Specifies the module the comment appears in should not be inlined into any
modules that use this module. This is useful especially at the top level
module to reduce the size of the interface class, to aid compile time at a
small performance loss.

use these CC wrappers.
To reduce the compile time of classes that use a Verilated module (e.g. a
top CPP file) you may wish to add /*verilator no_inline_module*/ to your
top level module. This will decrease the amount of code in the model's
Verilated class, improving compile times of any instantiating top level C++
code, at a relatively small cost of execution performance.

Adding a new signal requires the symbol table to be recompiled. Verilator
