ModelSim-Altera Software Q & A
Is the ModelSim-Altera Edition software the same as the ModelSim PE/DE software?
No, the ModelSim-Altera Edition software is licensed to support designs written in 100 percent VHDL and 100 percent Verilog language, and does not support designs that are written in a combination of VHDL and Verilog language, also known as mixed HDL. Mixed HDL support is available as options in the PE/DE version of ModelSim from Mentor Graphics. 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 Starter Edition software is the same as ModelSim-Altera Edition software except for two areas. ModelSim-Altera Starter Edition's simulation performance is lower than ModelSim-Altera Edition's, and has a line limit of 10,000 executable lines compared to the unlimited number of lines allowed in the ModelSim-Altera Edition software.
