CIRCUIT DESIGN

technical-training

Integrated circuit design, or IC design, is a subset of electrical engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography. We offers courses for electronic engineering using world renowned software OrCAD, an electronic design automation. The courses help students design circuits, present the graphical representation of electronic components and interconnections, circuit simulation & analysis on standard parameters including time, temperature and frequency, and printed circuit board design involving exact physical components.

OrCAD Capture is a market leading software tool used for circuit schematic capture, a schematic design application. It is part of the OrCAD circuit design suite.
It is used to draw a circuit on the screen, known formally as schematic capture. Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor.

OrCAD Capture offers great flexibility compared with a traditional pencil and paper drawing, as design changes can be incorporated and errors corrected quickly and easily.
It helps you do fast and intuitive schematic design entry for PCB development or analog simulation using Pspice. Capture is easy-to-use and powerful, and the most widely used schematic design solution.
Capture supports both flat and hierarchal designs from the simplest to the most complex, and it can reduce the amount of time spent researching needed parts.

At CADD Centre, we help you master the following capabilities of OrCAD Capture:

  • Effective usage of its large library of schematic symbols. The software provides access to more than two million parts, offering greater flexibility when choosing design components.
  • Component Information System of Capture which automatically synchronizes and validates externally sourced part data
  • The seamless bi-directional integration with OrCAD PCB Editor that boosts schematic editing efficiency of complex designs through hierarchical and variant design capabilities. CIS also promotes the use of preferred, current parts to accelerate the design process and reduce project costs.

  • You will know how to draw circuits by creating electronic diagram, or electronic schematic of the designed electronic circuit.
  • You will know how to back annotate layout changes, make gate/pin swaps, and change component names or values from board design to schematic
  • You will know how to search, identify, and populate the design with preferred parts; and access company component databases and part information.

OrCAD PSpice, short for Simulation Program for Integrated Circuit Engineering, simulates the captured circuit.
You can draw an electronic circuit on the computer using Capture and simulate it with PSpice using specific models for your devices to analyze its behavior in many ways and confirm that it performs as specified.

A full-featured, native analog and mixed-signal circuit simulator, OrCAD PSpice is the de-facto industry-standard Spice-based simulator for system design. It simulates complex mixed-signal designs containing both analog and digital parts, and it supports a wide range of simulation models such as IGBTs, pulse width modulators, DACs, and ADCs.
PSpice also allows users to design and generate simulation models for transformers and DC inductors. The software is now developed towards more complex industry requirements and is integrated in the complete systems design flow in OrCAD and Cadence Allegro.

At CADD Centre, we help you master the following capabilities and features of OrCAD PSpice:

  • 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.
  • Scalability options including PSpice Advanced Analysis capabilities and integration with MathWorks MATLAB Simulink for co-simulation.
  • Advanced capabilities such as temperature and stress analysis, electro-mechanical simulation, worst-case analysis, Monte Carlo analysis, and curve-fit optimizers help engineers design high-performance circuits that are reliable and withstand parameter variation.
  • Determines which components are over-stressed using Smoke analysis or observes component yields using Monte Carlo analysis to prevent board failures
  • MATLAB Simulink interface allows system-level interfaces to be tested with actual electrical designs emulating real-world application
  • PSpice’s built-in mathematical functions and behavioral modeling techniques that enable fast and accurate simulation of designs with efficient debugging.

  • You will know how to start a project, draw a schematic, and simulate circuit and generate graph data.
  • You will know how to draw schematics using PSpice with data on a voltage source, components, wires, and a ground.
  • You will know how to draw a full circuit, using wires, adding a ground, and changing the value of a part. You will also know how to name/rename your parts
  • You will know how to label nodes, and simulate your circuit using bias point/DC calculations; DC Sweep on input source; parametric sweep for resistance; AC sweep/frequency domain simulation, transient analysis or time domain simulation and ultimately, graphing in PSpice.

Besides, it enhances your design capability with features like full 3-D viewing of the design, “flip-board” viewing/editing, and new DRCs.
OrCAD PCB Editor provides a powerful and flexible set of floor planning tools and shape-based shove/hug interactive etch creation/ editing. Interactive, shape-based, any-angle, push/shove routing allows designers to quickly solve interconnect challenges.
Its dynamic shape capability offers real-time copper pour plowing/healing functionality during placement and routing iterations.


  • Enhanced Arc Editing: It is specifically designed for editing clines with curved corners. This function can be used to change the radius of an existing arc, convert a corner vertex point to an arc, slide segments tangent to an arc(s), automatically select or preserve one or both arcs, and slide straight segments that are connected to pins and vias.
  • Multi-Line Generator: This feature allows users to begin the group route in open space and experiment with different parameters. A user interface controls the quantity of lines, line width, line to line space, and control trace.
  • Via List DRC: It ensures alignment between the vias lists referencing net and region objects against the actual physical vias used in the design.
  • Via List Viewer: It now supports a graphical view of the vias associated with the respective physical CSet. Color selection, visibility, and data tip controls are available in the draw options tab.
  • 3-D Viewer: This 3-D environment supports several filtering options; camera views; graphic display options such as solid, transparency and wireframe; and mouse driven controls for pan, zoom and spinning the display. 3-D viewing is also supported in pre-selection mode, making it possible to display HDI via structures or isolated sections of the board.
  • Flip Design: Designers can now view the layout of the PCB from the bottom side. Flip Design is not just limited to viewing, as design edits such as moving silkscreen text can be performed while in this mode. When Flip Design mode is invoked, there are indicators in the canvas advising this mode is active.
  • Enhanced Pad Entry: The interactive etch edit environment improves the transitioning of clines exiting and entering a pad stack. The enhanced pad entry works on circle, rectangle, and oblong pads by exiting perpendicular to a pad edge, or exiting out a radius at an angle that does not produce an acute angle.
