This uses the environment variable `YOSYS_PLUGIN_PATH` to provide multiple colon-delimited search paths for native plugins in a similar manner to `PATH` for executables and `PYTHONPATH` for Python modules.
This addresses https://github.com/YosysHQ/yosys/issues/2545, allowing Yosys to be better packaged in non-FHS environments such as Nix.
Replaces double quotes on problematic regex strings (mostly ones that have escape sequences that are easier to preserve in single quotes). Necessitates also changing single quotes to `.`, i.e match any.
For some (mostly ones that only have a single escaped character, or were using `\.` to match a literal fullstop) keep the double quotes and fix the regex instead.
This fixes some edge cases the previous version didn't handle properly
by simplifying the logic of determining directly driven wires and
representatives to use as buffer inputs.
Was previously the number of proposed renames, but since renames can be skipped this causes the final count to differ from the number of actually renamed objects.
Check counts in `tests/various/autoname.ys`.
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.
* When used with -tempinduct mode, -seq <N> causes assertions to be
ignored in the first N steps. While this has uses for reset modelling,
for these test cases it is unnecessary and could lead to failures
slipping through uncaught
Modify `cutpoint_blackbox.ys` to check that parameters on blackbox modules are maintained after the cutpoint.
Also adjusts the test to check that each instance gets the `$anyseq` cell.
