Purpose

Detect edges of pulse signal in given direction

Library

Control / Logical

Description

pict

The output of the edge detection block changes to 1 if an edge is detected on the input signal. It returns to 0 in the following simulation step.

The block allows you to detect the following edges:

rising
The output is set to 1 when the input changes from 0 to a positive value.
falling
The output is set to 1 when the input changes from a positive value to 0.
either
The output is set to 1 when the input changes from 0 to a positive value or vice versa.

Parameter

Edge direction
The direction of the edges to detect, as described above.

Probe Signals

Input
The input signal.
