Some values emitted to the trace files are constant (e.g.: actual
parameter values), and never change. Previously we used to trace these
in the 'full' dumps, which also included all other truly variable
signals. This patch introduces a new generated trace function 'const',
to complement the 'full' and 'chg' flavour, and 'const' now only
contains the constant signals, while 'full' and 'chg' contain only the
truly variable signals. The generate 'full' and 'chg' trace functions
now have exactly the same shape. Note that 'const' signals are still
traced using the 'full*' dump methods of the trace buffers, so there is
no need for a third flavour of those.
Again --prof-exec have bit-rotted a little with all the recent changes
to the structure of the generated code. This patch contains a few
improvements:
- Repalce the eval/evl_loop begin/end events with generic
section_push/section_pop events, that can be arbitrarily sprinkled
into the generate code (so long as they are matched correctly) to
measure various sections. The report then contains a nested profile
of the sections, and the VCD trace shows the section names.
- Better handling of exec graphs
- Clearer overall statistics
Still some remains of the --threads 0 mode. Remove unnecessary complexity
from V3EmitCModel. (Also don't pretend there is an MTask in single
threaded mode, when there really isn't.)
It's unlikely one value fits all use case, so making VL_LOCK_SPINS
configurable at model build time.
For testing, we reduce the value as we expect high contention.
This API is used if the user copies the process using `fork`
and similar OS-level mechanisms. The `at_clone` member function
ensures that all model-allocated resources are re-allocated, such
that the copied child process/model can simulate correctly.
A typical allocated resource is the thread pool, which every model
has its own pool.
* Ignore CLion project files and CMake outputs
* Supporting stripping file path that contains backslash
* Set /bigobj flag and increase stack size for windows platform
* Fix MSVC warnings
* Add VL_ASSERT_CAPABILITY; add assumeLocked and pretendUnlock to V3Mutex.
* Pass jobs as template-arguments and use std::packaged_task.
* Add and use V3ThreadPool::ScopedExclusiveAccess.
