This document provides practical, common guidelines for incorporating PCI Express interconnect
layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10-
layer or more server baseboard designs. Guidelines and constraints in this document are intended
for use on both baseboard and add-In card PCB designs. This includes interconnects between PCI
Express devices located on the same baseboard (chip-to-chip routing) and interconnects between
a PCI Express device located “down” on the baseboard and a device located “up” on an add-In
card attached through a connector.
This document is intended to cover all major components of the physical interconnect including
design guidelines for the PCB traces, vias and AC coupling capacitors, as well as add-In card
edge-finger and connector considerations. The intent of the guidelines and examples is to help
ensure that good high-speed signal design practices are used and that the timing/jitter and
loss/attenuation budgets can also be met from end-to-end across the PCI Express interconnect.
However, while general physical guidelines and suggestions are given, they may not necessarily
guarantee adequate performance of the interconnect for all layouts and implementations.
Therefore, designers should consider modeling and simulation of the interconnect in order to
ensure compliance to all applicable specifications.
The document is composed of two main sections. The first section provides an overview of
general topology and interconnect guidelines. The second section concentrates on physical layout
constraints where bulleted items at the beginning of a topic highlight important constraints, while
the narrative that follows offers additional insight.
The Lite Evaluation/Demonstration Kit is intended to illustrate use of the
AN3042. The AN3042 is compliant to the PCI 2.1 Local Bus specification.
Included in the kit is a PCI add-In card, Windows drivers, demonstration
applications, and documentation of the hardware and software provided. The
microprocessor used on the PCI add-In card is the Motorola MPC860. The
applications themselves serve as documentation on how to interface with the
drivers, and also may be used to test the AN3042 on the user s prototype board.

"Window Tabs" (WndTabs) is an add-In for Microsoft Visual C++ v6 family of
products (VC5, VC6, eVC3, eVC4 and Visual Fortran). It adds a docking bar of
tabs reflecting all of the opened windows in the workspace. You can switch
between the windows by simply clicking on the tab.
The tabs have extensive right-click context menus full of useful functions.

ResOrg - Manage and Renumber Resource Symbol IDs
Introduction
The Resource ID Organiser (ResOrg for short) is an add-In for Visual C++ designed to help overcome one of the most annoying (and unnecessary) chores of developing/maintaining Windows applications - maintaining resource symbol ID values.
