In addition to supporting standard HDLs, ModelSim increases design quality and debug productivity. ModelSim’s award-winning Single Kernel Simulator (SKS) technology enables transparent mixing of VHDL and Verilog in one design. Its architecture allows platform-independent compile with the outstanding performance of native compiled code. The graphical user interface is powerful, consistent, and intuitive. All windows update automatically following activity in any other window. For example, selecting a design region in the Structure window automatically updates the Source, Signals, Process, and Variables windows. You can edit, recompile, and re-simulate without leaving the ModelSim environment. All user interface operations can be scripted and simulations can run in batch or interactive modes. ModelSim simulates behavioral, RTL, and gate-level code, including VHDL VITAL and Verilog gate libraries, with timing provided by the Standard Delay Format (SDF). ModelSim Overview Unified mixed language simulation engine for ease of use and performance Native support of Verilog, SystemVerilog for design, VHDL, and SystemC for effective verification of sophisticated design environments Fast time-to-debug, easy to use, multi-language debug environment Advanced code coverage and analysis tools for fast time to coverage closure Interactive and Post-Sim Debug available so same debug environment used for both Powerful Waveform compare for easy analysis of differences and bugs Unified Coverage Database with complete interactive and HTML reporting and processing for understanding and debugging coverage throughout your project Coupled with HDL Designer and HDL Author for complete design creation, project management and visualization capabilities Features Advanced Code Coverage ModelSim’s advanced code coverage capabilities and ease of use lower the barriers for leveraging this valuable verification resource. The ModelSim advanced code coverage capabilities provide valuable metrics for systematic verification. All coverage information is stored in the Unified Coverage DataBase (UCDB), which is used to collect and manage all coverage information in a highly efficient database. Coverage utilities that analyze code coverage data, such as merging and test ranking, are available. Coverage results can be viewed interactively, post-simulation, or after a merge of multiple simulation runs. Code coverage metrics can be reported by instance or by design unit, providing flexibility in managing coverage data. The coverage types supported include: Statement coverage Number of statements executed during a run Branch coverage Expressions and case statements that affect the control flow of the HDL execution Condition coverage Breaks down the condition on a branch into elements that make the result true or false Expression coverage The same as condition coverage, but covers concurrent signal assignments instead of branch decisions Focused expression coverage Presents expression coverage data in a manner that accounts for each independent input to the expression in determining coverage results Enhanced toggle coverage In default mode, counts low-to-high and high-to-low transitions; in extended mode, counts transitions to and from X Finite State Machine coverage State and state transition coverage Mixed HDL Simulation ModelSim combines simulation performance and capacity with the code coverage and debugging capabilities required to simulate multiple blocks and systems and attain ASIC gate-level sign-off. Comprehensive support of Verilog, SystemVerilog for Design, VHDL, and SystemC provide a solid foundation for single and multi-language design verification environments. ModelSim’s easy to use and unified debug and simulation environment provide today’s FPGA designers both the advanced capabilities that they are growing to need and the environment that makes their work productive.. Effective Debug Environment The ModelSim debug environment’s broad set of intuitive capabilities for Verilog, VHDL, and SystemC make it the choice for ASIC and FPGA design. ModelSim eases the process of finding design defects with an intelligently engineered debug environment. The ModelSim debug environment efficiently displays design data for analysis and debug of all languages. ModelSim allows many debug and analysis capabilities to be employed post-simulation on saved results, as well as during live simulation runs. For example, the coverage viewer analyzes and annotates source code with code coverage results, including FSM state and transition, statement, expression, branch, and toggle coverage. Signal values can be annotated in the source window and viewed in the waveform viewer, easing debug navigation with hyperlinked navigation between objects and its declaration and between visited files. Race conditions, delta, and event activity can be analyzed in the list and wave windows. User-defined enumeration values can be easily defined for quicker understanding of simulation results. For improved debug productivity, ModelSim also has graphical and textual dataflow capabilities.
