Mon. November 02, 2009; Posted: 12:42 AM

Nov 01, 2009 (Close-Up Media via COMTEX) -- MENT | Quote | Chart | News | PowerRating -- Mentor Graphics announced that Widex, a developer of digital hearing aid technology, has used the entire set of analog and mixed-signal simulator tools (Eldo, Eldo RF, Questa ADMS and ADiT) to verify and produce its most complex wireless chip to date.

Digital hearing aid systems are complex battery-operated systems, including DSP, memory, and analog/digital converters. In the recently announced series from Widex, they have introduced a new family of products with wireless functions.

The wireless chip set includes about 500K digital gates using multiple power supply domains, where the interaction with analog and RF blocks is extremely complex, particularly during the booting sequence of the chip. Widex's primary motivation for adopting a mixed-signal verification methodology using Mentor tools was to ensure all mixed-signal interconnections were accurately verified through simulation.

All research, development and administration, as well as most of the production, takes place at Widex headquarters in Vaerlose, Denmark. Furthermore, the company has assembly facilities in Helsinge in Northern Zealand and in Verviers in Belgium.

Mentor Graphics is a developer of electronic hardware and software design solutions, providing products, consulting services and support for electronics and semiconductor companies.
