* Require C++20 for the new --timing features. Upgrading to a C++20 or

|
|
|
|
newer compiler is strongly recommended.
|
|
|

|
* Support the Active and NBA scheduling regions as defined by the
|
2022-05-15 15:03:32 +00:00
|
|
|
SystemVerilog standard (IEEE 1800-2017 chapter 4). This means all generated
|
|
|
|
|
clocks are now simulated correctly (#3278, #3384). [Geza Lore, Shunyao CAD]

Timing support (#3363)
Adds timing support to Verilator. It makes it possible to use delays,
event controls within processes (not just at the start), wait
statements, and forks.
Building a design with those constructs requires a compiler that
supports C++20 coroutines (GCC 10, Clang 5).
The basic idea is to have processes and tasks with delays/event controls
implemented as C++20 coroutines. This allows us to suspend and resume
them at any time.
There are five main runtime classes responsible for managing suspended
coroutines:
* `VlCoroutineHandle`, a wrapper over C++20's `std::coroutine_handle`
with move semantics and automatic cleanup.
* `VlDelayScheduler`, for coroutines suspended by delays. It resumes
them at a proper simulation time.
* `VlTriggerScheduler`, for coroutines suspended by event controls. It
resumes them if its corresponding trigger was set.
* `VlForkSync`, used for syncing `fork..join` and `fork..join_any`
blocks.
* `VlCoroutine`, the return type of all verilated coroutines. It allows
for suspending a stack of coroutines (normally, C++ coroutines are
stackless).
There is a new visitor in `V3Timing.cpp` which:
* scales delays according to the timescale,
* simplifies intra-assignment timing controls and net delays into
regular timing controls and assignments,
* simplifies wait statements into loops with event controls,
* marks processes and tasks with timing controls in them as
suspendable,
* creates delay, trigger scheduler, and fork sync variables,
* transforms timing controls and fork joins into C++ awaits
There are new functions in `V3SchedTiming.cpp` (used by `V3Sched.cpp`)
that integrate static scheduling with timing. This involves providing
external domains for variables, so that the necessary combinational
logic gets triggered after coroutine resumption, as well as statements
that need to be injected into the design eval function to perform this
resumption at the correct time.
There is also a function that transforms forked processes into separate
functions.
See the comments in `verilated_timing.h`, `verilated_timing.cpp`,
`V3Timing.cpp`, and `V3SchedTiming.cpp`, as well as the internals
documentation for more details.

statements) and forks. [Krzysztof Bieganski, Antmicro Ltd]

This may require adding --timing or --no-timing. See docs for details.
|
2022-10-11 09:06:05 +00:00

|
|
|
|
significant performance improvements on some designs. [Geza Lore, Shunyao CAD]
|
2022-09-28 23:02:07 +00:00

|
2022-10-21 23:10:06 +00:00
|
|
|
For designs where C++ was only used to make a simple no-I/O testbench, we
|
2022-10-16 15:10:41 +00:00
|
|
|
recommend abandoning that C++, and instead letting Verilator build it
|
|
|
|
|
with --binary (or --main).

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.

* The generated model class instantiated by the user is now an interface

To support --output-split, the makefiles now split VM_CLASSES

* Verilator now uses 64 bit math where appropriate.
|
|
|
|
|
Inputs and outputs of 33-64 bits wide to the C++ Verilated model must
|
|
|
|
|
now be uint64_t's; SystemC has not changed, they will remain sc_bv's.
|
|
|
|
|
This increases performance by ~ 9% on x86 machines, varying with how
|
|
|
|
|
frequently 33-64 bit signals occur. Signals 9-16 bits wide are now
|
|
|
|
|
stored as 16 bit shorts instead of longs, this aids cache packing.

* Version 3.2XX includes an all new back-end.
|
2021-03-14 18:11:57 +00:00
|
|
|
This includes automatic inlining, flattening of signals between
|
|
|
|
|
hierarchy, and complete ordering of statements. This results in
|
|
|
|
|
60-300% execution speedups, though less pretty C++ output. Even
|
|
|
|
|
better results are possible using GCC 3.2.2 (part of Redhat 9.1), as
|
|
|
|
|
GCC has fixed some optimization problems which Verilator exposes.

If you are using `systemc_ctor, beware pointers to submodules are now
|
|
|
|
|
initialized after the constructor is called for a module, to avoid
|
|
|
|
|
segfaults, move statements that reference subcells into initial
|
|
|
|
|
statements.
|
|
|
|
|
* C++ Constructor that creates a verilog module may take a char* name.
|
|

|
This name will be used to prefix any $display %m arguments, so users may
|
|
|
|
|
distinguish between multiple Verilated modules in a single executable.

For example $c("foo","bar(",32+1,");") will insert "foobar(33);"
|
|
|
|
|
This makes it easier to pass the values of signals.
|
|
|
|
|
* Several changes to support future versions that may have
|
|
|
|
|
signal-eliminating optimizations. Users should try to use these switch
|
|
|
|
|
on designs, they will become the default in later versions.
|
|
|
|
|
* Add --private switch and /*verilator public*/ metacomment.
|
|
|
|
|
This renames all signals so that compile errors will result if any
|
|
|
|
|
signals referenced by C++ code are missing a /*verilator public*/
|
|
|
|
|
metacomment.
|
|
|
|
|
* With --l2name, the second level cell C++ cell is now named "v".
|
|
|
|
|
Previously it was named based on the name of the verilog code. This
|
|
|
|
|
means to get to signals, scope to "{topcell} ->v ->{mysignal}" instead
|
|
|
|
|
of "{topcell} ->{verilogmod}. {mysignal}". This allows different
|
|
|
|
|
modules to be substituted for the cell without requiring source
|
|
|
|
|
changes.

* New test_sp directory for System-Perl (SystemC) top level instantiation

|
|
|
of the Verilated code, lower modules are still C++ code. (Experimental).

* Input ports are now loaded by pointer reference into the sub-cell.
|
|
|
|
|
This is faster on I-386 machines, as the stack must be used when there are
|
|
|
|
|
a large number of parameters. Also, this simplifies debugging as the value
|
|
|
|
|
of input ports exists for tracing.
|
|
|
|
|
* Many code cleanups towards standard C++ style conventions.
