Description

Determines what interval list collection is recorded at target clock location by performing signal transmission of original interval list collection between base and target clock locations. If any signaled interval ends up with start time after its stop, the interval is excluded from signaled list. If neighboring signaled intervals overlap or abut, they are replaced by single interval in signaled list.

Object Model

Public Properties

BaseClockLocation	The base clock location, which is a point from VGT.
OriginalCollection	The original interval list collection.
SignalDelay	The Signal delay definition, which includes signal transmission, time delay convergence and signal path reference system.
SignalSense	The direction of the signal, whether you are Transmitting or Receiving from the Base Clock Location.
TargetClockLocation	The target clock location, which is a point from VGT.

Example

Create and configure signaled event interval collection.
