Counter

class pathsim.blocks.counter.Counter(start=0, threshold=0.0)

Bases: Block

Counts the number of detected bidirectional threshold crossings.

Uses zero-crossing events for the detection and sets the output accordingly.

Parameters:

• start (int) – counter start (initial condition)

• threshold (float) – threshold for zero crossing

E

internal event manager

Type:

ZeroCrossing

events

internal zero crossing event

Type:

list[ZeroCrossing]

input_port_labels = {'in': 0}

output_port_labels = {'out': 0}

update(t)

update system equation for fixed point loop, here just setting the outputs

Note

no direct passthrough, so the ‘update’ method is optimized for this case

Parameters:

t (float) – evaluation time

class pathsim.blocks.counter.CounterUp(start=0, threshold=0.0)

Bases: Counter

Counts the number of detected unidirectional (lo->hi) threshold crossings.

Note

This is a modification of ‘Counter’ which only counts unidirectional zero-crossings (low -> high)

Parameters:

• start (int) – counter start (initial condition)

• threshold (float) – threshold for zero crossing

E

internal event manager

Type:

ZeroCrossingUp

events

internal zero crossing event

Type:

list[ZeroCrossing]

class pathsim.blocks.counter.CounterDown(start=0, threshold=0.0)

Bases: Counter

Counts the number of detected unidirectional (hi->lo) threshold crossings.

Note

This is a modification of ‘Counter’ which only counts unidirectional zero-crossings (high -> low)

Parameters:

• start (int) – counter start (initial condition)

• threshold (float) – threshold for zero crossing

E

internal event manager

Type:

ZeroCrossingDown

events

internal zero crossing event

Type:

list[ZeroCrossing]
