Lattice recommends migrating legacy designs to newer hardware architectures.
After submitting your request, Lattice typically sends a license file (usually named license.dat) to your registered email address. This file is not a standalone installer; it is a configuration file that the software references. You must save this file to a local directory on your machine. For most users, the standard practice is to create a folder within the Lattice installation directory specifically for license storage.

As of April 2026, for ispLEVER Classic . This software is the legacy design environment for mature programmable products like the ispMACH 4000 series CPLDs.
If you need short-term access to modify an old design or retrieve files, Lattice offers a temporary extension.
ISPLEVER Classic is a legacy electronic design automation (EDA) software suite created by Lattice Semiconductor. While newer design suites like Lattice Diamond handle modern Field Programmable Gate Arrays (FPGAs), ISPLEVER Classic remains mandatory for targeting older, mature architectures. Supported Device Families
The free Base License does not support every chip ever made by Lattice, but it covers a vast selection of classic, low-density devices. If you are using the free license, you can target the following device families:
If your project allows for it, or if you are unable to secure a license, you may consider alternative methods to handle legacy CPLDs:
Getting a free license for Lattice Semiconductor’s legacy software can be tricky, as the company shifted many of its "Classic" tools to a paid subscription model several years ago. However, for certain devices and legacy workflows, there are still ways to access the software or migrate to free modern alternatives.
