  1. OrCAD
  2. OrCAD Capture
  3. PSpice
  4. OrCAD Layout
  5. Proteus
  6. Multisim


OrCAD family products offer a total solution for your core design tasks: schematic- and VHDL-based design entry; FPGA and CPLD design synthesis; digital, analog, and mixed-signal simulation; and printed circuit board layout. OrCAD family products are a suite of applications. It built around an engineer’s design flow—not just a collection of independently developed point tools.

OrCAD Capture: –

It is a versatile design entry product. You can use it to create schematics for analog or mixed signal designs, printed circuit board layout designs, and programmable logic designs. First, create your flat or hierarchical design in the schematic page editor. After that use Capture’s tools to quickly annotate it. Now prepare it for the next stage of development.

PSpice: –

It is a simulation program that models the behavior of a circuit. It simulates analog only circuits, whereas PSpice A/D simulates any mix of analog and digital devices. Used with OrCAD Capture for design entry, you can think of PSpice as a software-based breadboard of your circuit that you can use to test and refine your design before manufacturing the physical circuit board or IC.

OrCAD Layout: –

The OrCAD Layout place-and-route tool offers PCB designers the power and flexibility to create and share PCB data and constraints across the design flow. It is an ideal tool for individuals and small-to-medium design teams creating printed circuit boards from prototype to production.


The Proteus Design Suite is wholly unique in offering the ability to co-simulate both high and low-level micro-controller code in the context of a mixed-mode SPICE circuit simulation. With this Virtual System Modelling facility, you can transform your product design cycle, reaping huge rewards in terms of reduced time to market and lower costs of development. If one person designs both the hardware and the software then that person benefits as the hardware design may be changed just as easily as the software design. In larger organizations where the two roles are separated, the software designers can begin work as soon as the schematic is completed; there is no need for them to wait until a physical prototype exists.


Multisim equips educators, students, and professionals with the tools to analyze circuit behavior. The intuitive and easy-to-use software platform combines schematic capture and industry-standard SPICE simulation into a single integrated environment. Multisim abstracts the complexities and difficulties of traditional syntax-based simulation. So you no longer need to be an expert in SPICE to simulate and analyze circuits.
provides an easy and intuitive platform to design printed circuit boards (PCBs). The flexible Ultiboard design environment offers automated functionality for speed and manual techniques for precise control. With complete integration to NI Multisim, Ultiboard helps you optimize PCB design. Quickly prototype whether for professional designs or academic research.
