Complete PCB Design Using OrCad Capture and Layout

This chapter explains what you did when making the simple design in Chap. 2 and why. It also introduces and describes the Layout tool set in greater detail so that you will be well equipped to lay out more complicated boards in Chap. 9.
When you set up your project by following the File ? New ? Project menu path, there were five options to choose from: a project, a design, a library, a VHDL file, or a Text file. The options we will be most interested in are projects and libraries, and we will be looking at those in great detail throughout the book. VHDL files are used in field programmable gate array projects and will not be discussed here. A text file is simply a text file (for making project notes for example).
After you selected the New Project option to begin setting up your project, there were four more options available to you in the New Project dialog box: Analog or Mixed-Signal A/D, PC Board Wizard, Programmable Logic Wizard, or Schematic. A flow diagram of these options and suboptions is shown in Fig. 3-1 (see also Fig. 2-2). Analog or Mixed-Signal A/D is used to simulate analog and/or digital circuits using PSpice. PSpice will be used to develop and test models (Chap. 7), perform circuit simulations (Chaps. 7 and 9), and to simulate transmission lines (Chap. 11). For now we will be working mostly with...
