STEP 2 - Install each ispLEVER Classic Module

Starting with the ispLEVER Classic Base Module, unzip the downloaded file, then double-click the extracted file and to start the installation procedure. You can also download the installation guide from the Documentation tab on this page and read it for more detailed instructions and options.

For Windows 10 — Download and install the service pack enabling Windows 10 support. Please follow installation instructions in the readme.txt file.

Licensing

STEP 3 - Purchase/Renew ispLEVER Classic License

The ispLEVER Classic license enables users to design and optimize solutions for CPLD and Legacy devices.

To purchase an ispLEVER Classic license, please go to the Online Store or contact a local sales representative or distributor.

If you have purchased a Software license and received a Software Serial Number, please go to our Subscription licensing form.

Version History

ispLEVER Classic 2.1

  • Replaced Aldec™ Active-HDL™ with Mentor® ModelSim® Lattice FPGA Edition. Active-HDL Lattice Edition is still supported but not included.

ispLEVER Classic 2.0

Lattice Synthesis Engine (LSE)

  • Support added for Mach4000 CPLD family. LSE will be selected for the synthesis tool, by default, for new projects targeting these families. Existing projects will continue to use the synthesis tool previously used by that project. For Mach4000 CPLD, user can switch between LSE and Synopsys Synplify Pro.

Aldec Active-HDL Simulation – updated version to 10.1
