- Rename `--dump-treei` option to `--dumpi-tree`, which itself is now a
special case of `--dumpi-<tag>` where tag can be a magic word, or a
filename
- Control dumping via static `dump*()` functions, analogous to `debug()`
- Make dumping independent of the value of `debug()` (so dumping always
works even without the debug flag)
- Add separate `--dumpi-graph` for dumping V3Graphs, which is again a
special case of `--dumpi-<tag>`
- Alias `--dump-<tag>` to `--dumpi-<tag> 3` as before
The recent patch to defer substitutions on V3Gate crashes on circular
logic that has cycle length >= 3 with all inlineable signals (cycle
length 2 is detected correctly and is not inlined). Fix by stopping
recursion at the loop-back edge.
Fixes#3543
Fix compile error for queue method usage, if it is the
first statement in a block of code, and the return
value is not used. Example:
> if (foo)
> void'(bar.pop_front());
* Tests: Add a test to reproduce #3399
* Fix#3399. When reading an inout port in a module, it should refer the
original inout port, not the generated MODTEMP.
vcddiff is a bit broken, and sometimes 'vcddiff a b' fails while the
files are indeed equivalent. There is a chance however that 'vcddif b a'
will succeed in this case, so compare trace files both ways when
checking test results and claim success if vcddiff succeeds in at least
one direction.
* Tests: Add a test to reproduce #3509
* Tests: Compile without tautological-compare check because bit op tree optimization is disabled in the test.
* Internals: Dedup code. No functional change is intended.
* Fix#3509.
"2'b10 == (2'b11 & {1'b0, val[0]})" and "2'b10 != (2'b11 & {1'b0, val[0]})" were
wrongly optimized to "!val[0]" and "val[0]" respectively.
Now properly optimize them to 1'b0 and 1'b1.
* Commentary
* Commentary: Update Changes
These have been 'deprecated' for 2 years and are otherwise unused except
for using a temporary placeholder value, which I have inlined with the
default value.
Also remove the now VL_TIME_STR_CONVERT utility function (and
corresponding unit tests), which have no references in any project on
GitHub.
