Jannis Harder 0db76c6ec4 tests/sva: Skip sva tests that use SBY until SBY is compatible again 
This commit is part of a PR that requires corresponding changes in SBY.
To prevent CI failures, detect whether those changes already landed and
skip the SBY using tests until then.

Austin Rovinski 689feed012 dfflibmap: Add a -dont_use flag to ignore cells 
This is an alternative to setting the dont_use property in lib. This brings
dfflibmap in parity with the abc pass for dont_use.

Amelia Cuss bf4a46ccb3 proc_rom: don't assert on big actionless switch. 
See the test case.  PROC_ROM will consider this for evaluation, even
though -- without any actions -- lhs is empty (but still "uniform").
A zero-width memory is constructed, which later fails check with:

ERROR: Assert `width != 0' failed in kernel/mem.cc:518.

Ensure we don't proceed if there's nothing to encode.

Jannis Harder bbdfcfdf30 clk2fflogic: Fix handling of $check cells 
Fixes a bug in the handling of the recently introduced $check cells.
Both $check and $print cells in clk2fflogic are handled by the same code
and the existing tests for that were only using $print cells. This
missed a bug where the additional A signal of $check cells that is not
present on $print cells was dropped due to a typo, rendering $check
cells non-functional.

Also updates the tests to explicitly cover both cell types such that
they would have detected the now fixed bug.

Dag Lem a32d9b6c45 Fix test of memory vs. memory converted to registers 
The purpose of memtest02 in tests/simple/memory.v is to	test bit
select on both memory (mem1) and memory converted to registers (mem2).

After 7cfae2c52, mem1 was automatically converted to registers,
and the test no longer worked as intended. This is fixed by
adding (* nomem2reg *) to mem1.

Jannis Harder 0470cbb00d hierarchy: Without a known top module, derive all deferred modules 
This fixes hierarchy when used with cell libraries that were loaded with
-defer and also makes more of the hierarchy visible to the auto-top
heuristic.

Jannis Harder e1a59ba80b async2sync, clk2fflogic: Add support for $check and $print cells 2024-02-01 20:10:39 +01:00
Jannis Harder 331ac5285f tests: Run async2sync before sat and/or sim to handle $check cells 
Right now neither `sat` nor `sim` have support for the `$check` cell.
For formal verification it is a good idea to always run either
async2sync or clk2fflogic which will (in a future commit) lower `$check`
to `$assert`, etc.

While `sim` should eventually support `$check` directly, using
`async2sync` is ok for the current tests that use `sim`, so this commit
also runs `async2sync` before running sim on designs containing
assertions.

Jannis Harder 2baa578d94 Remove too fragile smtlib2_module test 
This compares the write_smt2 output pretty much verbatim, which contains
auto generated private names and fixes an arbitrary ordering. The tested
functionality is also covered by SBY tests which actually interpret the
write_smt2 output using an SMT solver and thus are much more robust, so
we can safely remove this test.
