Improve tracing performance. ( #2257 )
...
* Improve tracing performance.
Various tactics used to improve performance of both VCD and FST tracing:
- Both: Change tracing functions to templates to take variable widths as
template parameters. For VCD, subsequently specialize these to the
values used by Verilator. This avoids redundant instructions and hard
to predict branches.
- Both: Check for value changes via direct pointer access into the
previous signal value buffer. This eliminates a lot of simple pointer
arithmetic instructions form the tracing code.
- Both: Verilator provides clean input, no need to mask out used bits.
- VCD: pre-compute identifier codes and use memory copy instead of
re-computing them every time a code is emitted. This saves a lot of
instructions and hard to predict branches. The added D-cache misses
are cheaper than the removed branches/instructions.
- VCD: re-write the routines emitting the changes to be more efficient.
- FST: Use previous signal value buffer the same way as the VCD tracing
code, and only call the FST API when a change is detected.
Performance as measured on SweRV EH1, with the pre-canned CoreMark
benchmark running from DCCM/ICCM, clang 6.0.0, Intel i7-3770 @ 3.40GHz,
and IO to ramdisk:
+--------------+---------------+----------------------+
| VCD | FST | FST separate thread |
| (--trace) | (--trace-fst) | (--trace-fst-thread) |
------------+-----------------------------------------------------+
Before | 30.2 s | 121.1 s | 69.8 s |
============+==============+===============+======================+
After | 24.7 s | 45.7 s | 32.4 s |
------------+--------------+---------------+----------------------+
Speedup | 22 % | 256 % | 215 % |
------------+--------------+---------------+----------------------+
Rel. to VCD | 1 x | 1.85 x | 1.31 x |
------------+--------------+---------------+----------------------+
In addition, FST trace size for the above reduced by 48%.

Support vpiModule, bug1469.
...
Add very basic support for vpiModule. Basically it allows to traverse
the module tree to find a variable etc. It does not support more than
vpi_iterate and vpi_scan for vpiModule along basic operations like
vpi_get_str on vpiModule.
The support is added non-intrusively to non-VPI verilator runs. It
essentially:
- Tracks the creation of cell instances and keeps them alive until
the emit phase. They are there converted to scopes if modules.
- Emits empty (don't add anything during construction)
VerilatedScopes for all inlined modules, only for those inlined
modules that are on the hierarchical path to public variables.
- Adds VerilatedHierarchy as abstraction to structure of the
scopes. It is only created for VPI designs. It allows to traverse
the hierarchy from the top (NULL).
