Active-HDL Lattice Edition Libraries for CPLD, SPLD, and Mature FPGAs

If you have already installed Lattice Diamond or ispLEVER/Pro Version 7.1 or later with Active-HDL Lattice Edition (LE), and now wish to install and use ispLEVER Classic to design CPLDs like the ispMACH 4000, you can configure ispLEVER Classic to use the full-featured Active-HDL Lattice Edition (LE) simulator.

The library resources for SPLD, CPLD, and mature FPGA device families supported in ispLEVER Classic are not installed with Lattice Diamond or ispLEVER.  Active-HDL Lattice Web Edition (LWE) is distributed as a web download for ispLEVER Classic or ispLEVER Starter. It supports single HDL simulation and installs library support devices covered by ispLEVER Classic/Starter only. Active-HDL Lattice Edition (LE) is distributed with Lattice Diamond or all ispLEVER Versions 7.1 or later (ispLEVER/Pro) and provides Verilog/VHDL co-simulation and a higher performance/capacity engine for simulation. LWE should only be used of LE is not available.

Use the procedure below to install and configure Active-HDL Lattice Edition simulation libraries for CPLD, SPLD, and mature FPGAs.

1. Review the Lattice Diamond or ispLEVER/ispLEVER PRO license and environment.
   To ensure ispLEVER Classic and Active-HDL Lattice Edition features are enabled, configure the system environment to use the Lattice Diamond or ispLEVER/PRO license file provided to you. The Lattice Diamond or ispLEVER/PRO license file will enable both ispLEVER Classic and Active-HDL (LE).
    
2. Unpack Classic libraries and library configuration (library.cfg) into the Lattice Diamond or ispLEVER/PRO install tree.
   Click here for a ZIP archive of the libraries and library configuration file. Unpack to the <install path>active-hdlVlib directory. Several pre-compiled Active-HDL libraries for SPLD, CPLD, and mature FPGAs are added. The library.cfg file is replaced with one that covers all device families supported by ispLEVER Classic, Lattice Diamond, and ispLEVER/PRO.
    
3. Update Active-HDL Install Path within ispLEVER Classic Project Navigator.
   
   • Run ispLEVER Classic Project Navigator.
   • Choose Options > Environment...
   • The Environment Options dialog appears.
   • Choose the Directories tab. Click the ... button.
     The Set Active-HDL Install Path dialog appears.
   • Browse to the <install path>active-hdl directory and click OK.
   • Click OK to accept the Active-HDL directory.
