Questa automates verification and debug of complex SoCs and FPGAs, dramatically increasing productivity and helping companies manage resources more efficiently. Questa best-in-class technologies maximise the effectiveness of verification at the block, subsystem, and system levels.
The Questa Verification Solution
The Questa verification solution is an assemblage of technologies, methodologies, and libraries for modern ASIC and FPGA designs. Questa continues to evolve in response to the growing complexity of SoC designs.
The key to verification success is to decompose the problem and use the best solution for each aspect of the system. This places tremendous importance on the verification plan and the ability to collect metrics throughout the process and across all verification tasks to track progress against the plan, allocate and manage resources efficiently, and identify trends as the project progresses against schedule.
