IC Verification

IC verification can account for up to seventy percent of the IC design cycle. Leading verification teams not only have to ensure their designs are functionally correct, they must also validate and test their ICs in the context of the entire end-system.

Advanced Verification

Large, complex System-on-Chips (SoCs) require boosting verification productivity and managing resources more efficiently. Delivering product quality within tight schedules requires maximising verification effectiveness to speed time to coverage closure, hit quality goals and improve debug productivity.

The inclusion of multiple embedded processors and advanced interconnect systems, increasing software content, more functionality, and the configurability required by multi-platform based designs all require a functional verification solution that unifies a broad arsenal of verification solutions.

The Questa verification solution transforms verification, dramatically increasing verification productivity and managing resources more efficiently. Built on several powerful technologies, Questa continues to evolve in response to the growing complexity of SoC designs.

Debug is one of the most important verification technologies and is critical for achieving productivity in today’s complex designs. Companies need debug tools that provide maximum performance, capacity and automation for the complete system-on-chip design and verification cycle.

More complex designs that include more software create new requirements for block-to-system verification reuse and the need for system verification and debug. To avoid wasting cycles at the system level, it is critical to identify bugs as early as possible and improve debug productivity.

Designers of today’s electronics can’t afford to overlook the integrity of their design in any or all aspects including correctness, safety, trust, and security. Companies have an obligation to meet functionality, safety, and security requirements or they are met with swift ramifications. Once that occurs, consumer trust is eroded and difficult to get back. Turning out a product that has unknown performance or power issues, for example, can spell doom when detected in the field.

Meeting these requirements becomes tougher and tougher as innovation progresses, however. This up-shift means that companies have to be hyper-diligent not only about the functional correctness of their designs but also the safety, trust, and security. The design must operate as intended in even the most adverse environmental conditions and be immune to any unwarranted interference. To say it concisely, companies must be fully invested in the entire integrity of their IC – functional correctness, safety, trust, and security.

User-friendly automated formal applications simplify the process of identifying and resolving bugs, eliminating the need for specialized formal expertise.


A significant evolution is underway in SoC verification, especially in the areas of AI, 5G and Automotive. Design complexity has created the need for extensive internal visibility into the design to understand subtle problems that can occur during silicon bring-up. FPGA based prototyping has become an essential tool in today’s SoC and ASIC design and verification.

The Veloce hardware-assisted verification system is the first complete, integrated offering that combines best-in-class virtual platform, hardware emulation, and FPGA prototyping technologies and paves the way to leverage the latest powerful hardware-assisted verification methodologies.

Veloce proFPGA dramatically lowers the adoption barrier of the FPGA desktop prototype solution. Together with the performance that is possible to reach thanks to its architecture innovations, the solution is easy to deploy and engineers can now bring-up on their own lab environment quickly and reliably.
