sf-slack<timo.callahan> In symbiflow-arch-defs, after redoing "make env", I redid "make all_conda", and suddently got a ton of package conflicts.   Any idea what I could have done to mess up my environment, and how to clean it up?    I guess I'll just do a make clean and rebuild overnight.  But a higher level question -- when exactly do I need to do "make all_conda" ?    Thanks!07:23

HackerFooIt happens often to me. `rm -rf build/env` and try again.14:07

HackerFooshapr: I had one at one point, but it's hard to keep CMake from using Conda.17:48
HackerFooMaybe I'll try again. It's a pain, because Python.17:50
HackerFooI have a shell.nix for VTR though: https://github.com/verilog-to-routing/vtr-verilog-to-routing/blob/master/dev/nix/shell.nix17:52

HackerFooThis is what I've used, but it's kind of a mess: https://gist.github.com/HackerFoo/558c0b60e5ff75db808d8567c53734e117:59

HackerFooThe problem is that dependencies often change. Maybe I can write something that parses CMakeLists.txt, but I'd rather not rely on Conda, so I need to convert the Conda package names to git revisions.18:07
HackerFooI've been putting it off, hoping that the situation will get better as things stabilize.18:09

sf-slack<timo.callahan> Yeah, I guess we were co-authors on a paper, although in our group at Berkeley we mostly worked on different stuff.21:10
sf-slack<timo.callahan> Anyway thanks for the Zynq PR.   I was thinking of picking up a Zynq board myself...21:11
andrewb1999timo.callahan: No problem!  Working on cleaning up my symibflow-arch-defs changes for the 7020 and will try to get a PR in for that soon.21:29
andrewb1999Today I was able to upload a few different test bitstreams without issue21:30
sf-slack<timo.callahan> andrewb1999: Great!  I'm currently trying to put a Symbiflow-compiled, Linux-capable Litex design on an xc7a100t, which we are just adding support for now.22:17
