Zachary Snow 71e7e09092 verilog: Support module-scoped task/function calls 
This is primarily intended to enable the standard-permitted use of
module-scoped identifiers to refer to tasks and non-constant functions.
As a side-effect, this also adds support for the non-standard use of
module-scoped identifiers referring to constant functions, a feature
that is supported in some other tools, including Iverilog.

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 #3523 from lparkes/basename 
Replace GNU specific invocation of basename(1) with the equivalent POSIX one
 2022-10-24 12:13:09 +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.

Jannis Harder 96029400cb smtbmc: Do not assume skipped assertions when loading a witness trace 
This is not valid when the prefix of a trace already violates
assertions. This can happen when the trace generating solver doesn't
look for a minimal length counterexample.

Emil J 8859d801c8
Temporal induction counterexample loop detection (#3504) 
I have added an optional flag to smtbmc that causes failed temporal induction counterexample traces to be checked for duplicate states and reported to the user, since loops in the counterexample mean that increasing the induction depth won't help prove a design's safety properties.

Lloyd Parkes 7dcc9c664e And another place we need to lseek() after dup(). 2022-10-16 12:50:49 +13:00
Lloyd Parkes 635aa2a3fc Forcibly set the current seek location of gz files that we are accessing 
via dup(fileno());gzdopen() because stdio might have buffered data from
the underlying file meaning that the underlying seek position isn't what
we think it is.

Jannis Harder 4d334fd3e3 smt2/smtbmc: Fix FF witness data for fine grained or multi chunk FFs 
The witness metadata was missing fine grained FFs completely and for
coarse grained FFs where the output connection has multiple chunks it
lacked the offset of the chunk within the SMT expression. This fixes
both, the later by adding an "smtoffset" field to the metadata.
