Let me suggest that generating the "numbering" might be
better off as a separate exercise divorced from the hierarchy.
Like, determine the "placement grid" for texts, make a routine
that indexes content along with setpping coor…
This looks more like a layertable, I like it. Probably a better
thing for PDK which wants to control what layers are and aren't
picked up from a layout (no auto-add or multiple entries sharing
layer & purpose generated by opening a file).
Are …
One neat thing about Brand X texts is the "draftingP"
property option, which will cause a label to always show
right side up (horizontal) or top side to the left (vertical)
regardless of axis flip / rotate stackup through the
hierarchy o…
If you know -why- the device is "faulty" then I'd presume
you could write a regular DRC rule to highlight the feature.
Of course there are many ways to die, and you may find
that this will "churn" your DRC deck ongoing as disc…
I think about Partial-Select and that selecting a single vertex
might be able to deliver the nearest-neighbor coords somehow,
to figure the angle of it?
I have a question about this:
(Quote)
This would seem to preclude a central reference library, or users
would have to copy local (not happy-making for those who manage).
So...
* can a symbolic link in ~/.klayout/libraries work? See remark about …
$20/hr? How Wal-Mart of you. A professional IC layout person
probably sees 5X that. My lawn dude gets $30. Of course he's
got a mower to feed.
So probably depending on the kindness of strangers. Might
start at the start and declare your approach,…
I do analog ICs (if I'm asked to do digital, it gets done
transistor level and SPICE verification). I never use a
SPICE deck to drive layout, schematic speaks to me
and I lay out from that view. A custom SPICE model
set for LVS (dropping all para…
In digital synthesis you really have two goals - functional
hookup, and timing closure. The P&R tool will grind until
it "makes it so" (or fails). The available values for components
are limited and can only be chosen-between.
Analog …
I would expect that Skywater would have instructions if
Skywater in fact supports a Windows environment. But
that is not to be assumed. Ask them straight out. I think
I've seen there are discussion forums specifically for the
Skywater open source …
The people with large test cases might be able to
"strategically mung the design" such that it's of no
value or threat, but still a useful challenge. If they
wanted to help.
I believe that File>Import>Other_Files_Into_Current from
another GDS file" will "uniquify" duplicate names encountered
during the import, if you use the menu command.
Debian / Ubuntu package manager ought to respond to
a left-double-click. If you have the right permissions and
are set up right for "associate with" and so on. Or try
right click and look at options presented.
What I'm trying to do is arrange my .lyp for least "go
find" and clutter, hoping someday to have one that
can be left alone. That's the only "Cadence-ness" I
am interested in - to have my PDK act consistently
wherever it gets ins…
I would recommend updating to latest, just so you don't
have -that- as an overhanging question every single time.
But I have gathered that the Skywater PDK is over-elaborate
and they chose their own adventure - klayout is the tool, but
the hand wor…
That's not a screenshot. It's an image export. A screen shot
would have the X*Y pixels of your display.
Maybe you want to size down to "what works" and combine
those "tiles" in some high-memory-limit graphics editor. If
such a…
I have a question about key-bindings. Maybe two.
* Can a key be bound to a "macro"?
* Can a key be bound to a chain of singlet commands, short of
"macro-izing", by some syntax (like command;command )?
I also recall there was a…
ctrl-D = Descend into a selected instance
ctrl-A = Ascend from an EIP to previous level
There are settings for how the context above /
below are displayed which might affect the "in
place" appearance.
I find GitHub baffling and don't think I've ever found
what I'm looking for, there. I always took the latest off
either SourceForge or the klayout site "Get" links. As
long as those have good latest / greatest, GitHub can
disappear for a…
At that link I see a short wall of ASCII text, looks like
links and some sort of gibberish tags mashed up but
I would have thought a .php ought to have some
"action" to it?
But I don't know from RSS, just that clicking a link
usually h…
It's not just display, it's also your starting position in the hierarchy
or a branch of it (or some cell that doesn't even have a place in the
topcell's hierarchy, so you could not navigate through Ascend / Descend).
Certain other Cell window ope…
LVS works after the fact on its own database derived by logic
from the polygon layout.
GDSII doesn't know from named nets.
What you are asking for is analog layout synthesis and that is
something that's always "coming soon" (for $$$$$$)…
Github is a briar patch I've never been able to navigate. Hate it.
It is plainly not for the casual software-snarfer. I always end up
seeking and finding what I want on the developer's pages or the
forum links, after getting lost in the basement.

Tub = bulk andnot dti
As you say there is no global psub and all transistor terminals
are connected explicitly.
However use-models for PDSOI vary. On the same flow, I have
seen tub-per-device (which we struggled to do verification on,

I share your concern about "doing stuff implicitly" and my
off-the-top recommendation is to make it default to "nope!"
and require users to override willfully. Then at least the tool
is blameless. Guard against "cruft"…
I am still bothered by all the passed-in connectivity (like
"Vss$1" and thinking this makes a net that somebody thinks
should be Vss, but somebody else says "huh?".
For printable characters you really have to stay with "fat stick"
style or you'll violate groundrules on the little cutesy features of
(say) a Times New Roman font. In my experience you're lucky
to get "big and little". I have …
It might help somebody later if you described what you found.
Like was it an import side or an export side problem? Or that
the "circles" were actually cells and display depth too shallow?
