However, you will only be using some of the features as: OrCAD is very costly and probably the most comprehensive set of EE CAD tools currently available for the PC. You will be using OrCAD for Microsoft Windows. SE2P6 Engineering Applications (Anemometer Project) Project Supervisor: Dr Simant Prakoonwit 5ġ.4 DESCRIPTION OF YOUR SYSTEM The Electronic Engineering Division has been using CAD tools from OrCAD for many years. Its use is to save on lots of wires, in your design, which would connect back to the supply. Symbol to tie the connected node to a node termed VCC. SE2P6 Engineering Applications (Anemometer Project) Project Supervisor: Dr Simant Prakoonwit 4ĭescription A 220KΩ (220,000Ω) resistor labelled R1Ī 100nF (100*10-9 F) capacitor labelled C3Ī diode which has had its type field changed to OSCILLATOR and its label is D1 This is good practice to tell the schematic that you know nothing should be connected here IC's expect GND Click this to connect your components with wires Click this to place a DC power point in your circuit Click this to place no-connects on you circuit. Be careful, as there are lots of types of ground. 26 1.2 LIST OF SYMBOLSĭescription Place a part from the current library or to add libraries to your project Click this button to select the selection facility Click this to place a generic ground. Positions of components altered to help the autorouter. Screen dump of the PCB rats nest layout (inverted image). Adding a 2-pin power connector to your design. This tutorial assumes that you are familiar with Microsoft Windows, for example manipulating windows, printing, load, save and the mouse operations. This project contains both analogue and digital components. It then describes the generic process of simulation using Spice and finally describes a demonstration project that will be the theme for this tutorial. Firstly, this chapter describes the Computer Aided Design (CAD) tools available to you. This booklet will serve as invaluable reference material for the upcoming EA1 (anemometer) project and your electronic projects throughout your course.
