VVP SIMULATION ENGINE

standard VPI_MODULE_PATH for files named "name.vpi", and tries to
dynamic load them.
* :vpi_time_precision [+|-]<value>;
This header statement specifies the time precision of a single tick of
the simulation clock. This is mostly used for display (and VPI)
purposes, because the engine itself does not care about units. The
compiler scales time values ahead of time.
The value is the size of a simulation tick in seconds, and is
expressed as a power of 10. For example, +0 is 1 second, and -9 is 1
nano-second. If the record is left out, then the precision is taken to
be +0.
