Specify a signal name matching one that you configured when you generated the
object. The signal must be configured as a data signal.
The bit width of the data type must match the bit width of the captured signal. This
size is the width you specified for the port on the generated IP.
The function supports these data types, depending on the bit width of the captured
signal: boolean, uint8, int8,
uint16, int16, half,
uint32, int32, single,
uint64, int64, double, and
numerictype.
