module to reduce the size of the interface class, to aid compile time at a
small performance loss.

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.
