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.)
