Detailed Description

Unit tests for the Verilator cosim backend.

These tests exercise the command-generation and CMake-template logic of the
Verilator class *without* requiring the compiled ``esiCppAccel`` C++
extension. We achieve this by inserting a ``MagicMock`` for the extension
module before the real package is imported.
