Provided that the display parameters are properly set, the researcher may view the simulated waveforms and update the parameter values on-line by running the rcvsim executable which will make repeated function calls to the WAVE display system. Alternatively, the waveforms, which are recorded to MIT format files, may be viewed at any time after completion of the simulation (off-line viewing) by directly running the wave executable file at the Linux prompt. An explanation on how to set the display parameters and caveats to on-line parameter updating are provided below. See also Examples 1-7 in Section 5.5 which illustrate how to view waveforms both on-line and off-line.
