00:50 <Bird|ub3rghosted> azonenberg, I recall there being an EDA-tool-of-sorts called Electric (originally written in Smalltalk, but ported to Java) that could basically do polygon level layout, and I *think* it may have been open-source (certainly accessible to a mere mortal like me)

00:50 <azonenberg> Bird|ub3rghosted: Magic is the go-to tool for this kind of stuff now AFAIK

00:50 <azonenberg> Which is open

00:51 <azonenberg> there's also KLayout but i think it's a lot less sophisticated (although it's newer and the UI is prettier)

01:12 <_whitenotifier-a> [scopehal] azonenberg 6cab4df - DeEmbedFilter: flush cached parameters when switching from one S-parameter path to another. Also rescale plot bounds.

01:12 <_whitenotifier-a> [scopehal] azonenberg 3e4ae46 - Added TDRFilter, can output either reflection coefficient or impedance. Fixes #110.

01:12 <_whitenotifier-a> [scopehal] azonenberg closed issue #110: Add TDR display filter for showing traces in Ohms - https://git.io/Jf8AK

01:38 <azonenberg> glscopeclient TDR transform on 26 GHz VNA data, vs actual 16 GHz TDR measurement

01:53 <_whitenotifier-a> [scopehal] azonenberg opened issue #496: TouchstoneParser: support .s1p files so we can do TDR emulation with single-port measurements - https://git.io/JZch9

03:03 <_whitenotifier-a> [scopehal-apps] azonenberg pushed 1 commit to master [+0/-0/±1] https://git.io/JZCOP

03:03 <_whitenotifier-a> [scopehal-apps] azonenberg 89f5b4a - Updated to latest scopehal

06:50 <azonenberg> TFW you discover the sim run you had going all day had a bad port configuration and is completely invalid

13:10 <azonenberg> https://pbs.twimg.com/media/E3hah7uWQAgUNmh?format=jpg&name=large LOL check out that last sentence

13:22 <GenTooMan> well at least they have a sense of humour.

14:30 <someone--else> by any chance, is there anything about implementing TDR deconvolution to get a true impedance curve when multiple reflections are present?
