Charlotte 4e94f62116 simlib: blackbox `$print` cell 
It's possible to `generate` the appropriate always blocks per the
triggers, but unlikely to be worth parsing the RTLIL \FORMAT parameter.

Jannis Harder aa7e7df19f simlib: Simplify recently changed $mux model 
The use of a procedural continuous assignment introduced in #3526 was
unintended and is completely unnecessary for the actual change of that
PR.

Consistent $mux undef handling
 2022-10-24 16:25:33 +02:00
Jannis Harder c77b7343d0 Consistent $mux undef handling 
* Change simlib's $mux cell to use the ternary operator as $_MUX_
  already does
* Stop opt_expr -keepdc from changing S=x to S=0
* Change const eval of $mux and $pmux to match the updated simlib
  (fixes sim)
* The sat behavior of $mux already matches the updated simlib

The verilog frontend uses $mux for the ternary operators and this
changes all interpreations of the $mux cell (that I found) to match the
verilog simulation behavior for the ternary operator. For 'if' and
'case' expressions the frontend may also use $mux but uses $eqx if the
verilog simulation behavior is requested with the '-ifx' option.

For $pmux there is a remaining mismatch between the sat behavior and the
simlib behavior. Resolving this requires more discussion, as the $pmux
cell does not directly correspond to a specific verilog construct.

Jannis Harder 0f96ae5990 Add smtmap.v describing the smt2 backend's behavior for undef bits 
Some builtin cells have an undefined (x) output even when all inputs are
defined. This is not natively supported by the formal backends which
will produce a fully defined value instead. This can lead to issues when
combining different backends in a formal flow. To work around these,
this adds a file containing verilog implementation of cells matching the
fully defined behavior implemented by the smt2 backend.

KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

Jannis Harder c0063288d6 Add the $anyinit cell and the formalff pass

use different backends simultaneously.

Sean Anderson 8c05f14b58 Order ports with default assignments first 
Although the current style is allowed by the standard, Icarus verilog
doesn't parse default assignments using an implicit net type:

	techlibs/ice40/cells_sim.v:305: syntax error
	techlibs/ice40/cells_sim.v:1: Errors in port declarations.

Fix this by making sure that ports with default assignments first on
their line.
