Questa Advanced Simulator Questa's core simulation and debug engine 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. Advanced Debug with Questa Advanced Debug with Questa On-demand Web Seminar View Video 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. Features High Performance and Capacity Assertion Based Verification Test Automation Questa Verification Management Integrated Multi-Language Debugging Power Aware Verification High Performance and Capacity The Questa Advanced Simulator achieves industry-leading performance and capacity through very aggressive, global compile and simulation optimization algorithms of SystemVerilog and VHDL, improving SystemVerilog and mixed VHDL/SystemVerilog RTL simulation performance by up to 10X. Questa also supports very fast time-to-next simulation and effective library management while maintaining high performance with unique capabilities to pre-optimize and define debug visibility on a block by block basis enabling dramatic regression throughput improvements of up to 3X when running a large suite of tests. To increase simulation performance for large designs with long simulation times, Questa also has a Multi-Core option. Questa Multi-Core takes advantage of modern compute systems by partitioning the design to run in parallel on multiple CPU’s or computers using either automatic or manually driven partitions. To achieve even greater performance, Questa supports TBX; the highest performance Transaction Level link to the Veloce platform enabling a 100x increase in performance with debug visibility and a common testbench.
