Reduce .rodata footprint of trace initialization ( #3250 )
...
Trace initialization (tracep->decl* functions) used to explicitly pass
the complete hierarchical names of signals as string constants. This
contains a lot of redundancy (path prefixes), does not scale well with
large designs and resulted in .rodata sections (the string constants) in
ELF executables being extremely large.
This patch changes the API of trace initialization that allows pushing
and popping name prefixes as we walk the hierarchy tree, which are
prepended to declared signal names at run-time during trace
initialization. This in turn allows us to emit repeat path/name
components only once, effectively removing all duplicate path prefixes.
On SweRV EH1 this reduces the .rodata section in a --trace build by 94%.
Additionally, trace declarations are now emitted in lexical order by
hierarchical signal names, and the top level trace initialization
function respects --output-split-ctrace.

Make 'bit', 'logic' and 'time' types unsigned by default

IEEE 1800-2017 6.11.3 says these types are unsigned. Until now these
types were treated as not having a signedness (NOSIGN), and nodes having
these types were later resolved by V3Width to be unsigned. This is a bit
problematic when creating nodes of these types after V3Width. Treating
these types as unsigned from the get go is fine, and actually improves
generated code slightly.

non-local variable, we create a global __Vdpi_export_trigger flag, that
is set in the body of the DPI export, and make all variables set in any
DPI exported functions dependent on this flag (this ensures correct
ordering and change detection on state set in DPI exports when needed).
The DPI export trigger flag is cleared at the end of eval, which ensured
calls to DPI exports outside of eval are detected. Additionally the
ordering is modifies to assume that any call to a 'context' DPI import
might call DPI exports by adding an edge to the ordering graph from the
logic vertex containing the call to the DPI import to the DPI export
trigger variable vertex (note the standard does not allow calls to DPI
exports from DPI imports that were not imported with 'context', so we
do not enforce ordering on those).

Add V3VariableOrder pass
...
A separate V3VariableOrder pass is now used to order module variables
before Emit. All variables are now ordered together, without
consideration for whether they are ports, signals form the design, or
additional internal variables added by Verilator (which used to be
ordered and emitted as separate groups in Emit). For single threaded
models, this is performance neutral. For multi-threaded models, the
MTask affinity based sorting was slightly modified, so variables with no
MTask affinity are emitted last, otherwise the MTask affinity sets are
sorted using the TSP sorter as before, but again, ports, signals, and
internal variables are not differentiated. This yields a 2%+ speedup for
the multithreaded model on OpenTitan.

MTaskState does not concern itself with sandbagging, and thus solely contains information related to the finalized schedule, i.e., completion time, thread ID and next MTask on thread.
* Add .dot graph visualization of ThreadSchedule
Follow-up to #2779 .
This commit adds the creation of .dot files - used by GraphViz - to visualize how mtasks are statically scheduled across the set of specified threads.
We visualize each thread as a row, with nodes of a row being the mtasks scheduled for the given thread. The width of the mtask nodes are proportional to their cost. MTask dependencies are shown using an edge between the source and sink mtasks.

Tests: Add simulator benchmarking data option for regression tests ( #3054 )
...
This commit adds the '--simbenchmark' option to the regression test compile command.
The option is not intended as a fully-fledged benchmarking infrastructure, but rather a
utility for easily generating cycle- and execution time information when executing a verilated test.
As an example use case, the included test file shows how optimization level is varied across
three different builds+simulations, with the statistics for each run output to the same file in
the output directory.
Future work:
- 'sim_time' in the generated top-level main file should be a parameter.
- Given the above, the test execution script from verilog-sim-benchmark can be integrated
to generate better estimates of cycles/second through varying 'sim_time' over multiple executions.

