Introduction
As PCI Express applications have emerged, the LatticeECP2M™ FPGA family has become a well-suited solution
for many system designs. The features of the LatticeECP2M PCI Express Solutions Board can assist engineers
with rapid-prototyping and testing their designs. The board is an enhanced form-factor of the PCI Express add-in
card specification. It allows for full x1 form-factor compliance and x4 is available for demonstration purposes with
some non-standard form-factor issues. The flexibility to use the same board to demonstrate both x1 and x4 config-
urations is accomplished by simply changing the mounting hardware. The board has several debugging and ana-
lyzing features for complete evaluation of the LatticeECP2M device. This guide is intended to be referenced in
conjunction with evaluation design tutorials to demonstrate the LatticeECP2M FPGA.
This user’s guide describes the LatticeECP2M PCI Express Solutions Board featuring the LatticeECP2M
LFE2M50-FF672 FPGA. The stand-alone evaluation board provides a functional platform for development and
rapid prototyping of applications that require high-speed SERDES interfaces to demonstrate PCI Express capabili-
ties using an add-on card form-factor. The board is manufactured using standard FR4 dielectric and through-hole
vias. The nominal impedance is 50-ohm for single-ended traces and 100-ohm for differential traces.

Features
• PCI Express x1 and x4 edge connector interfaces
• Allows demonstration of PCI Express (x 1and x4) interfaces
• Allows control of SERDES PCS registers using the Serial Client Interface (ORCAstra)
– x1 is form-factor compliant and will fit a standard PC-equipped PCI Express motherboard socket
– x4 is non-compliant but will demonstrate x4 functionality by a simple change to the hardware
