Altera ModelSim 10.3d | 1.2 Gb ModelSim-Altera Edition software only supports Altera gate-level libraries. The ModelSim-Altera Edition software includes the base features of ModelSim PE, including behavioral simulation, HDL testbenches, and Tcl scripting. However, ModelSim PE optional features are not supported in the ModelSim-Altera Edition software and the simulation performance of the ModelSim-Altera Edition software is slower than that of the ModelSim PE/DE software. ModelSim-Altera Edition Software • Recommended for simulating all FPGA designs (Arria®, Cyclone®, Stratix® series FPGA designs, and MAX® series CPLDs) • 33 percent faster simulation performance than ModelSim®-Altera® Starter Edition software • No line limitations
