Compound Waveforms
Specifying Simulation Output
Compound Waveforms
Eldo can generate compound waveforms. This is a group of waveforms containing results of
several simulations for the same “node.” They can be generated from multiple-run sweep
analyses specified for example by .STEP or .ALTER commands.
For an example, the EZwave output in Figure 8-1 shows three waveforms, each corresponding
to a .ALTER:

Plotting an Analog Signal as a Digital Bus
To enable the plotting of an analog signal as a digital bus, a setup command is required
(.DEFPLOTDIG) to be used in conjunction with the VDIG parameter of the .PLOT command.
.DEFPLOTDIG VTH1=2.2 VTH2=2.7
.PLOT TRAN VDIG(n2)
When .DEFPLOTDIG is used in conjunction with .PLOT VDIG, the signal node n2 is plotted
as a digital curve and will only have values of “1” or “0”.
• .DEFPLOTDIG [VTH[1]=VAL [VTH2=VAL]]
