PSPICE PRODUCT / TECHNICAL FEATURES
DESIGN ENTRY AND EDITING
• Use the advanced capabilities of OrCAD Capture schematic or Capture CIS, the world’s most
popular schematic entry system, to enter your designs
• Select from a library of over 20,000 parts for simulation, or choose from the large library of parts
within OrCAD Capture for general schematic entry
• Easily import existing PSpice designs, created from Schematics, into the OrCAD Capture / PSpice
environment
• Navigate through complex designs quickly with the hierarchical browser
• Create hierarchical block diagrams with automatic pin placement on hierarchical blocks
• Connect analog and digital components to reflect physical connections. The simulator automati-
cally manages the transitions between analog and digital domains
• Cadence Allegro
®
Design Entry HDL is also fully integrated with PSpice, including one-button
simulation and cross-probing
STIMULUS CREATION
• Invoke the interactive, graphical PSpice Stimulus Editor from within OrCAD Capture to define and
preview stimulus characteristics
• Access built-in functions that can be described parametrically, or draw piecewise linear (PWL)
signals freehand with the mouse to create any shape stimulus
• Create digital stimuli for signals, clocks, and buses; click-and-drag to introduce and
move transitions
ORCAD CAPTURE / PSPICE INTEGRATION
• Set up and run simulations, and cross-probe simulation results from OrCAD Capture
• Use the hierarchical netlister with parametric sub-circuits for faster netlisting of complex hierar-
chical designs
• Expanded simulations can be run in the background while design editing continues
• Create multiple simulation profiles and save them in the OrCAD Capture Project Manager,
allowing previous simulations to be recalled and run
• View simulation bias results directly on the schematic, including node voltages, pin and
sub-circuit currents, and device power calculations
SIMULATION CONTROL
• Perform and monitor simulations, view simulation messages and graphical results, view and edit
text files — all from a unified simulation environment
• Utilize analog analysis capabilities such as user-defined accuracy, automatic time-step control,
and proprietary convergence algorithms to control the simulation process
• Interactively trade off accuracy and simulation time by loosening tolerances and time steps
during non-critical periods of transient analyses, or by extending a transient analysis beyond
pre-specified end time
• Preempt the current simulation to immediately run another one, then return to complete the
preempted simulation later; control the queue of simulations waiting to be performed
