RE: [pci] pci board layout specifications

[Eric Pearson <epearson@lsil.com>]

Hello Marco....

Yes there are particular (well known?) layout specifications.
You can get them from "Chapter 4 Electrical Specifications" of the 
PCI Local Bus specification.

Of interest to you will be 
4.4 Expansion Board specifications
4.4.2.1 Decoupling
4.4.3 Physical Requirements
4.4.3.1 Trace Length Limits
4.4.3.3 Impedance
4.4.3.4 Signal Loading

+ Chapter 5 Mechanical Specification

You may be able to get this info from app notes for PCI interface chips.


Regards,...

Eric Pearson

Good morning,
I'm going to prototipe a PCI board with the PCI-bridge core on a Spartan 
2e for my thesis work.
I would like to know if there is some particular layout specification 
for the PCI signals (wire lenght, wire distance, low-R, ecc...)

Thank's!
