Jannis Harder 7203ba7bc1 Add bitwise `$bweqx` and `$bwmux` cells 
The new bitwise case equality (`$bweqx`) and bitwise mux (`$bwmux`)
cells enable compact encoding and decoding of 3-valued logic signals
using multiple 2-valued signals.

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 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 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.

Merge pull request #3526 from jix/mux-simlib-eval 
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.

In order to use those cores on sf2, it is required to discard the
initial value (to be carefully used).

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

Finds any log messages double indented (which help messages are)
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 
These can be used to protect undefined flip-flop initialization values
from optimizations that are not sound for formal verification and can
help mapping all solver-provided values in witness traces for flows that
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.

16bit*2K.

Supports mapping of these two kinds of BRAMs. 9Kbit BRAM in SDP mode and
32Kbit BRAM with 8bit width are not support yet.

abc9: fix SCC issues (#2694) 
* xilinx: add SCC test for DSP48E1

* xilinx: Gate DSP48E1 being a whitebox behind ALLOW_WHITEBOX_DSP48E1

Have a test that checks it works through ABC9 when enabled

* abc9 to break SCCs using $__ABC9_SCC_BREAKER module

* Add test

* abc9_ops: remove refs to (* abc9_keep *) on wires

* abc9_ops: do not bypass cells in an SCC

* Add myself to CODEOWNERS for abc9*

* Fix compile

* abc9_ops: run -prep_hier before scc

* Fix tests

* Remove bug reference pending fix

* abc9: fix for -prep_hier -dff

* xaiger: restore PI handling

* abc9_ops: -prep_xaiger sigmap

* abc9_ops: -mark_scc -> -break_scc

* abc9: eliminate hard-coded abc9.box from tests

Also tidy up

* Address review
