What layout are you looking at? The result that you show looks like the initial result from Openlane, which (because Openlane doesn't know how to generate wide signal traces for analog) gets deleted and re-routed by hand.

This is layout in caravan.gds.gz on caravel repo. Idk if there is other variant of this file. Myabe generated after I integrate my user project one, will have proper routing. Ignore this thread then. Sorry for bothering

@User: The top level layout is always constructed by magic from constituent parts. I constantly complain that large and unused files are left lying around the repository. The caravan.gds is one of those. Even worse that it's an incorrect layout.

Understood. One question then, where are the caravan gds that are hand routed? I am trying to measure some parameters from it.

In

mag/caravan.mag

. Once you have assembled a project with

make truck

, a GDS file will be generated for it. Otherwise, you can read the layout in magic and run

gds write caravan

(there is probably a Makefile recipe for that, too).
