BDA Analog FastSPICE (AFS) Platform

时间:12-12 整理:3721RD 点击:
The Analog FastSPICE™ (AFS) Platform is the world’s fastest nanometer
circuit verification platform for analog, RF, mixed-signal, and custom
digital circuits. More than 120 companies use the AFS Platform for their
toughest circuit verification challenges, including high-speed I/O, PLLs,
ADCs/DACs, CMOS image sensors, RFICs, and embedded memory.
