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.

Questa spans the levels of abstraction required for complex SoC and FPGA design and verification from TLM (Transaction Level Modeling) through RTL, gates, and transistors and has superior support of multiple verification methodologies including Assertion Based Verification (ABV), the Open Verification Methodology (OVM) and the Universal Verification Methodology (UVM) to increase testbench productivity, automation and reusability.
