Powerful Spice based A/D mixed mode simulation integrated into the Pulsonix design environment.

The Pulsonix Spice Analysis Modes

Operating Point	Finds steady state bias point and produces report of circuit voltages, currents and device operating parameters Analysis over time. Provides voltage, current and power at all nodes or devices.
Transient	Performs a small signal analysis of the circuit linearised about its operating point.
AC	Operates in one of six modes: Frequency sweep. (As standard SPICE) Device sweep. (E.g. resistor or capacitor value) Model parameter sweep Global parameter sweep Temperature sweep Single step Monte Carlo sweep (repeats analysis while applying component tolerances).
DC	Repeats DC solution using any of the sweep modes, except frequency, described for AC analysis.
Noise	Performs a small signal noise analysis of the circuit linearised about its operating point. Calculates total noise at a nominated output and the contributions from every noisy device. Operates in any of the six modes described for AC analysis.
Transfer Function	Similar to AC but calculates response to a single output from all sources. Operates in any of the six modes described for AC analysis.
Real Time Noise	An extension of transient analysis, applies noise generators to all noisy devices with a magnitude calculated using the same equations as for small signal noise. Allow noise plotting in real time.
Sensitivity	Calculates sensitivity of circuit components and model parameters to a specified circuit parameter.
Pole-Zero	Finds the AC transfer function of a circuit in terms of its pole and zero locations.
