probe_period :
A period probe for a clock signal.
The probe_period
primitive measures the period of an xbit-typed periodic clock input (in
) and records its waveform into a file. The primitive uses a clk_to_period
primitive to measure the period of in
.
The parameter filename
sets the name of the waveform file, of which extension determines the waveform format (e.g. “.jez” for JEZ and “.fsdb” for FSDB). In case of recording in JEZ format, the parameter format
defines whether the data are recorded in a binary (“jezbinary”) or ascii (“jezascii”) format. The parameters start
and stop
define when the recording begins and ends, respectively.
