eSilicon Enables Mistletoe Technologies Security System on a Chip

SUNNYVALE & CUPERTINO, Calif. -- November 13, 2006 -- eSilicon Corporation, a leading supplier of custom integrated circuits (ICs), today announced it worked closely with Mistletoe Technologies, Inc. to successfully design and manufacture Mistletoe’s fully integrated VPN-firewall system-on-a-chip (SoC). To achieve its industry-leading multi-Gigabit performance, the SoC required the tight integration of various high-performance security engines, a variety of optimized embedded memories and multiple high-speed external interfaces. The Mistletoe SoC has been selected by several Tier 1 manufacturers for their next generation of VPN / Firewall appliances.

eSilicon provided Mistletoe with a full range of ASIC implementation expertise and support, including IP integration, physical design, Design-for-Test (DFT), IO and packaging design and assembly, and testing and qualification/characterization services for initial silicon prototypes and volume production.

“The Mistletoe SoC design was extremely challenging from a design perspective, as it incorporated several processing elements with tightly coupled memories, including high-speed external memory interfaces,” said Hao Nham, vice president and general manager of design services for eSilicon. “eSilicon and Mistletoe worked closely together on an optimal floorplan and layout, as well as proper IO design, to achieve their target performance requirements.”

“eSilicon enabled us to achieve first-pass success on our security SoC product,” added Kevin Rowett, Chief Technology Officer for Mistletoe Technologies. “Their attention to detail and exemplary system design enabled us to bring to market a highly reliable, high-performance security SoC.”

The companies also achieved first-pass success of the advanced flip-chip package. This was done by using an integrated approach for the package design and analysis, including custom design and layout of the high-speed memories, a redistribution layer (RDL) design, bump placement and substrate routing, and comprehensive noise modeling and analysis.
