probe_value :
A probe for measuring the values of an xreal-typed signal at triggering events.
The probe_value
primitive measures the value of an xreal-typed signal in
at the specified triggering events and records the results in a table format to a text file named by the parameter filename
.
The measurement can be triggered either internally or externally depending on the value of the parameter period
. When period
is greater than 0, the measurement is triggered internally at a period of period
after an initial delay of delay
. When period
is 0, the change is triggered externally whenever the trig
input changes to a different value.
The primitive can also measure and record the values of multiple inputs at once. In this case, the parameter num_in
defines the number of inputs provided to in
.
