Questa Verification Solution

Unified verification from simulation to emulation

Questa verification solution

The Questa verification solution from Siemens EDA, a part of Siemens Digital Industries Software, continues to evolve in response to the growing complexity of SoC designs. Besides the sheer size of designs, the inclusion of multiple embedded processors and advanced interconnect systems, increasing software content and the configurability required by multi-platform based designs require a functional verification solution that unifies a broad arsenal of verification solutions.

Questa verification: plan, allocate and manage

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.

Software has become a major component of SoC system functionality, creating new requirements for block-to system verification reuse and the need for system verification and debug. While software testing of SoC integration and basic functionality as well as the verification of low level driver software can be accomplished in simulation, long, complex sequences that exercise system functionality demand acceleration with full debug visibility. To avoid wasting cycles at the system level, it is critical to identify bugs as early as possible in the process.

Questa lets you apply CDC verification, formal verification, mixed-signal verification, portable stimulus, and other powerful technologies to maximize the effectiveness of your verification at the block- and subsystem-level so your system-level verification can focus on system-level functionality, including software, without having to worry about lower-level bugs taking away from your productivity. No one wants to compromise product quality. However, time-to market pressures dominate SoC projects. To deliver quality within schedule requires improving the time to achieve coverage and quality goals and improving debug productivity.
