Jannis Harder e1a59ba80b async2sync, clk2fflogic: Add support for $check and $print cells 2024-02-01 20:10:39 +01:00
Jannis Harder 6c4902313b chformal: Support $check cells and add chformal -lower 
This adds support for `$check` cells in chformal and adds a `-lower`
mode which converts `$check` cells into `$assert` etc. cells with a
`$print` cell to output the `$check` message.

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.

Philippe Sauter 68a9aa7c29 peepopt: handle offset too large in `shiftadd` 
If the offset is larger than the signal itself,
meaning the signal is completely shifted out,
it tried to extract a negative amount of bits from the old signal.

This RTL pattern is suspicious since it is a complicated way of
arriving at a constant value, so we warn the user.

Catherine fc5ff7a265 cxxrtl: always lazily format print messages. 
This is mostly useful for collecting coverage for the future `$check`
cell, where, depending on the flavor, formatting a message may not be
wanted even for a failed assertion.
