ModelSim - powerful, cost-effective simulation
VHDL, Verilog, and SystemVerilog design constructs
ModelSim packs an unprecedented level of verification capabilities into a cost-effective HDL simulation solution. In addition to supporting standard HDLs, ModelSim increases design quality and debug productivity.
A more intelligent GUI
An intelligently engineered GUI makes efficient use of desktop real estate. ModelSim offers a highly intuitive arrangement of interactive graphical elements (windows, toolbars, menus, etc.), making it easy to view and access the many powerful capabilities of ModelSim. The result is a feature-rich GUI that is easy to use and quickly mastered. ModelSim redefined openness in simulation by incorporating the Tcl user interface into its HDL simulator. Tcl is a simple but powerful scripting language for controlling and extending applications.
The ModelSim GUI delivers highly productive design debug and analysis capabilities as well as project and file management.
