Analyze Waveform Data
The Wave Inspector includes the following search capabilities:
Search
Description
Edge
Searches for edges (rising or falling) with a user-speci
fi
ed threshold level.
Pulse Width
Searches for positive or negative pulse widths that are >, <, =, or
≠
a user speci
fi
ed pulse width.
Runt
Searches for positive or negative pulses that cross one amplitude threshold but fail to cross a
second threshold before crossing the
fi
rst again. Search for all runt pulses or only those with a
duration >, <, =, or
≠
a user speci
fi
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 Don’t Care. Search for when the event goes true, goes false, or
stays valid for >, <, =, or
≠
a user speci
fi
ed time. Additionally, you can de
fi
ne one of the inputs
as a clock for synchronous (state) searches.
Setup & Hold
Search for violations of user speci
fi
ed Setup and Hold times.
Rise/Fall Time
Search for rising and/or falling edges that are >, <, =, or
≠
a user speci
fi
ed time.
