Spice based A/D mixed-mode simulation
Simulation at your fingertips, with powerful Spice based A/D mixed mode simulation
integrated into the Pulsonix design environment.
Fully integrated into the Pulsonix design environment, Pulsonix Spice is an advanced, mixed-mode
simulation package that out-performs many of the other Spice tools on the market.
A comprehensive selection of analysis functions may be applied to
plotted waveform data. At the click of a mouse the RMS, rise and fall time, -3dB
point or many other functions can be calculated and displayed
alongside the graph legend.
Within the Schematic, post-simulation 'random probing' is available. Graphs of circuit voltages, currents and
device powers can be created simply by clicking on a point on the schematic, avoiding any need to re-simulate
each time an additional measurement is required.
Analysis Modes
A range of Analysis modes are available in Pulsonix-Spice:-
- Operating Point : reports circuit voltages, currents and device operating parameters Analysis over time.
- Transient : small signal analysis of the circuit, linearised about its operating point.
- AC : includes sweeps: Frequency (as standard SPICE), Device (E.g. resistor or capacitor
value), Model parameter, Global parameter, Temperature, Single step Monte Carlo (repeats
analysis while applying component tolerances).
- DC : DC solution similar to AC analysis
- Noise : 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
- Transfer Function : Similar to AC but calculates response to a single output from all sources.
- Real Time Noise : An extension of transient analysis, applies noise generators, and
allows 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.
