ORCAD

OrCAD Capture CIS is a software tool used for circuit schematic capture. It is part of the OrCAD circuit design suite.

Capture CIS is nearly identical to the similar OrCAD tool, Capture. The difference between the two tools comes in the addition of the component information system (CIS). The CIS links component information, such as printed circuit board package footprint data or simulation behavior data, with the circuit symbol in the schematic. When exported to other tools in the OrCAD design suite, the data stored in the CIS is also transferred to the other tool. Thus, when a design engineer exports a schematic to the circuit board layout utility, the majority of the circuit elements have footprints linked to them. This saves time for the design engineer.

Capture CIS has the ability to export netlists, representative of the circuit schematic which is currently open, to the OrCAD simulation utility, PSpice. Capture CIS also exports a simulation configuration file, accessible through the simulation toolbar. This, coupled with the CIS, allows for quick simulations with data representative of how the circuit will behave. Capture may also export a netlist to the SPICE simulation utility.

Capture may export a hardware description of the circuit schematic that is currently open, either in Verilog or VHDL.

Capture also has the ability to export netlists to several different circuit board layout utilities, such as OrCAD Layout, Allegro, and others. When combined with the CIS, circuit board footprints are linked to this netlist. This, combined with the pin to pin interconnect description of the netlist, will open the correct part footprints, and, if the CIS data that CIS exported is correct, will connect all of the pads together with representative lines. This feature makes the circuit board design process easier for the design engineer.

Recent versions of capture also include a TCL/TK scripting functionality that allows users to execute a command through a command prompt. The command can be stored and replayed later. This allows users extensive customization and scripts can be written to automate any task possible though the graphical interface.

ORCAD PSPICE

Core PSpice is a SPICE analog circuit and digital logic simulation program for Microsoft Windows. The name is an acronym for Personal Simulation Program with Integrated Circuit Emphasis.

PSpice was initially developed by MicroSim and is used in electronic design automation. The company was bought by OrCAD, which was subsequently purchased by Cadence Design Systems.

PSpice was the first version of UC Berkeley SPICE available on a PC, having been released in January 1984 to run on the original IBM PC. This initial version ran from two 360 KB floppy disks and later included a waveform viewer and analyzer program called Probe. Subsequent versions improved on performance and moved to DEC/VAX minicomputers, Sun workstations, Apple Macintosh, and Microsoft Windows During its development, PSpice has evolved into an analog mixed signal simulator. The software, now developed towards more complex industry requirements, is integrated in the complete systems design flow in OrCAD and Cadence Allegro. It includes features such as analysis of a circuit with automatic optimization, encryption, a model editor, support for parameterized models, auto-convergence and checkpoint restart, several internal solvers, a magnetic part editor, and support for Tabrizi core model for non-linear cores.

Core The powerful, tightly integrated PCB design technologies include design capture, librarian tools, PCB editing/ routing, signal integrity (Professional), and optional circuit simulation. Easy to -use and intuitive, they offer exceptional value and future-proof scalability to the Cadence Allegro series of PCB design products
