CADENCE PSPICE A/D & PSPICE ADVANCED ANALYSIS
5
MIXED ANALOG / DIGITAL SIMULATION
• PSpice automatically recognizes A-to-D and D-to-A connections, and properly processes them by
inserting interface sub-circuits and power supplies
• Integrated analog and event-driven digital simulation engines improve simulation speed without
loss of accuracy
• Single graphical waveform analyzer displays mixed analog and digital simulation results on the
same time axis
• Digital functions support five logic levels and 64 strengths, load-dependent delays, and hazard /
race checking
ANALOG ANALYSIS
• Explore circuit behavior using basic DC, AC, noise, and transient analysis
• View node voltages, pin currents, and power consumption or noise contributions of individual
devices
• Include specific local temperature effects on individual devices for more accurate analysis
• Show circuit behavior variations as components change, via parametric, Monte Carlo, and worst-
case analysis
DEBUGGING AND CONVERGENCE
• CHECKPOINT RESTART: Store simulation states at various time-points and then restart simulations
from any of the simulation state. This saves time. Designer can modify simulation settings and
design parameters before starting a simulation from pre-recorded time-state.
• AUTO-CONVERGENCE: Automatically change tolerances limits of convergence to make the
design converge. Designer can use this option to get convergence and then fine tune simula-
tions by further modifying simulator options. This option is recommended for Power Electronic
Designs.
• ASSERTIONS: Use special parts to insert error and warning conditions for simulator to flag the
conditions as the simulation progresses.
