EDA (Circuits) Overview Paul Hasler Extent of Circuits (Analog/Digital) Hearing aids Cell Phones Digital Cameras Automotive MEMs devices / Circuits Biomedical Analog ~ 20% of IC market since 1970 “The Analog Renaissance is Here!” --- Brian Halla CEO National Semiconductor “Analog chips enable computers to interact with the physical world--to see, listen, touch. . .the next ten years will see a shift in emphasis to analog technologies. . . In the coming years, look for analog--not digital--chips to attract the new talent and investment. . .” --- Red Herring Magazine, February 2003 "DSP and high-performance analog are the engines . . . and we're only at the beginning of where analog is going." --- Templeton, incoming CEO of TI, February 2004 Range of Analog Products (Just TI’s map) Brief History of Integrated Circuits (1960) 4004: First mP (1970) Silicon Scaling “Standard” digital CMOS Course Directions in EDA ECE 4420: Digital IC Design ECE 4415: RF Engineering I ECE 4418: RF Engineering II ECE 4430: Analog IC Design ECE 4360: RF Lab ECE 6412: Analog Circuits (IC) ECE 6435: Analog VLSI Circuits ECE 6361: RF Design Lab ECE 6414: Analog Systems (IC) ECE 6420: Wireless IC Design ECE 4430: Analog IC Design Analog--Digital Signal Processing Real world (analog) Gene’s Law and CADSP A/D Converter DSP Processor Computer (digital) 1W ASP IC A/D DSP Processor Computer (digital) Power / MMAC Specialized A/D Real world (analog) 10mW Sensor Signals DSP/mC Programmable Analog Power Savings 0.1mW CADSP = Cooperative Analog—Digital Signal Processing (P.
