Icarus Verilog support

[Jesus89]

Using toolchain-verilog package requires passing some paths to the binaries iverilog and vvp because it is a local installation:

• IVL: /path/to/toolchain-iverilog/lib/ivl
• VLIB: /path/to/toolchain-iverilog/vlib/system.v (yosys lib compatibility)

Use cases:

• Linux/Darwin:
  • iverilog -B IVL VLIB sources
  • vvp -M IVL source
• Windows:
  • iverilog.exe VLIB sources
  • vvp.exe source

There is a standard way to pass these paths to the builder?

Yes, it's possible. With PlatformIO 3.0 you have full control on PlatformIO. In this case, in main script main.py need to add

from os.path import join

platform = env.PioPlatform()
env.PrependENVPath("PATH", join(platform.get_package_dir("toolchain-verilog ", "lib", "ivl")))

In this case, PlatformIO Core will manage packages using semantic versioning and depended packages will be automatically loaded.

Ok! Thanks for the information.

I granted you with full permissions to this repo. You can work on it without PR.

[Jesus89]

Great. Thanks!

I suppose that correct syntax is:

join(platform.get_package_dir("toolchain-verilog"), "lib", "ivl"))

instead of join(platform.get_package_dir("toolchain-verilog ", "lib", "ivl"))

Also, I can not access to _platform.get_packagedir("toolchain-iverilog") because there is no toolchain-iverilog version in appstate.json although package is installed. Same with toolchain-icestorm.

[ivankravets]

join(platform.get_package_dir("toolchain-verilog"), "lib", "ivl"))

This is correct syntax.

platform.get_package_dir("toolchain-iverilog")

While package isn't installed yet, need to use join(platform.get_package_dir("toolchain-verilog") or "", "lib", "ivl"))

appstate.json

PlatformIO 3.0 doesn't use appstate.json for package registry. It relays on real manifests located in the packages. Please check that toolchain-iverilog has package.json.

[Jesus89]

Yes. It contains the package.json. Just everything reinstalled and it works.
