CI: Check repo for YosysHQ specific jobs 
Prevents unintended bumps on the flake.lock and Yosys version on forks (provided the forks synchronize their main after this gets merged).
Update version.yml to use the same style of `if` on the job, rather than on specific actions.
Wheels will still build as a cron job, but won't try to upload if it's a fork.

Jannis Harder 79e05a195d verilog: Bufnorm cell backend and frontend support 
This makes the Verilog backend handle the $connect and $input_port
cells. This represents the undirected $connect cell using the `tran`
primitive, so we also extend the frontend to support this.

Jannis Harder 4f239b536b abc_new: Hide buffered 'z drivers from read/write_xaiger2 
With the updated bufnorm code, buffered 'z drivers are used as anchor
points for undirected connections. These are currently not supported by
read/write_xaiger2, so we temporarily replace those by roughly
equivalent $tribuf cells which will be handled as blackboxes that
properly roundtrip through the xaiger2 front and backend.

Jannis Harder 47b3ee8c8b write_aiger2: Ignore the $input_port cell during indexing. 
The $input_port cell is added by the bufnorm code to simplify handling
of input ports for new code that uses bufnorm, but the aiger2 backend
does already handle input ports separately, so we just ignore those.

Jannis Harder 4918f37be3 write_aiger2: Treat inout ports as output ports 
With the previous bufnorm implementation inout ports were not supported
at all, so this didn't matter, but with the new bufnorm implementation
they need to be treated as output ports.

Jannis Harder 5f79a6e868 Clean up $buf with 'z inputs, $input_port and $connect cells 
This ensures that entering and leaving bufnorm followed by `opt_clean`
is equivalent to just running `opt_clean`.

Also make sure that 'z-$buf cells get techmapped in a compatible way.

Jannis Harder d88d6fce87 kernel: Rewrite bufNormalize 
This is a complete rewrite of the RTLIL-kernel-side bufnorm code. This
is done to support inout ports and undirected connections as well as to
allow removal of cells while in bufnorm mode.

This doesn't yet update the (experimental) `bufnorm` pass, so to
manually test the new kernel functionality, it is important to only use
`bufnorm -update` and `bufnorm -reset` which rely entirely on the kernel
functionality. Other modes of the `bufnorm` pass may still fail in the
presence of inout ports or undirected connections.

Merge pull request #5316 from rocallahan/cleanup-Const 
Cleanup `RTLIL::Const`
 2025-09-16 10:47:29 +02:00
Robert O'Callahan fee2b8992c Stop using `mutable` in `Const`. 
Now that we only call `bitvectorize()` in non-const methods, we can move the casting-away-const to only happen
in `bitvectorize()`, which is deprecated so only some plugins (maybe) are using it.

This means `const` `Const` methods don't change the underlying data, which means
they'll be safe to use from multiple threads if/when we want to do that.
