Siemens Digital Industries Software Mentor’s Questa verification solution helps Leonardo accelerate aerospace FPGA development
Mentor, a Siemens business, announced today that Leonardo has accelerated its field programmable gate array (FPGA) design cycle, using advanced verification techniques made possible with the Questa™ verification solution.
Leonardo is among the top ten global players in Aerospace, Defense and Security. Mentor’s Questa provides a comprehensive, best-in-industry verification solution for integrated circuit (IC) design and verification.
Leonardo has been using Mentor’s Questa SystemVerilog verification solution, applying the Universal Verification Methodology (UVM) framework and Questa Verification IP (QVIP) to the design, verification and validation (V&V) of highly complex avionics interfaces. Results achieved to date indicate an acceleration of the design, V&V and system integration phases of a key product.
Incorporation of the UVM framework, QVIP and Verification Run Manager into a Jenkins software-based environment has extracted further value from the toolkit, enabling automated reverification of designs, post modification.
Electronically scanned array radar systems contain a multitude of central processing units (CPUs) and FPGAs, spread across several subsystems, with the FPGAs implementing control, digital signal processing (DSP) and communication functions. “Designing a complex system like this is a daunting task, especially when you take into account the tight schedule demanded by today’s fast-paced marketplace,” said Iain Wildgoose, vice president of Engineering, Radar and Advanced Targeting for Leonardo’s Airborne and Space Systems Division. “The reuse and scalability that the UVM framework and QVIP delivered, combined with the support to the adoption process provided by Mentor consultants and application engineers, were key enablers to successful design and integration.”
Mentor QVIP provides an easy-to-use library of verification IP for more than 40 standard protocols and 1,700 memory devices. QVIP includes checkers and coverage, plus a comprehensive set of stimulus sequences for the protocols. Adoption of QVIP IP for the standard interfaces enabled Leonardo to focus on the unique specifics of the company’s design. QVIP and the UVM framework — a set of base classes layered on top of UVM — have enabled Leonardo to increase code coverage significantly in a short period of time.
With Mentor’s UVM framework, test bench creation time is reduced, as is the interpretation of test bench results, through abstraction of this task to a higher level. Leonardo was able to deploy Questa across projects to accelerate test bench development and efficient coverage closure. After these initial successes, Leonardo is now deploying the UVM framework to other projects across the company.
“Increasingly complex FPGA designs demand reusable and scalable verification solutions that accelerate development and increase overall quality,” said Ravi Subramanian, vice president and general manager, IC Verification Solutions Division at Mentor. “The Questa solution, coupled with the UVM framework and QVIP, reduces testbench and VIP development time by automatically generating project test benches. Our industry-leading application engineers, consultants, and online resources enable easy adoption of these techniques that will pay dividends for many projects to come.”
