Setup
Setup Time is the time between the mid reference level crossing of the clock source (Source1) and the closest previous mid
reference level crossing of the data source (Source2). The crossings (edges) may be configured to be rising, falling or either.
The application calculates this measurement using the following equation:
Where:
T Setup is the setup time.
T Main is the Main input (clock) Mid reference crossing time in the specified direction.
T 2nd is the 2nd input (data) Mid2 reference crossing time in the specified direction.
Skew
Skew is the time between the mid reference level crossing on Source1 to the mid reference level crossing on Source2. The
direction of the edge crossing is configurable.
The application calculates this measurement using the following equation:
Where:
T Skew is the timing skew.
