Cedar Point Communications has used the native testbench technology in the VCS comprehensive RTL verification solution to simplify testing and speed time to market for its Safari C(3) VoIP switch.

Cedar Point Communications, the leader in integrated packet-based voice switching technologies for the cable industry, has used the native testbench (NTB) technology in Synopsys' VCS comprehensive RTL verification solution to simplify testing and speed time to market for its Safari C(3) VoIP switch.

The Safari C(3) multimedia switching system is the only totally integrated carrier class switch that incorporates - at no additional cost - all of the components that make up the PacketCable voice switching infrastructure.

The VCS solution is a key component of the Synopsys Discovery Verification Platform.

"Our advanced field programmable gate array (FPGA) designs require sophisticated verification tools and techniques to help ensure optimum performance for our customers", said Kostas Kalaitzidis, Lead FPGA Verification Engineer at Cedar Point.

"Synopsys' VCS NTB technology allowed us to easily write testbench drivers and monitors for a wide variety of complex packet-based protocols and to develop directed and randomised tests that reflect cable operators' field needs".

VCS NTB technology with support for the SystemVerilog and OpenVera languages deploys a unique, single-compiler architecture to simultaneously optimise design, testbench, assertions and coverage, delivering up to five times faster verification performance compared with independent testbench and simulation environments.

VCS NTB supports advanced testbench capabilities such as constrained-random stimulus generation, object-oriented programming, advanced data types and more.

The VCS solution's built-in code and functional coverage engines help ensure more predictable verification closure by enabling engineers to accurately monitor verification progress over time, and to determine when verification is complete.

"Synopsys' VCS NTB technology is unique in the industry", said Farhad Hayat, Vice President of Marketing, Verification Group, Synopsys.

"It brings advanced verification methods, including coverage, assertions and testbench automation, directly into the simulator to yield a fast, comprehensive verification solution".

"Our customers are routinely seeing speedups of up to five times when they use VCS NTB".
