Design environment supports 25, 50 & 100G Ethernet

The huge surge in demand for connectivity has had a profound effect on the size of switch and router designs, making them among the largest IC designs developed today. The sheer size of the designs, the pressure for early release and the need to verify all paths are creating a methodology shift that moves verification from simulation- to emulation-based flows.

“Providing a highly scalable, high-density network foundation for our customers’ demanding environments is a top priority as we design Juniper Networks’ advanced switches and routers,” said Debashis Basu, Senior Vice President, Silicon and Systems Engineering, Juniper Networks. “The cutting-edge features in our ASICs make Veloce VirtuaLAB Ethernet and emulation capabilities a key component for achieving verification convergence, helping ensure that we deliver versatile, high-performance switching and routing technology to keep pace with evolving network requirements.”

VirtuaLAB Ethernet transforms emulation for networking chips by replacing the traditional physical devices used in in-circuit emulation with virtual devices. This virtualisation moves emulation from the engineering lab to the computing datacenter for maximum emulation resource utilisation.

VirtuaLAB components provide a complete software-driven Ethernet stack that runs at up to 15,000 times the speed of traditional simulation. This lets VirtuaLAB Ethernet users tackle the complex challenges of Ethernet-based designs with improved throughput, advanced debug, power analysis and performance analysis.

“The rapid development and deployment of high-end Ethernet products for the networking market requires access to high quality IP and complete verification solutions,” said Daniel Kohler, CTO, MoreThanIP. “We have collaborated with Mentor over several years to enable the deployment of robust, fully featured Ethernet verification encapsulated in the Ethernet VirtuaLAB product. Most recently we have collaborated to enable forward error correction verification for high-speed 25, 50 & 100G designs.”

The accelerated deployment of VirtuaLAB solutions in the networking market is the result of significant and repeatable improvements in throughput. For example, in simulation it’s not uncommon to run 1,000 packets of data per day. When compared to emulation, the difference is staggering. Here customers report they are running 11,000,000 packets of data per day.

“We collaborate with leading-edge networking companies to provide solutions that address their verification challenges. The rapid growth of these designs and the need to verify every path creates a huge verification space resulting in a major shift from simulation to emulation,” said Eric Selosse, Vice President and General Manager, Mentor Emulation Division. “We developed VirtuaLAB Ethernet and other solutions that transform emulation, enabling our Veloce customers to meet their complex verification goals.”
