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

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 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.

Catherine b74d33d1b8 fmt: rename TIME to VLOG_TIME.
The behavior of these format specifiers is highly specific to Verilog
(`$time` and `$realtime` are only defined relative to `$timescale`)
and may not fit other languages well, if at all. If they choose to use
it, it is now clear what they are opting into.

This commit also simplifies the CXXRTL code generation for these format
specifiers.

Catherine a33acb7cd9 cxxrtl: refactor the formatter and use a closure.
This commit achieves three roughly equally important goals:
1. To bring the rendering code in kernel/fmt.cc and in cxxrtl.h as close
   together as possible, with an ideal of only having the bigint library
   as the difference between the render functions.
2. To make the treatment of `$time` and `$realtime` in CXXRTL closer to
   the Verilog semantics, at least in the formatting code.
3. To change the code generator so that all of the `$print`-to-`string`
   conversion code is contained inside of a closure.

There are two reasons to aim for goal (3):
a. Because output redirection through definition of a global ostream
   object is neither convenient nor useful for environments where
   the output is consumed by other code rather than being printed on
   a terminal.
b. Because it may be desirable to, in some cases, ignore the `$print`
   cells that are present in the netlist based on a runtime decision.
   This is doubly true for an upcoming `$check` cell implementing
   assertions, since failing a `$check` would by default cause a crash.
