Conda-forge and Viper

[curtisma]

Have you considered submitting these recipes to Conda-forge rather than having your own channel? It could handle all the build infrastructure and the recipes would be maintained by the tool owners and/or anyone else interested in helping maintain them. They also have a well documented process for creating new recipes which could make it easier to support new tools.

I've proposed this approach as part of the Viper circuit design environment and viper-forge.

Sounds like you just invented the same thing I did --> bit.ly/edda-conda-eda-spec

[curtisma]

haha, cool, want to work together?

[curtisma]

I work on analog & RF IC design but there should be a lot of overlap.

[mithro]

Yes please!

We are concentrating our packaging efforts under the https://github.com/hdl organization.

There are multiple packaging efforts;

• conda
• containers
• Termux (android)
• mingw (Windows)
• etc

[mithro]

BTW Have you seen Google's SkyWater open source PDK (https://github.com/google/skywater-pdk) and the associated no-cost shuttle program for open source designs @ efabless.com?

[mithro]

It seems like our work is pretty complimentary too! Our focus has been heavily on the CPU / digital (starting with FPGAs + cross compilers) while your focus has been more on the analog side.

[mithro]

@proppy and myself have also discussed the idea of having both our own package channel and also have parallel packages in conda-forge too.

[curtisma]

Yeah, I've heard about the Sky water shuttles. I've been considering putting together and submitting a design.

What's the best way to collaborate? Do you want to have an online meeting or discuss on one of our GitHub discussion boards perhaps?

[proppy]

@curtisma I just happen to have started a PR to add a subset of those package to conda-forge as part of #193, see conda-forge/staged-recipes#18295

[curtisma]

@proppy Ok, awesome, do you need help with it?

[proppy]

@curtisma rebased the PR and it nows pass the CI for linux: conda-forge/staged-recipes#18295, do you want to take a look before I ping the conda-forge folks about it?

[curtisma]

Sure, I can take a look tonight. That's what I had guessed when I saw it previously

[proppy]

magic got in! https://github.com/conda-forge/magic-feedstock

[curtisma]

Awesome, thanks @proppy ! I'll try it out this evening.

[curtisma]

@proppy Now we need to package some type of schematic editor such as xcircuit.

[mithro]

Do you have Xyce / ngspice? KLayout would be important too...

[curtisma]

I just tested it out with the simple environment file below and it starts up at least:

# opensource.yml 
# Open source Viper IC design environment
name: open_source
channels:
  - conda-forge
  - defaults
dependencies:
  - magic

[curtisma]

Yeah, it's on my to-do list.
I've put together a list of packages we'd like available initially for an open source IC design conda environment:

cascode-labs/viper-forge#1

Can you think of any others that should be added?

[proppy]

@mithro https://anaconda.org/conda-forge/ngspice :)
