HarnessCompilationFlags

This flag controls if VCS-specifc code is compiled.

Flags enabling various tracing mechanisms. Note: These flags do not cause tracing to occur, they simply support for these tracing mechanisms in the harness.

This flag controls whether Verilator coverage data writing support is compiled into the simulation harness.

Verilator support requires that we manually implement some SystemVerilog functions, such as run_simulation and simulation_main. These flags control the Verilator-specific code paths.

Verilator does not currently support delay (#delay) in DPI functions, so we omit the SystemVerilog definition of the run_simulation function and instead provide a C implementation.