Introduce model interface class, make $root part or Syms ( #3036 )
...
This patch implements #3032 . Verilator creates a module representing the
SystemVerilog $root scope (V3LinkLevel::wrapTop). Until now, this was
called the "TOP" module, which also acted as the user instantiated model
class. Syms used to hold a pointer to this root module, but hold
instances of any submodule. This patch renames this root scope module
from "TOP" to "$root", and introduces a separate model class which is
now an interface class. As the root module is no longer the user
interface class, it can now be made an instance of Syms, just like any
other submodule. This allows absolute references into the root module to
avoid an additional pointer indirection resulting in a potential speedup
(about 1.5% on OpenTitan). The model class now also contains all non
design specific generated code (e.g.: eval loops, trace config, etc),
which additionally simplifies Verilator internals.
Please see the updated documentation for the model interface changes.

Construct AstExecGraph implementation outside of V3EmitC. ( #3022 )
...
The goal of this patch is to move functionality related to constructing
the thread entry points and then invoking them out of V3EmitC (and into
V3Partition). The long term goal being enabling V3EmitC to emit
functions partitioned based on header dependencies. V3EmitC having to
deal with only AstCFunc instances and no other magic will facilitate
this.
In this patch:
- We construct AstCFuncs for each thread entry point in
V3Partition::finalize and move AstMTaskBody nodes under these functions.
- Add the invocation of the threads as text statements within the
AstExecGraph, so they are still invoked where the exec graph is located.
(the entry point functions are still referenced via AstCCall or
AstAddOrCFunc, so lazy declarations of referenced functions are created
automatically).
- Explicitly handle MTask state variables (VlMTaskVertex in
verilated_threads.h) within Verilator, so no need to text bash a lot of
these any more (some text refs still remain but they are all created
next to each other within V3Partition.cpp).
The effect of all this on the emitted code should be nothing but some
identifier/ordering changes. No functional change intended.

Implement a distinct constant pool ( #3013 )

What previously used to be per module static constants created in

pool are global variables which are declared lazily when used (similar to
loose methods).

Emit model implementation as loose methods. ( #3006 )

This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.

Allow overlaps in priority case statements ( #2864 )
...
This will still warn if a case item is completely covered by previous
items, but will no longer complain about overlaps like this:
priority casez (foo_i)
2'b ?1: bar_o = 3'd0;
2'b 1?: bar_o = 3'd1;
Before, there was a warning for the second statement because the first
two patterns match 2'b11.

Travis: Use workspaces and per job persistent ccache ( #2399 )
...
Change the Travis builds to use workspaces and persistent ccache
We proceed in 2 stages (as before, but using workspaces for
persistence):
1. In the 'build' stage, we clone the repo, build it and
save the whole checkout ($TRAVIS_BUILD_DIR) as a workspace
2. In the 'test' stage, rather than cloning the repo, multiple jobs
pull down the same workspace we built to run the tests from
This enables:
- Reuse of the build in multiple test jobs (this is what we used the Travis
cache for before)
- Each job having a separate persistent Travis cache, which now only
contains the ccache. This means all jobs, including 'build' and 'test'
jobs can make maximum use of ccache across runs. This drastically cuts
down build times when the ccache hits, which is very often the case for
'test' jobs. Also, the separate caches only store the objects build by
the particular job that owns the cache, so we can keep the per job
ccache small.
If the commit message contains '[travis ccache clear]', the ccache will
be cleared at the beginning of the build. This can be used to test build
complete within the 50 minute timeout imposed by Travis, even without a
persistent ccache.

Generate file with waivers ( #2354 )

This adds the flag --generate-waivefile <filename>. This will generate

warnings emitted during this particular run.
This feature can be used to start with using Verilator as linter and
systematically capture all known lint warning for further
elimination. It hopefully helps people turning of -Wno-fatal or
-Wno-lint and gradually improve their code base.

