uint32_t RealViewOsc::read ( ) const

References ClockDomain::_clockPeriod, DPRINTF, and SimClock::Float::s.

void RealViewOsc::serialize ( CheckpointOut & cp ) const

overridevirtual

Serialize an object.

Output an object's state into the current checkpoint section.

Parameters

cp	Checkpoint state

Implements Serializable.

Definition at line 257 of file rv_ctrl.cc.

References ClockDomain::_clockPeriod, and SERIALIZE_SCALAR.

void RealViewOsc::startup ( )

overridevirtual

startup() is the final initialization call before simulation.

All state is initialized (including unserialized state, if any, such as the curTick() value), so this is the appropriate place to schedule initial event(s) for objects that need them.

Reimplemented from SimObject.

void RealViewOsc::unserialize ( CheckpointIn & cp )

overridevirtual

Unserialize an object.

Read an object's state from the current checkpoint section.
