SystemC variables are fairly special (they can only be assigned to/from,

optimizations, but simplifies internals.

This adds support for arbitrary combinations of the above by
combining DfgSplicePacked and DfgSpliceArray vertices introduced in
#6176 . In particular, Sel(ArraySel(VarRef,_),_) enables a lot more code
to be represented in DFG.

Optimize DFG partial assignments ( #6176 )
...
This is mostly a refactoring, but also enables handling some more
UNOPTFLAT, when the variable is only partially assigned in the cycle.
Previously the way partial assignments to variables were handled were
through the DfgVerexVar types themselves, which kept track of all
drivers. This has been replaced by DfgVertexSplice (which always drives
a DfgVeretexVar), and all DfgVertexVar now only have a single source,
either a DfgVertexSplice, if partially assigned, or an arbitrary
DfgVertex when updated as a whole.

Safely support non-overlapping blocking/non-blocking assignments ( #6137 )
...
The manual for the BLKANDNBLK warning describes that it is safe to
disable that error if the updated ranges are non-overlapping. This
however was not true (see the added t_nba_mixed_update* tests).
In this patch we change V3Delayed to use a new ShadowVarMasked
scheme for variables that have mixed blocking and non-blocking
updates (or the FlagUnique scheme for unpacked variables), which
is in fact safe to use when the updated parts are non-overlapping.
Furthermore, mixed assignments are safe as far as scheduling is
concerned if either:
- They are to independent parts (bits/members/etc) (with this patch)
- Or if the blocking assignment is in clocked (or suspendable) logic.
The risk in scheduling is a race between the Post scheduled NBA
commit, and blocking assignments in combinational logic, which might
order incorrectly.
The second point highlights that we can handle stuff like this safely,
which is sometimes used in testbenches:
```systemverilog
always @(posedge clk) begin
if ($time == 0) a = 0;
end
always @(posedge clk) begin
if ($time > 0) a <= 2;
end
````
The only dangerous case is:
```systemverilog
always @(posedge clk) foo[idx] <= val;
assign foo[0] = bar;
```
Whit this patch, this will still resolve fine at run-time if 'idx' is
never zero, but might resolve incorrectly if 'idx' is zero.
With the above in mind, the BLKANDNBLK warning is now only issued if:
- We can't prove that the assignments are to non-overlapping bits
- And the blocking assignment is in combinational logic
These are the cases that genuinely require user attention to resolve.
With this patch, there are no more BLKANDNBLK warnings in the RTLMeter
designs.

These passes blow up the Ast size on some designs, so delaying running V3Const
until after the whole pass can notably increase peak memory usage. In this
patch we apply V3Const per CFunc within these passes, which saves on memory.
Added -fno-const-eager to disable the intra-pass V3Const application, for
debugging.

Fix DFG binToOneHot table index missing driver ( #6100 )
2025-06-17 15:53:47 +01:00
277611bcdd
Add DFG binToOneHot pass to generate one-hot decoders ( #6096 )
...
Somewhat commonly, there is code out there that compares an expression (or
variable) against many different constants, e.g. a one-hot decoder:
```systemverilog
assign oneHot = {x == 3, x == 2, x == 1, x == 0};
```
If the width of the expression is sufficiently large, this can blow up
a GCC pass and take an egregious amount of memory and time to compile.
Adding a new DFG pass that will generate a cheap one-hot decoder:
to compute:
```systemverilog
wire [$bits(x)-1:0] idx = <the expression being compared many times>
reg tab [1<<$bits(x)] = '{default: 0};
reg [$bits(x)-1:0] pre = '0;
always_comb begin
tab[pre] = 0;
tab[idx] = 1;
pre = idx ; // This assignment marked to avoid a false UNOPFTLAT
end
```
We then replace the comparisons `x == CONST` with `tab[CONST]`.
This is generally performance neutral, but avoids the compile time and memory
blowup with GCC (128GB+ -> 1GB in one example).
We do not apply this if the comparisons seem to be part of a `COMPARE ?
val : COND` conditional tree, which the C++ compilers can turn into jump
tables.
This enables all XiangShan configurations from RTLMeter to now build with GCC,
so in this patch we enabled those in the nightly runs.

Preserve C++ widths in V3Expand ( #5975 )
...
During V3Expand, some w32/1 (width == 32, widthMin == 1), nodes (e.g.:
RedOr) are replaced with w1 nodes (width == widthMin == 1) (e.g.: Neq).
However, V3Expand runs after V3Clean, when we are in C++ width world,
so we need to preserve the width/widthMin distinction, otherwise a later
constant folding can eliminate e.g. a necessary AstAnd used clear an
intermediate result (isAllOnes is true for a Const 1 with w1, but false
for a Const 1 with w32/1).
Attempting to fix by preserving all width/widthMin during a replacement
in V3Expand.
DFG itself is fine, but the transformed code hits the above.
