OKI Network LSI Reduces Test Time 90% by Combining the Open Verification Methodology (OVM) and Cadence Incisive Technologies

-- Cadence Design Systems, Inc. (NASDAQ: CDNS), the leader in global electronic design innovation, today announced that OKI Network LSI Co., Ltd., is reporting significant benefits from its use of the Open Verification Methodology (OVM) with Cadence Incisive functional verification technology. Co-developed by Cadence and released last year, the OVM is the first scalable, open, multi-vendor verification methodology for SystemVerilog in the industry.

OKI Network LSI reported numerous benefits from using the OVM, chief among them the ability to use sequences for controlling test scenarios and testbench development. Combining the Incisive coverage-ranking capability with the OVM, OKI Network LSI was able to optimize the test scenarios for simulation, which provided a 90 percent reduction in regression test time. With the OVM, OKI Network LSI believes it can build a highly reusable testbench that would deliver a 50 percent overall project time savings.

OKI Network LSI provides third-party verification services for huge SoCs that contain advanced on-chip buses such as AXI and OCP, and the company believes that advanced verification technology such as the OVM is essential.

"Our clients need a verification solution that can scale for sophisticated System on Chip (SoC) applications," said Takahiro Kobori, senior general manager, LSI Design and Development Division. "The scalable, open, interoperable nature of the OVM makes it ideal for our clients and we found the transition to it has been quite smooth. In particular, the configuration was easy, and the built-in architecture for verification components enabled us to quickly create highly reusable verification IP."

"OKI Network LSI is one of many companies recognizing the benefits of the Open Verification Methodology," said Michal Siwinski, Enterprise Verification group marketing director at Cadence. "The company has discovered that transitioning to the OVM can be a very smooth process that pays dividends quickly."
