Jannis Harder f2c531e65f verilog_backend: Do not run bmuxmap or demuxmap in -noexpr mode. 2022-11-30 18:24:35 +01:00

Jannis Harder 99163fb822 simlib: Use optional SIMLIB_GLOBAL_CLOCK to define a global clock signal 2022-11-30 18:24:35 +01:00
Jannis Harder 605d127517 simlib: Silence iverilog warning for `$lut` 
iverilog complains about implicitly truncating LUT when connecting it to
the `$bmux` A input. This explicitly truncates it to avoid that warning
without changing the behaviour otherwise.

Jannis Harder 39ac113402 simlib: Fix wide $bmux and avoid iverilog warnings 2022-11-30 18:24:35 +01:00
Jannis Harder b982ab4f59 satgen, simlib: Consistent x-propagation for `$pmux` cells 
This updates satgen and simlib to use a `$pmux` model where the output
is fully X when the S input is not all zero or one-hot with no x bits.

Jannis Harder 661fa5ff92 simplemap: Map `$xnor` to `$_XNOR_` cells 
The previous mapping to `$_XOR_` and `$_NOT_` predates the addition of
the `$_XNOR_` cell.
