-Q use to have some low level UNIX function, like stop / start TTY scrolling? Might be some unintended "overlaps" there....