Rework serial/parallel build mode
...
Instead of __ALLfast.cpp and __ALLslow.cpp, we now create only a single
__ALL.cpp and compile it with OPT_FAST, this speeds up small builds
where the C compiler does not dominate. A separate patch will follow
turning VM_PARALLEL_BUILDS on by default at a certain size.
Given this change to the build there is now no point in emitting both
fast and slow routines into the same .cpp file when --output-split is
not set as they will be just included in the same __ALL.cpp file. To
keep things simpler and the output easier to comprehend, V3EmitC has
also been changed to always emit the fast and slow files separately.
Also change verilated.mk to apply OPT_SLOW to all slow files, not just
ones called *__Slow.cpp. This change in particular ensures __Syms.cpp
is build as slow.

Optimize fine grained trace activity flags ( #2336 )
...
Firstly, we always use a byte array for fine grained activity flags
instead of a bit vector (we used to use a byte array only if we had
parallel mtasks). The byte vector can be set more cheaply in eval,
closing about 1/3 of the gap in performance between compiling with
or without --trace on SweRV EH1. The speed of tracing itself is not
measurably different.
Secondly, we prune the activity tracking such that if a set of activity
flag combinations only guard a small number of signals, we will turn
those signals into awayls traced signals. This avoids code which
sometimes tests dozens of activity flags just to subsequently check one
signal and dump it if it's value changed. We can just check the signal
state straight instead, and not bother with the flags. This removes
about 30% of activity flags in SweRV EH1, and makes both single threaded
VCD and FST tracing 8-9% faster.

Use SIMD intrinsics to render VCD traces ( #2289 )
...
Use SIMD intrinsics to render VCD traces.
I have measured 10-40% single threaded performance increase with VCD
tracing on SweRV EH1 and lowRISC Ibex using SSE2 intrinsics to render
the trace. Also helps a tiny bit with FST, but now almost all of the FST
overhead is in the FST library.
I have reworked the tracing routines to use more precisely sized
arguments. The nice thing about this is that the performance without the
intrinsics is pretty much the same as it was before, as we do at most 2x
as much work as necessary, but in exchange there are no data dependent
branches at all.

Initial implementation of generic multithreaded tracing ( #2269 )
...
The --trace-threads option can now be used to perform tracing on a
thread separate from the main thread when using VCD tracing (with
--trace-threads 1). For FST tracing --trace-threads can be 1 or 2, and
--trace-fst --trace-threads 1 is the same a what --trace-fst-threads
used to be (which is now deprecated).
Performance numbers on SweRV EH1 CoreMark, clang 6.0.0, Intel i7-3770 @
3.40GHz, IO to ramdisk, with numactl set to schedule threads on different
physical cores. Relative speedup:
--trace -> --trace --trace-threads 1 +22%
--trace-fst -> --trace-fst --trace-threads 1 +38% (as --trace-fst-thread)
--trace-fst -> --trace-fst --trace-threads 2 +93%
Speed relative to --trace with no threaded tracing:
--trace 1.00 x
--trace --trace-threads 1 0.82 x
--trace-fst 1.79 x
--trace-fst --trace-threads 1 1.23 x
--trace-fst --trace-threads 2 0.87 x
This means FST tracing with 2 extra threads is now faster than single
threaded VCD tracing, and is on par with threaded VCD tracing. You do
pay for it in total compute though as --trace-fst --trace-threads 2 uses
about 240% CPU vs 150% for --trace-fst --trace-threads 1, and 155% for
--trace --trace threads 1. Still for interactive use it should be
helpful with large designs.

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%.

Allow assert disable ( #2168 )
...
* Add +verilator+noassert flag
This allows to disable the assert check per simulation argument.
* Add AssertOn check for assert
Insert the check AssertOn to allow disabling of asserts.
Asserts can be disabled by not using the `--assert` flag or by calling
`AssertOn(false)`, or passing the "+verilator+noassert" runtime flag.
Add tests for this behavior.
Bad tests check that the assert still causes a stop.
Non bad tests check that asserts are properly disabled and cause no stop
of the simulation.
Fixes #2162 .

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).
