Warning: Ignoring boxed module $paramod\ALU\ALU_MODE=s32'00000000000000000000000000000010

I upgraded to the latest yosys version and now getting a new warning:

Warning: Ignoring boxed module $paramod\ALU\ALU_MODE=s32'00000000000000000000000000000010

Source files in this directory https://github.com/FPGAwars/apio-examples/tree/master/examples/sipeed-tang-nano-9k/blinky-sv

Command line:

yosys -p "synth_gowin -top blinky -json hardware.json" -q blinky.sv

The warning doesn't seem to be directly related to my simple code. Any idea what the problem is?

The warning is related to a recent change in how boxes are handled (#4768); a number of commands were silently ignoring boxes even if the user explicitly requested them, so it now raises a warning. For some cases (like this) it's less "tell the user something went wrong" and more "hope somebody reports this so that we can find all the bits of code that still need updating", so thanks!

@KrystalDelusion, should I file an issue or is this post sufficient?

[KrystalDelusion]

This is fine 🙂

(If you want to file an issue so that you get notified when it's resolved that is also fine)
