Widex employs Mentor's analog/mixed-signal simulators to design its wireless chips

Hearing aid chip expert Widex has employed Mentor's analog and mixed-signal simulator tools (Eldo, Eldo RF, Questa ADMS and ADiT) to verify and produce its wireless chips made for hearing aids.

These chips with gate count of 500K integrate Digital Signal Processor, memory, and analog/digital converters. With both RF analog and digital all in one chip, mixed-signal and RF verification is key task.

"Our investment in a new methodology encompassing full mixed-signal and RF verification using the Mentor simulation suite paid off immediately," said Morten Kroman, Vice President Research and Development at Widex. "For the first time we were able to completely verify this next-generation wireless chip prior to manufacturing."
