probe_xreal :
A probe for an xreal-typed signal.

The probe_xreal primitive records the waveform of an xreal-typed signal into a file.

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). When recording in JEZ format, the parameter format defines whether the data are recorded in a binary (“jezbinary”) or ascii (“jezascii”) format. When recording in FSDB format, the parameters abstol and reltol set the error tolerance of recording the true waveform as an approximate piecewise-linear waveform. The parameters start and stop define when the recording begins and ends, respectively.
