Lattice Semiconductor offers a wide array of embedded control products and supporting accessories for them. One such accessory is their HW-USBN-2B programming cable, which aids in-system programming of Lattice devices via their Diamond/IsvPM software system. We’ve had some questions recently regarding licensing for this software - where do you get it, how much is it, and do you need to renew it?
Fortunately, the answer to all of that is “no licensing required.” The software is included with all of these tools and can be freely downloaded from Lattice’s website here: Lattice FPGA Software Library. Instructions for using the software can be found in the product’s user guide, available for download via this link: Lattice Programming Cable User Guide (PDF Download).
