SAN JOSE, Calif., Jan. 14, 2014 /PRNewswire/ --Cadence Design Systems, Inc.
(NASDAQ: CDNS), a leader in global electronic design innovation, today
announced that Renesas Electronics Corporation shortened its design and
verification time by 70 percent by utilizing Cadence® C-to-Silicon Compiler to
develop High Efficiency Video Coding (HEVC) intellectual property (IP),
targeting consumer 4K video devices. This enabled the company to quickly offer
their customers IP supporting this next-generation video codec.

Renesas established its own coding style and reduced code size by almost half
with SystemC to create the HEVC IP at a high level of abstraction. This
enabled verification times that were six times faster than register-transfer
level (RTL). This approach also enabled Renesas to use C-to-Silicon Compiler
to explore many algorithmic implementations to generate high-performance RTL
while minimizing power consumption and chip area. To eliminate any potential
schedule impact from a significant engineering change order (ECO) late in the
project, Renesas developed an ECO flow utilizing C-to-Silicon Compiler with
Encounter^® Conformal^® ECO Designer. This allowed them to use high-level
synthesis to quickly apply and verify a patch to stay on schedule.

"The challenge with developing this HEVC/H.265-compliant IP was to incorporate
our proprietary new algorithm, which enables high quality and high compression
efficiently," said Toyokazu Hori, department manager of Platform Base
Technology Development Department, Automotive Information System Business
Division at Renesas Electronics Corporation. "Deploying the system-level
design approach with C-to-Silicon Compiler for the entire design addressed
this challenge and we were able to implement the new algorithm very
efficiently, achieving a good time-to-market for our advanced new IP."
