Method Detail

subroutineCalled

public void subroutineCalled(int address,
                             int repetitions)

Specified by:

subroutineCalled in interface SequencerSimulation.SubroutineListener

subroutineReturned

public void subroutineReturned(int address)

Specified by:

subroutineReturned in interface SequencerSimulation.SubroutineListener

functionCalled

public void functionCalled(int function,
                           boolean infiniteLoop,
                           int repetitions)

Description copied from interface: SequencerSimulation.FunctionListener

Called whenever a new function is entered. Note that if repetitions==0 then the function is skipped (even if infiniteLoop is true) so in that case this method is not invoked.

Specified by:

functionCalled in interface SequencerSimulation.FunctionListener

Parameters:

function - The index of the function

infiniteLoop - true if the function will loop until stop/step

repetitions - The number of repetitions of this function

waitForState

public void waitForState(SequencerSimulation.State state,
                         Duration timeout)
                  throws InterruptedException,
                         TimeoutException

Throws:

InterruptedException

TimeoutException

stateChanged

public void stateChanged(SequencerSimulation.State oldState,
                         SequencerSimulation.State newState)

Description copied from interface: SequencerSimulation.StateListener

Called whenever the state of the sequencer changes

Specified by:

stateChanged in interface SequencerSimulation.StateListener

Parameters:

oldState - The state prior to the transitions

newState - The state after the transition

getSubroutineCounts

public Map<? extends Number,? extends Number> getSubroutineCounts()

getFunctionCounts

public Map<? extends Number,? extends Number> getFunctionCounts()

getSubroutineReturns

public Map<? extends Number,? extends Number> getSubroutineReturns()

transition

public void transition(int oldState,
                       int newState,
                       int nanos)

Description copied from interface: SequencerSimulation.WaveformListener

Called each time a function causes a change in the output waveform.

Specified by:

transition in interface SequencerSimulation.WaveformListener

Parameters:

oldState - The state of the outputs before the transition

newState - The status of the outputs after the transition

nanos - The number of nanoSeconds the outputs will remain in this state.

getAccumulatedNanos

public long getAccumulatedNanos()

getChecksum
