Lattice Diamond design software offers leading-edge design and implementation tools optimized for cost sensitive, low-power Lattice FPGA architectures. Diamond is the next generation replacement for ispLEVER featuring design exploration, ease of use, improved design flow, and numerous other enhancements. The combination of new and enhanced features allows users to complete designs faster, easier, and with better results than ever before.
The latest version of Lattice Diamond software can always be downloaded from the Lattice Diamond Downloads page.
See the Lattice Diamond Versions list for feature updates and changes.

Lattice Diamond is the new flagship logic design environment for Lattice FPGA products. Diamond is available as a download from the Lattice website for both Windows and Linux. Once downloaded and installed, it can be used with either a free license or a subscription license. Diamond software only needs to be downloaded and installed once.
A free license can be requested from the Lattice website. This license provides access to many popular Lattice devices such as MachXO2, MachXO, and LatticeECP2 at no cost. It also includes Synopsys Synplify Pro for Lattice synthesis and Aldec Lattice Edition II mixed language simulation software.
A subscription license can be purchased which adds support for all Lattice FPGAs. It includes Synopsys Synplify Pro for Lattice synthesis and Aldec Lattice Edition II mixed language simulator. The subscription license also enables both the new Diamond software and existing ispLEVER software from a single license.
