George Rennie 8fb3f88842 tests: remove -seq 1 from sat with -tempinduct where possible 
* 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

Emil J. Tywoniak 01de9fb453 hashlib: extend unit test with subset collisions, shorten runtime 2025-08-20 00:08:23 +02:00
Robert O'Callahan 3a5742ffd2 Improve commutative hashing. 
The simple XOR `commutative_eat()` implementation produces a lot of collisions.
https://www.preprints.org/manuscript/201710.0192/v1/download is a useful reference on this topic.

Running the included `hashTest.cc` without the hashlib changes, I get 49,580,349 collisions.
The 49,995,000 (i,j) pairs (0 <= i < 10000, i < j < 10000) hash into only 414,651 unique hash values.
We get simple collisions like (0,1) colliding with (2,3).

With the hashlib changes, we get only 707,099 collisions and 49,287,901 unique hash values.
Much better! The `commutative_hash` implementation corresponds to `Sum(4)` in the paper
mentioned above.

This is @KrystalDelusion's suggestion in PR #5141 to verify
sensible implementation of all 4 possible full_case/parallel_case
combinations.

(Also including two similar tests to check the Verilog frontend
applies the correct attributes when given SystemVerilog
priority/unique case and if statements.)

Gary Wong 73e45d29d6 Add semantic test cases for SystemVerilog priority/unique/unique0 "if". 
The tests/verilog/*_if_enc.ys scripts instantiate simple encoder
modules, both with and without the SystemVerilog priority/unique/unique0
keywords, and check for consistency between the two for the subset
of inputs where the priority/unique/unique0 "if" result is
well-defined.

These tests vacuously succeed at the moment, since priority/unique
keywords are silently ignored and therefore the generated logic is
trivially identical.  But the test cases will be capable of detecting
certain types of unsound optimisation if priority/unique handling is
introduced later.

Gary Wong 9770ece187 Accept (and ignore) SystemVerilog unique/priority if. 
Add support to the "read_verilog -sv" parser to validate the
"unique", "unique0", and "priority" keywords in contexts where
they're legal according to 1800-2012 12.4.2.

This affects only the grammar accepted; the behaviour of conditionals
is not changed.  (But accepting this syntax will provide scope for
possible optimisations as future work.)

Three test cases ("unique_if", "unique_if_else", and
"unique_if_else_begin") verify that the keywords are accepted where
legal and rejected where illegal, as described in the final paragraph
of 12.4.2.

Mohamed Gaber 46ba89059a splitlarge: new pass to split wide arithmetic operators 
Adds a new pass, `splitlarge`, that recursively divides $add/$sub
cells into smaller cells until each cell's width doesn't exceed a
given max_width (128 by default.) An $add/$sub cell's width for
this purpose is defined as the higher of the widths of its two
inputs.

A test was written in Tcl for it, which tests this matrix:
- cell: $add/$sub
- b: unsigned, signed
- a: unsigned, signed

This is the first test for a Silimate pass in Tcl and thus
`run-test.sh` was modified to include it.

opt_expr: Fix #4590 
If all the (non-select) inputs of a `$_MUX{4,8,16}_` are undefined, replace it, just like we do for `$mux` and `$_MUX_`.
Add `tests/opt/opt_expr_mux_undef.ys` to verify this.

This doesn't do any const folding on the wide muxes, or shrinking to less wide muxes.  It only handles the case where all inputs are 'x and the mux can be completely removed.

Jannis Harder 0f13b55173 Liberty file caching with new `libcache` command 
This adds optional in-memory caching of parsed liberty files to speed up
flows that repeatedly parse the same liberty files. To avoid increasing
the memory overhead by default, the caching is disabled by default. The
caching can be controlled globally or on a per path basis using the new
`libcache` command, which also allows purging cached data.

simplify: Skip AST_PRIMITIVE in AST_CELLARRAY 
Otherwise the `AST_PRIMITIVE` simplifies to the corresponding function and is no longer caught by the check for `AST_PRIMITIVE`s, raising an assertion error instead of an input error.
Add bug4785.ys to tests/verilog to demonstrate.

select: Fix -none and -clear 
If the selection stack only has one element (which it normally does), then
`design->pop_selection()` automatically resets to the default full selection.
This is a problem for `select [-none | -clear]` which were trying to replace the
current selection, but because the pop added an extra element when the `execute`
returned, the extra selection (the one we actually wanted) gets popped too. So
instead, reassign `design->selection()` in the same way as if we called `select
[selection]`.

Also adds selection stack tests, and removes the accidentally-committed
`boxes_dummy.ys`.

tests: Fixes for boxes 
cxxrtl `test_unconnected_output` and simple_abc9 `abc9.v` both expect boxed modules in the outputs, so make sure they work as expected.
