Thecombination of industry-leading performance and capacity with thebest integrated debug and analysis environment makes ModelSim thesimulator of choice for both ASIC and FPGAdesign.
ModelSim PE (Personal Edition)is the industry-leading, Windows-based simulator for VHDL, Verilog,or mixed-language simulation environments offering a very costeffective solution for RTL and gate levelsimulation;
ModelSim DE (Deluxe Edition)includes full PE functionality plus PSL & SystemVerilog assertions, Code Coverage,
ModelSim SE (System Edition)combines high performance and high capacity with the code coverageand debugging capabilities required to simulate larger blocks andsystems and attain ASIC gate-level sign-off. ModelSim SE offers theability to simulate very large designs.
一些配套的工具
WaveformCompare
The Waveform Compare featurecompares the results of two simulations in order to identify designerrors. Waveform Compare is completely configurable offeringcontinuous compares, clocked compares, and even create
complexcompares using ModelSim's virtual signal capabilities. WaveformCompare results can be viewed in a display window or captured intext files.
Included with ModelSim SE& DE. Cost option forPE.
CodeCoverage
ModelSim code coverageanalysis offers an easy-to-use, integrated code coverage capabilitythat helps develop more complete, robust testbenches quickly.Coverage types supported include statement coverage, branchcoverage,
condition coverage, branch coverage &finite state machine coverage.
Included with ModelSim SE& DE. Cost option for PE.
Xilinx SecureIP interface(Replaces SWIFT Interface)
The ModelSim SecureIP optionallows simulation of Xilinx encrypted IP cores. The SecureIPinterface offers vastly greater simulation performance over theinstantiation of these cores as gate level netlists.
Included with ModelSim SE& DE. Cost option for PE.
Free upgrade to SecureIP forcustomers with the older SWIFT interface module undermaintenance
ModelSim分几种不同的版本:SE、PE、LE和OEM,其中SE是最高级的版本。而集成在 Actel、Atmel、Altera、Xilinx以及Lattice等FPGA厂商设计工具中的均是其OEM版本。
MODELSIM SE是主要版本号,也是功能最强大的版本,支持对Verilog和VHDL语言的混合仿真。除了主要版本外,Mentor公司还为各大FPGA厂商提供 OEM版本: XE是为Xilinx公司提供的OEM版,包括Xilinx公司的库文件;AE是为Altera公司提供的OEM版,包含Altera公司的库文件;在用特定公司的OEM版进行仿真时不需要编译该公司的库文件,但是仿真速度等性能指标都要落后于SE的版本。
SE版和OEM版在功能和性能方面有较大差别,比如对于大家都关心的仿真速度问题,以Xilinx公司提供的OEM版本ModelSim XE为例,对于代码少于40000行的设计,ModelSim SE 比ModelSim XE要快10倍;对于代码超过40000行的设计,ModelSim SE要比ModelSim XE快近40倍。以下列表介绍了OEM版本(以Xilinx公司提供的ModelSim XE版本为例)与ModelSim SE版本之间的差异。
ModelSim SE支持PC、UNIX和LINUX混合平台;提供全面完善以及高性能的验证功能;全面支持业界广泛的标准;Mentor Graphics公司提供业界最好的技术支持与服务。
