Setting Up An Analysis
DC Analysis
• .DC followed by the parameter TIME={time} performs a DC analysis during a transient
analysis. The transient analysis is stopped at each time specification, a true DC analysis
is performed, then the transient analysis continues.
DC sweeps can be nested up to three levels deep. For each value of the third level variable, the
second level variable is swept through its specified range. For each value of the second level
variable, the first level variable is swept through its specified range.
DC Analysis Results
For DC sweeps, the simulation output will contain tables of DC transfer voltages and currents
available in the ASCII .chi file or binary waveform output.
Example output in the .chi file from a .PRINT statement:
0**** DC TRANSFER CURVES TEMPERATURE = 27.000 DEG C
