Sanjay Gupta, senior director of R&D, Mentor Emulation Division, Mentor, presented on the design verification trends and role of emulation.
Verification needs are expanding beyond traditional functional verification. SoC power analysis, coverage closure and DFT validations are critical. Vertical market segment focus is crucial as verification needs are different for different verticals. Verification teams are global teams. Veloce platform addresses the modern verification challenges.
Talking about the design trends, ~31 percent of designs use over 800 million gates and ~20 percent use over 500 million gates.Next, 72 percent of designs contain embedded processors, and 49 percent designs contain two or more processers, while 16 percent designs have eight or more processors.
As for ASIC/IC completion to the original schedule, 61 percent designs were behind schedule in 2014, which increased to 69 percent during 2016. The number of required ASIC/IC spins before production had become seven spins or more in 2016.
Regarding verification trends, as for more design engineers vs. verification engineers, design engineers were growing at CAGR 3.6 percent, while verification engineers were growing at CAGR 10.4 percent, from 2007-2016. The ASIC/IC verification engineers were spending 39 percent of their time at debugging, 22 percent each at creating test and running simulation, and testbench development, and 14 percent time in test planning.
SystemVerilog was a clear leader at the ASIC/IC verification language adoption, while Accelera UVM was a clear leader at the ASIC/IC testbench methodology adoption trends.
In power and coverage, 72 percent more designs wre actively managing power in 2016 as against 59 percent in 2007. Among the power intent trends, the UPF 2x was a clear leader among notations used to describe power intent. Functional coverage is just nearly on par with code coverage, followed by assertions and constrained-random simulation, as far as the ASIC/IC dynamic verification trends are concerned.
Challenges for verification include larger, more complex chips, as well as the increasing software content. Transistor count for select ICs will likely reach 15 billion gates by 2022.
Vertical segments are facing constant innovation. In networking, SDN emergence is driving complexity, size, and port count. There is an increased importance of software. Networking is driven by Big Data, cloud and mobility.
Safety is critical verification for automotive design. Veloce delivers the functional safety verification. Emulation has moved to virtualization with Veloce2. Data-center friendliness and enterprise-level usage are prime. Veloce Strato has accelerated and moved on to the application age, and has a vertical market focus.
Crystal chip is the brain of the Veloce emulation platform. A chip is designed exclusively for emulation: fast compile and efficient, full visibility. The chip, system and software are architected together to optimize the emulation capabilities and productivity. The Veloce Strato offers the lowest cost of ownership.
Veloce power app offers low-power verification at SoC level where power controls come from the application software, handles large SoC (RTL/Gate) with full visibility, performs complete verification (e.g. OS boot) and shows accurate power numbers based on real switching activity.
You can also do low power verification with Veloce. There is broad UPF 2.x support and UPF 3.0 support is planned by the end of 2017. Veloce coverage app has comprehensive SVA assertion support, SV functional coverage, code coverage, standard UCDB support and merged with simulation UCDB, and flow to enable XML merge with other platforms.
