VCE Exam Simulator is a test engine designed specifically for certification exam preparation. It allows you to create, edit, and take practice tests in an environment very similar to an actual exam.

NL5 is the Non-Linear Electronic Circuit Simulator. The first version of NL for personal computers was developed in the early �90s as a tool for switching power supplies design. Since then NL has evolved into the Microsoft Windows®-based NL4, which has been used extensively by world-class engineers in different fields of electronics for almost 10 years. NL5 is the first version to be publicly available.

ModelSim is the industry-leading, Windows-based simulator for VHDL, Verilog, or mixed-language simulation environments. Mentor Graphics was the first to combine single kernel simulator (SKS) technology with a unified debug environment for Verilog, VHDL, and SystemC. The combination of industry-leading, native SKS performance with the best integrated debug and analysis environment make ModelSim the simulator of choice for both ASIC and FPGA designs. The best standards and platform support in the industry make it easy to adopt in the majority of process and tool flows.

The Questa Advanced Simulator combines high performance and capacity simulation with unified advanced debug capabilities for the most complete native support of Verilog, SystemVerilog, VHDL, SystemC, PSL and UPF. The Questa Advanced Simulator is the core simulation and debug engine of the Questa Verification Platform; the comprehensive advanced verification platform capable of reducing the risk of validating complex FPGA and SoC designs.
