V3Randomize: Fix dist operator inside ConstraintIf blocks ( #7221 ) ( #7224 )
...
The lowerDistConstraints() function was not recursing into ConstraintIf
nodes, causing dist operators inside if-else blocks to remain unlowered
and trigger an internal error when ConstraintExprVisitor encountered them.
Fix by adding recursive handling of ConstraintIf nodes in lowerDistConstraints:
- Check for AstConstraintIf nodes before AstConstraintExpr
- Recursively process thensp() and elsesp() branches
- This ensures all dist operators are lowered regardless of nesting
Test case: t_randomize_dist_conditional.v demonstrates conditional dist:
constraint c {
if (randd) {
x dist { 8'd0 := 1, 8'd255 := 3 }; // 25% / 75%
} else {
x dist { 8'd0 := 3, 8'd255 := 1 }; // 75% / 25%
}
}

Optimize conditional merging across some impure statements ( #7159 )
...
- Allow reordering pure statements with DPI import calls iff no public
variables (including those read via a DPI export) are involved. This
ensures the DPI import can't observe the reordering
- Allow reordering of pure statements with AstDisplay and AstStop. This
requires an assumption that AstDisplay and AstStop will not read or
write model state other than via a VarRef explicitly present int the
Ast.
Overall this allows eliminating a lot of conditionals around assertions,
which were previously not possible.

Add V3LiftExpr pass to lower impure expressions and calls ( #7141 )
...
Introduce new pass that converts impure expressions, or those with
function and method calls into simple assignment statements. Please see
the blurb at the top of the file why this is useful and how it works.
In particular currently it enables more Dfg optimization as functions
will be inlined without AstExprStmt.
Ideally we should enforce this lowering is applied to every procedural
statement (there are still a handful of exceptions). With that, long
term with this pass + #6820 , there should be no need to ever use an
AstExprStmt past this new lowering pass, which should enable more easier
optimization down the line.
Also ideally this should be run earlier. Currently it's after V3Tristate
as that calls pinReconnectSimple so we don't have to touch Cell ports.
Currently disabled when code coverage is enabled due to #7119 .

Support #0 delays with IEEE-1800 compliant semantics ( #7079 )
...
This patch adds IEEE-1800 compliant scheduling support for the Inactive
scheduling region used for #0 delays.
Implementing this requires that **all** IEEE-1800 active region events
are placed in the internal 'act' section. This has simulation
performance implications. It prevents some optimizations (e.g.
V3LifePost), which reduces single threaded performance. It also reduces
the available work and parallelism in the internal 'nba' section, which
reduced the effectiveness of multi-threading severely.
Performance impact on RTLMeter when using scheduling adjusted to support
proper #0 delays is ~10-20% slowdown in single-threaded mode, and ~100%
(2x slower) with --threads 4.
To avoid paying this performance penalty unconditionally, the scheduling
is only adjusted if either:
1. The input contains a statically known #0 delay
2. The input contains a variable #x delay unknown at compile time
If no #0 is present, but #x variable delays are, a ZERODLY warning is
issued advising the use of '--no-sched-zero-delay' which is a promise
by the user that none of the variable delays will evaluate to a zero
delay at run-time. This warning is turned off if '--sched-zero-delay'
is explicitly given. This is similar to the '--timing' option.
If '--no-sched-zero-delay' was used at compile time, then executing
a zero delay will fail at runtime.
A ZERODLY warning is also issued if a static #0 if found, but the user
specified '--no-sched-zero-delay'. In this case the scheduling is not
adjusted to support #0 , so executing it will fail at runtime. Presumably
the user knows it won't be executed.
The intended behaviour with all this is the following:
No #0 , no #var in the design (#constant is OK)
-> Same as current behaviour, scheduling not adjusted,
same code generated as before
Has static #0 and '--no-sched-zero-delay' is NOT given:
-> No warnings, scheduling adjusted so it just works, runs slow
Has static #0 and '--no-sched-zero-delay' is given:
-> ZERODLY on the #0 , scheduling not adjusted, fails at runtime if hit
No static #0 , but has #var and no option is given:
-> ZERODLY on the #var advising use of '--no-sched-zero-delay' or
'--sched-zero-delay' (similar to '--timing'), scheduling adjusted
assuming it can be a zero delay and it just works
No static #0 , but has #var and '--no-sched-zero-delay' is given:
-> No warning, scheduling not adjusted, fails at runtime if zero delay
No static #0 , but has #var and '--sched-zero-delay' is given:
-> No warning, scheduling adjusted so it just works

Internals: Make AstCAwait an AstNodeStmt ( #6280 ) ( #7078 )
...
AstCAwait is only ever uses in statement position, so model it as a
statement. We should never ever have a coroutine that returns a value.
There is no need for it in SV, nor should we rely on it for internals.
Also reworks the fix for V3Life incorrectly constant propagating the
beforeTrig functions (#7072 ). The property that upsets V3Life is that
a function:
1. Is called from multiple static call sites (multiple AstCCall)
2. Reads model state directly (AstVarRef to non-locals/arguments)
Such function can only be created internally after scheduling (V3Task
throws an unsupported error on a non-inlined function that reads model
state), so added a flag to AstCFunc to mark the dangerous ones for
V3Life.

Fix C++ types of non-inlined module ports ( #7002 )
...
We use special C++ types for ports, e.g. SystemC types in --sc mode, and native C arrays for unpacked arrays in --cc mode. These types are not substitutable for internal types, e.g. VlUnpacked, however all the runtime primitives expect internal types.
I think the intention was to use these special IO types only for top level ports, but the current implementation also uses them for the ports of all non-inlined modules. This means the output C++ will not compile if such a port is passed to a runtime primitive (e.g. array 'sort' as in the new test) or DPI import.
Changed to use the special IO types only on the top level ports.
Note these are likely still broken if attempting to invoke on a top level port (we might be saved by wrapTop, but later optimizations might eliminate the intermediary)

straight assignments with a ConstPool entry on the RHS. This allows the

Optimize more wide operation temporaries with substitution ( #6972 )

A temporary introduced by V3Premit could not be eliminated in V3Subst if
it was involved in an expression that did a write back to a
non-temporary. To enables removing these, we need to track all variables
in V3Subst, not just the ones we would consider for elimination. Note
the new implementation is marginally faster than the old one even though
it does more work. It can eliminate ~5% more of wide temporaries on some
designs. Algorithm is largely the same.

Improve combinational cycle fixup in Dfg ( #6744 ) ( #6746 )
...
Now that we have an efficient algorithm to analyse which bits in a
combinational cycle are not dependent on the cycle, can simplify the
cycle fixup algorithms. Remove FixUpSelDrivers: this was a heuristic
to save on the expensive independent bits analysis, but itself can
cause a performance problem on certain inputs that result in a large
number of attempted fixups. Doing this simplifies the driver tracing
algorithm, and because we now only attempt to trace drivers that are
known to be independent of the cycles, it should always succeed...
Unless of course there is a mismatch between the independent bit
analysis ant the driver tracing algorithm. In such case (when we managed
to prove independence, but then fail to trace a driver), we will crash,
which is still easier to sv-bugpoint than a performance bug.
