Download Demo Designs
The counter demo is preprogrammed into the Breakout Board, however over time it is likely your board will be mod-
ified. Lattice distributes source and programming files for demonstration designs compatible with the Breakout
Board. The demo design for the 1200ZE version of the board is available on the web. Use the same design files for
MachXO2-7000HE. Change the device in the Diamond Software tool and re-run the process flow to generate the
JEDEC for MachXO2-7000HE. The description below references the 7000HE version.
To download demo designs:
1. Browse to the Lattice Breakout Board Evaluation Kits web page (www.latticesemi.com/breakoutboards) of the
Lattice web site. Select MachXO2 Breakout Board Demo Source and save the file.
2. Extract the contents of MachXO21200ZEBreakoutBoardDemoDesignSource.zip to an accessible location
on your hard drive.
3. Open the Project in the Diamond Design Software and change the device to MachXO2-7000HE-4TG144C.
4. Run the Process Flow and regenerate the JEDEC file.
