LatticeXP2 Brevia 2 Evaluation Board
This section describes the features of the LatticeXP2 Brevia 2 Evaluation Board in detail.
Overview
The LatticeXP2 Brevia 2 Evaluation Board is a complete development platform for the LatticeXP2 FPGA. The
board includes on-board SRAM and SPI Flash memory, and SPI microcontroller communication interfaces, a USB
port, and an expansion header to support test connections.

Demo_LatticeXP2_Brevia_SoC is provided as Demo_LatticeXP2_Brevia_SoC.s. The assembler and simulator
are command line applications. The tools display their invocation syntax if they are started without command
line parameters.
fastest way to update the PROM contents is to use the Diamond Memory Initialization tool. The tool updates
the PROM contents without modifying the connectivity of the design.
Launch the Memory Initialization tool, and select the isp8_prom component, choose the new memory initializa-
tion file, click on the Apply Changes button, and save the new NCD file.
