Analyze Waveform Data
The Wave Inspector includes the following search capabilities:
Search Description
Edge
Searches for edges (rising or falling) with a user-specified threshold level.
Pulse Width
Searches for positive or negative pulse widths that are > , <, =, or ≠ a user specified pulse width.
Runt
Searches for positive or negative pulses th at cross one amplitude threshold but fail to cross a
second threshold before crossing the first again. Search for all runt pulses or only those with a
duration >, <, =, or ≠ a user specifi ed time.
Logic
Search for a logic pattern (AND, OR, NAND, or NOR) across multiple waveforms with each input
set to either High, Low, or D on’t Care. Search for when the event goes true, goes false, or
staysvalidfor>,<,=,or≠ auserspecified time. Additionally, you can define one of the inputs
as a clock for synchronous (state) searches.
Setup & Hold Search for violations of u ser specified Setup and Hold times.
Rise/Fall Time Search f or rising and/or falling edges that are >, < , =, or ≠ a user specified time.
