Specifying Simulation Output
Examples of Defining Waveforms
.EXTRACT LABEL = A MAX(V(1))
.EXTRACT LABEL = B MAX(V(2))
.STEP PARAM P1 1 3 1
.DEFWAVE SWEEP my_wave = MEAS(a) + MEAS(b)
.end
Example using the SIGMA function to sum various items (numbers, parameters or output
quantities); when items are output quantities, wildcards are accepted:
.EXTRACT dc SIGMA(v(*),1.0,'p1+2')
.DEFWAVE tran star3=SIGMA(ISUB(X2*.g),V(E*))
Example of using the PWL function:
v1 1 0 pwl ( 0 0 10n 10)
r1 1 0 1
.defwave tran foo = pwl(0,0,20n, meas(ex))
.extract label = ex yval(v(1),5n)
.tran 1n 10n
.plot tran w(foo)
.end
Example of using the PWL, PWL_CTE and PWL_LIN functions.
v1 1 0 pwl ( 0 0 10n 10)
r1 1 0 1
.defwave tran f1 = pwl(5n,0,7n,5,8n,5,9n,1)
.defwave tran f2 = pwl_cte(5n,0,7n,5,8n,5,9n,1)
.defwave tran f3 = pwl_lin(5n,0,7n,5,8n,5,9n,1)
.defwave tran f4 = pwl_lin(5n,0, 5n, 5)
.defwave tran f5 = pwl_lin(0n, 5)
.extract label = ex yval(v(1),5n)
.tran 1n 10n
.plot tran w(f1) w(f2) w(f3) w(f4) w(f5)
.end
The plot obtained from the netlist is shown in Figure 8-2. The wave f4 demonstrates how to plot
vertical waves with the .DEFWAVE command.
