Mentor Graphics ModelSim SE-64_6.5f for Linux i386/x86_64

The ModelSim vopt usage mode achieves industry-leading performance and capacity through very aggressive, global compile and simulation optimization algorithms of Verilog and VHDL, improving Verilog and mixed VHDL/Verilog RTL simulation performance by up to 10X. The performance mode can also improve Verilog gate-level performance by up to 4X and capacity by over 2X. ModelSim also supports very fast time-to-next simulation and effective library management while maintaining high performance with its new black box use model, known as bbox. With bbox, non-changing elements can be compiled and optimized once and reused when running a modified version of the testbench. bbox delivers dramatic throughput improvements of up to 3X when running a large suite of testcases.
