Deprecations
|
|
============
|
|
|
|
The following deprecated items are scheduled for future removal:
|
|
|
|
C++14 compiler support
|
|
Verilator currently requires a C++20 or newer compiler for timing, and a
|
|
C++14 or newer compiler for both compiling Verilator and compiling
|
|
Verilated models with --no-timing.
|
|
|
|
Verilator will require C++20 or newer compilers for both compiling
|
|
Verilator and compiling all Verilated models no sooner than May 2025.
|
|
(Although this date has expired, this change is currently on hold until
|
|
the Ubuntu LTS versions of GCC and clang use C++20 by default, estimated
|
|
May 2028.)
|
|
|
|
`--structs-packed` option
|
|
The :vlopt:`--structs-packed` option was introduced when Verilator was
|
|
first implementing unpacked structs. That feature has been stable now
|
|
for multiple years, so :vlopt:`--structs-packed` should no longer be
|
|
used. Thus :vlopt:`--structs-packed` will change to a no-operation flag
|
|
and the related :option:`UNPACKED` warning will never be issued no
|
|
sooner than September 2026.
|
|
|
|
tcmalloc support
|
|
Verilator currently supports the default malloc, tcmalloc, or jemalloc.
|
|
As jemalloc has better performance, support for tcmalloc may be removed
|
|
no sooner than January 2027.
