<@757706909351411845> If I want to make changes to the analog simulations, do I PR to the previous RFC or make a new one?

## Seve — 2026-07-25T15:38:02.037000+00:00

Either way is common!

## Seve — 2026-07-25T15:38:17.307000+00:00

Usually if the rfc is new, edit

<@757706909351411845> I split the fix for sample 4 to two parts, I understood part 1 and make the visualization clear, part 1 fixed sample 4's static reachability issue but it doesn't pass yet, 

the PR increased dataset 23 DRC completion by 48%

https://github.com/tscircuit/tscircuit-autorouter/pull/1799

## shibo — 2026-07-31T14:32:51.279000+00:00

the issue is that we failed to detect bga shapes if the component has other pads outside the bga pattern

## shibo — 2026-07-31T14:32:57.019000+00:00

the PR body explains further

## Seve — 2026-07-31T14:53:09.978000+00:00

Sg!

## shibo — 2026-08-01T14:42:26.711000+00:00

<@757706909351411845> fix in repair solver 03, improves DRC pass rate for the kicad dataset 24 from 0% to 20%, I noticed no regressions: https://github.com/tscircuit/tscircuit-autorouter/pull/1810

## Seve — 2026-08-01T17:39:48.817000+00:00

cool

## Seve — 2026-08-01T17:39:50.613000+00:00

nice

## shibo — 2026-08-04T16:46:35.262000+00:00

<@757706909351411845> new sample from OpenAI's dataset passes DRC: https://github.com/tscircuit/tscircuit-autorouter/pull/1902

## shibo — 2026-08-04T16:46:45.881000+00:00

repair 03 fix

## shibo — 2026-08-05T16:57:23.096000+00:00

<@757706909351411845> new sample pass DRC in both OpenAI and kicad datasets: https://github.com/tscircuit/tscircuit-autorouter/pull/1927

## shibo — 2026-08-05T16:57:54.725000+00:00

DRC rate is 25% and 30% respectively

## Seve — 2026-08-05T16:58:16.475000+00:00

*partner datasets 😉

## Seve — 2026-08-05T17:00:17.342000+00:00

yea looks great

## shibo — 2026-08-05T17:00:36.969000+00:00

does that mean now we pass DRC for 1/4 of all boards in the world? 😂

## shibo — 2026-08-05T17:01:19.766000+00:00

now I want to add a kicad dataset that has 10 of the hardest boards from kicad, just to humble myself

## shibo — 2026-08-05T17:03:19.556000+00:00

are kicad boards a good sample of boards used in the real world? or are the hard boards for huge companies that do advanced stuff always private?

## shibo — 2026-08-05T18:01:40.696000+00:00

<@757706909351411845> wdyt?

## Seve — 2026-08-05T19:09:09.162000+00:00

🤷

## Seve — 2026-08-05T19:09:19.694000+00:00

kicad isn't used as much by professional companies

## Seve — 2026-08-05T19:09:22.765000+00:00

Altium is more used

## Seve — 2026-08-05T19:09:28.490000+00:00

the TI reference designs are all altium

## shibo — 2026-08-05T20:40:29.397000+00:00

good to know

## shibo — 2026-08-06T04:25:55.326000+00:00

<@757706909351411845> repair 03 fix, new sample passes DRC: https://github.com/tscircuit/tscircuit-autorouter/pull/1937

## shibo — 2026-08-06T09:42:12.444000+00:00

<@757706909351411845> you said how could we know it's not just from increasing iterations, i kept only the iteration increase and nothing was fix, we also have a repro in the repair 03 pr that proves the fix

## shibo — 2026-08-06T16:18:09.925000+00:00

<@757706909351411845> new sample passes DRC: https://github.com/tscircuit/tscircuit-autorouter/pull/1941

## shibo — 2026-08-07T14:39:01.568000+00:00

<@757706909351411845> no new samples pass but tens of DRC issues are fixed: https://github.com/tscircuit/tscircuit-autorouter/pull/1968

## shibo — 2026-08-07T16:39:28.932000+00:00

<@757706909351411845> fixed another issue, again no new samples pass: https://github.com/tscircuit/tscircuit-autorouter/pull/1950

## Seve — 2026-08-07T16:49:03.571000+00:00

Nice
