Public Class methods

Public Instance methods

advance_time(aNumSteps = 1)

Advances the simulation by the given number of steps.

simulate()

Simulates the design under test according to RubyVpi.init_bench.

simulation_time()

Returns the current simulation time as an integer.

vpi_register_cb(aData {|Vpi::S_cb_data| ...}

This is a Ruby version of the vpi_register_cb C function. It is identical to the C function, except for the following differences:

  • This method accepts a block (callback handler) which is executed whenever the callback occurs.
  • This method overwrites the cb_rtn and user_data fields of the given S_cb_data object.
