PROBE WINDOWS
• Choose from an expanded set of mathematical functions to apply to simulation output variables
• View simulation results in multiple waveform windows
• Select waveforms by name or by marking a net, pin, or part in the schematic
• Utilize cross-probing markers once and they stay with the analysis. As you change and
re-simulate the design, the marked waveforms appear after each simulation
• View continuous, real-time “marching waveforms” as simulation progresses
• Copy and paste high-resolution, scalable waveforms into other applications for producing
documentation
• Create plot window templates and use them to easily plot complex functions of signals, just by
placing markers on desired pins, nets, and parts in the schematic
• Measure performance characteristics of your circuit using built-in measurement functions or
create your own measurements
DATA DISPLAY
• Plot both real and complex functions of circuit voltage, current, and power consumption
including Bodé plots for gain and phase margin and derivatives for small-signal characteristics
• Display Fourier transforms of time domain signals or inverse Fourier transforms of frequency
domain signals
• Vary component values over multiple runs and quickly view results as a family of waveforms with
parametric, Monte Carlo, and worst-case analysis
• Plot waveform characteristics, such as rise time versus temperature or supply voltage, using
parametric analysis
• Create histograms after Monte Carlo analysis to display the distribution of a characteristic, such
as overshoot
ACCURATE INTERNAL MODELS
• Large variety of built-in models adds flexibility to simulations, most include temperature effects
• Shipped models include R, L, C, plus:
- Built-in IGBTs
- Seven MOSFET models, including industry standard BSIM4, BSIM3v3.2 and the new EKV 2.6
model
- Five GaAsFET models, including Parker-Skellern and TriQuint TOM-3 models
- Two Bipolar models, including Gummel Poon and Mextram
- Nonlinear magnetic models complete with saturation and hysteresis
- Transmission line models that incorporate delay, reflection, loss, dispersion, and crosstalk
- Digital primitives, including bidirectional transfer gates with analog I/O models
• Device Equations Developer’s Kit (DEDK) allows implementation of new internal model equations
which can be used with PSpice*
*DEDK is only available with a separate legal agreement through OrCAD Marketing. DEDK is
intended for use by experienced device physicists and requires knowledge of C programming.
