mithroEdalize now supports using containerized EDA tools. Thanks to @carlosedp  for kicking this off. Will do a write-up shortly but quick howto for building SERV using dockerized EDA tools from @unaimarcor et. al. follows here.02:32

umarcorOverall, asciidoctor has several nice plugins for generating single page HTML and PDFs. I find it much better than Sphinx in that regard.13:27
umarcorHowever, composition of HTML sites with multiple pages, and/or cross-referencing multiple sites is not straightforward. Sphinx/intersphinx are better at that.13:28
*** yuumei has joined #symbiflow14:49
yuumeiHello, I'm trying to build the counter_test example for my development board netv2 (xc7a100tfgg484-2), I'm running in to a problem where the build is looking for pinmap.csv:15:01
yuumeiprjxray_create_ioplace.py: error: argument --map/-m/-M: can't open '/home/ash/github/symbiflow/xc7/install/share/symbiflow/arch/xc7a100t_test/xc7a100tfgg484-2/pinmap.csv': [Errno 2] No such file or directory: '/home/ash/github/symbiflow/xc7/install/share/symbiflow/arch/xc7a100t_test/xc7a100tfgg484-2/pinmap.csv'15:01
yuumeiI guess xc7a100tfgg484-2 isn't included in the downloadable toolchain, I tried looking for where this file is generated but I'm having difficulty. If I build symbiflow-arch-defs with "make all_arty100t-full_bin" will that generate the pinmap.csv files if I modify xc/xc7/boards.cmake to include my specific part?15:01
sf-slack<acomodi> yummei: indeed it is generated in the symbiflow-arch-defs flow. A way to generate that is as you say, by adding a board to boards.cmake, and than adding an additional test in the `counter` tests under `xc/xc7/tests/` , similarly to the tests already present15:04

bryce_I feel like I'm really missing something. I'm trying to install symbiflow, but I'm getting absolutely nowhere. How do I make it so that I can just open a terminal and type something analogous to "gcc code.c" and have it synthesize? Following the instructions in the examples literally is not working and I have no idea how to even begin to troubleshoot this stuff, which seems to involve a lot of virtual environments and complicated build21:57
bryce_systems.21:57
litghostWhat instructions where you following?21:58
bryce_https://github.com/SymbiFlow/symbiflow-examples/tree/master/xc7/counter_test21:59
bryce_https://symbiflow.readthedocs.io/projects/arch-defs/en/latest/getting-started.html  I also tried this one, which did a ton of stuff but then had some kind of opaque (no identifiable error) failure to actually program the board.21:59
litghostSo we literally execute the instructions here: https://github.com/SymbiFlow/symbiflow-examples/runs/176558896821:59
tpbTitle: Getting Started symbiflow-arch-defs 0.1 documentation (at symbiflow.readthedocs.io)21:59
litghostWe literally copy the instructions from the README and execute it in CI22:00
litghostYou can follow along line by line with the Github Actions invocation22:00
bryce_I'll try that22:00
litghostStarting in the "Install Symbiflow Toolchain" block22:01
litghostThere is also instructions for running the CI infrastructure locally: https://github.com/SymbiFlow/symbiflow-examples#running-ci-locally22:01
bryce_Sorry, what is "CI"?22:02
litghost"Continuous Integration"22:02
bryce_ahh22:02
litghostWe run the instructions we publish through GH actions, which are just some machines somewhere, and try to see if those instructions are good are not22:02

-_whitenotifier-5- [symbiflow-examples] litghost opened issue #132: Should run GH actions check nightly - https://git.io/JYtVe22:04
litghostI do see that the check last ran 10 days ago, so it is possible that something broke between now and then22:04
bryce_Sorry, I haven't used this feature of github before; that page you linked me to (https://github.com/SymbiFlow/symbiflow-examples/runs/1765588968) seems to show the results of various commands, but I don't see what commands are being run.22:07
litghostLook at the "+ "22:07
litghostThat is the command22:07
bryce_I don't see a +... I have a chevron symbol that expands the headings like "Set up VM" and then I see a number, a timestamp, some text and a duration. None of the things do anything when I click them. Sorry I'm not seeing it.22:09

litghostSo command there is "apt update -y"?22:10

yuumeiI have generated a pinmap.csv (Copied from my new netv2_pinmap.csv which I'm guessing is ok) but now I can't seem to find tilegrid.json, is that file generated by prjxray? My "make db-prepare-artix7" does not seem to generate it22:37
litghostI don't think you need to run prjxray for tilegrid right now, unless you are adding new tiles22:38
litghosthttps://github.com/SymbiFlow/prjxray-db/tree/master/artix722:38
litghostShould have tile grids for all of the artix7 parts available in WebPack22:38
*** rvalles has quit IRC22:38
yuumeiAlthough there is a "./database/artix7/xc7a100t/tilegrid.json" is that safe to copy to the specific symbiflow/prjxray-db/artix7/xc7a100tfgg484-2/tilegrid.json22:39
*** rvalles has joined #symbiflow22:39
yuumeiThere is a tilegrid.json in xc7a100t, I guess I can copy to the specific IC folder22:40
litghostThat shouldn't be needed anymore22:41
litghostWe refactored the file structure to avoid the redundancy22:42
litghosthttps://github.com/SymbiFlow/prjxray-db/blob/c0ac6c19286e31205d2b7c0a5c7ba25fba8cb13e/artix7/mapping/parts.yaml#L21-L2422:42
litghostSo "parts.yaml" maps the part to the device, and we have https://github.com/SymbiFlow/prjxray-db/blob/master/artix7/mapping/devices.yaml to map the device to the fabric22:43
yuumeiHm.. I have those changes22:43
litghostHow/where did your prjxray python library come from?22:44
litghostMight be out of date22:44
yuumeiI'm using "option 1" from step 5 https://github.com/SymbiFlow/prjxray22:46
yuumeiI copied the file over and it worked, I'll see if I can find the problem22:48
yuumei*with my setup22:49
yuumeiThanks!22:49

litghostShould be recent then23:15
litghostAssuming you checked out the most recent version of prjxray23:16

litghostSo it is recent, but not that recent of a change23:17
