Allegro PCB Design Tutorials
This tutorial is intended for beginners in printed circuit board design who wish to complete a board using Cadence Allegro Tool. This tutorial is for Windows XP but most of the things should be easy to be extended for Linux or Unix. Those who had experience with one or more PCB design tool may skip this page. Others may like to get a general view of the design process which is follows:
OrCAD on windows 7 (64-bit)
NOTE: There is only one chance for you to install this software otherwise you have to either restore your system or have to install new copy of Windows for your system. Well,it took me so long to find out how I should crack this version of orcad cause the guys from shooters had written nearly nothing in their readme!Anyway,some of the steps might be unnecessary,but I strongly advise you do them all: 5.Go to the shooters folder in CD1 and copy the license_manager folder to where you installed the licence manager,replacing one file and adding another.
SPICE
Last modified: March 20 12 Dear all, my seminar at APEC in Orlando went very well. Thank you for attending this session.CMOS: Circuit Design, Layout, and Simulation, Third Edition Buy at Amazon.ca , Amazon.cn , Amazon.fr , Amazon.de , Amazon.it , Amazon.co.jp , Amazon.co.uk , Amazon.com , or many other websites around the world. o SPICE_CMOSedu.zip , Solutions_CMOSedu.zip , Silvaco_CMOSedu.zip , Cadence_IC61_CMOSedu.zip , Cadence_IC51_CMOSedu.zip , Figures_CMOSedu.zip , and Electric_CMOSedu.zip . § Tutorials from CMOSedu.com: Bad design , Cadence Tutorials , Circuit Tutorials , Electric VLSI Tutorials , LTspice Tutorials , and Silvaco EDA Tutorials . § Videos are located here . *These problems are made available, in addition to the textbook problems, but without written solutions (the solutions are not written up) since they would end up posted on the web.

SPICE - a brief overview
This document gives a brief overview of SPICE. The description is far from complete, as SPICE is a powerful circuit simulator with many capabilities. However, this document will serve as a start for students in introductory classes.
collector The bipolar junction transistor model is an adaptation of the integral charge control model of Gummel and Poon. The direct current model is defined by the parameters IS, NF, ISE (or C2), NE, IKF, and BF, which determine the forward current gain characteristics; IS, NR, ISC (or C4) , NC, IKR, and BR, which determine the reverse current gain characteristics; and VA (or VAF, forward Early voltage) and VB (or VAR, reverse Early voltage), which determine the output conductance for forward and reverse regions. Three ohmic resistances, RB, RC, and RE, are included, where RB is high current dependent.
NPN-BJT
This model of a bipolar NPN junction transistor according to Gummel and Poon consists of the call of the model "BJT_REV" with the additional parameter Type=1. The parameters of the model NPN2_REV are passed to the model "BJT_REV" unalteredly. Detailed Informations may be found at the documentation of the model "BJT_REV".
