A PSpice circuit description file (*. Ashampoo Burning Studio 2012 Full Version. cir) contains the configuration data for circuit simulation with the simulator. The simulator processes such files, and generates a simulation result file (*.out), as well as a binary probe data file (*.dat) for viewing waveforms. PSpice Circuit files are typically generated by or other application, and may also be entered manually in a. The circuit file contains the component netlist, simulation options, analyses statements, and the output control statements. The component netlist comprises a list of all circuit elements, along with the node names connected to their terminals. The netlist topology is converted into an equivalent matrix which is solved to find the circuit state, and is also used to simulation output file. Contents • • • • • • • • • • • • Types of analyses [ ] The type of simulation performed by PSpice depends on the source specifications and control statements.

The analyses usually executed in PSpice are listed below. DC Analysis [ ] It is used for circuits with time–invariant sources (e.g.

Steady-state dc sources). It calculates all nodal voltages and branch currents over a range of values. The types of dc sweep analyses and their corresponding.(dot) commands are described below: • Linear sweep:.DC [LIN] • Logarithmic sweep:.DC • Sweep over List of values:.DC LIST * All these sweep types can also be nested by adding another set of parameter name and values at the end. Transient Analysis [ ] It is used for circuits with time variant sources (e.g., sinusoidal sources/switched dc sources). It calculates all nodes voltages and branch currents over a time interval and their instantaneous values are the outputs. The corresponding.(dot) command is as follows:.TRAN [no-print value [step ceiling value]] [SKIPBP] AC Analysis [ ] It is used for small signal analysis of circuits with sources of varying frequencies.
