Mentor Graphics Helps eoSemi Solve the Challenge of Silicon Oscillator Design

eoSemi and Mentor Graphics (NASDAQ:MENT) today announced that
the Pyxis™ Custom Design environment, Eldo® simulator and Calibre®
tools have been used in the design and verification of eoSemi’s
recently-announced ATOC™ (Accurate Timing Oscillator Circuit)
silicon oscillator products.
ATOC (Accurate Timing Oscillator Circuit) oscillators are
all-CMOS silicon replacements for quartz crystals. By saving space,
increasing reliability and reducing costs, they allow designers to
build consumer electronic products that are more compact, offer
more features and deliver superior battery life. In addition,
because they are manufactured with standard semiconductor
processing technologies, they can in the future be integrated
quickly and easily within a larger device or a printed circuit
substrate.
“Mentor has supported us from the outset via its Terms for
Start-Ups program and its involvement with the European
Microelectronics Academy,” said Adrian Bratt, eoSemi’s vice
president of engineering. “Access to world-class design tools is
vital for a business taking its first steps, particularly in a
specialist area such as analog and mixed-signal design. Our
relationship with Mentor has been instrumental in bringing the
first wave of ATOC products from engineering to
productization.”
eoSemi used the Pyxis Custom Design environment, the Eldo SPICE
accurate circuit simulator and the Calibre LVS/DRC (layout versus
schematic and design rule checking) tools in the design of its
first ATOC products, which are currently sampling to qualified
customers. The company delivered ATOC significantly ahead of plan,
and industry analysts have commented on the speed with which the
eoSemi team has developed its products.
“Engineering an all-silicon oscillator is one of the big
challenges for mixed-signal designers in standard CMOS,” said
Robert Hum, vice president and general manager of the Deep
Submicron Design at Mentor Graphics. “In fact, semiconductor and
system houses have wrestled with the problem for years, without
success. We’re proud that eoSemi has been able to use the
flexibility of the Pyxis Custom Design environment, the speed and
accuracy of the Eldo simulator—coupled with fast, hierarchical
verification via Calibre—to finally solve such a tough
problem.”
ATOC includes proprietary techniques to sense and compensate for
the effects of temperature and physical stress within the device.
The oscillator’s output frequency can be tuned both instantaneously
in real-time, and over the lifetime of the device. The first ATOC
product is aimed at the $800M market for 32kHz timing references in
consumer products. It draws just 8µA of supply current in active
mode, and delivers accuracy down to ±30ppm with an operating
temperature range of -40 to +85°C.
