Objectives and Approach

The integration of analogue and digital functions on a single chip is necessary for the development of new information technologies for data communications, industrial applications and consumer products.

The primary objective of ADCIS was the adaptation and characterisation of a 1 micron CMOS process for mixed analogue-digital functions and the extraction of the electrical parameters of a submicron CMOS technology, together with the definition of submicron rules. At the same time, design tools were to be developed with the goal of building a system capable of being used to produce silicon compilers involving digital and analogue cells. Finally, a complex integrated circuit was to be designed and manufactured to demonstrate the capabilities of the developed technology and CAD tools.

Progress and Results

The most important results achieved by ADCIS were:

• Development of 1 micron CMOS analogue modules, integration into an analogue digital process technology, and full characterisation.
• Fabrication of a submicron test circuit and first characterisation of the 0.7 micron technology.
• Mixed analogue/digital building blocks design, fabrication and characterisation. Blocks coming from different partners and designed with the same rules have been integrated.
• Usage and evaluation of the new CAD tools in the design of blocks, test circuits and demonstrator. During the project various CAD tools have been developed. In mixed signal simulation, several functions (hierarchical modelling, structural models, analogue functional modelling, analogue behavioural language with interface to C and path to VHDL) have been added to the FIDELDO simulator. In mixed signal layout, channel router, global router and block placement have been developed. Finally, several compilers have been produced (successive approximation, high resolution ADC/DAC, module generators, delta sigma and pipelined ADC converters). The tools have been integrated with each other and with some selected cell databases, and user requirements added.
• Design, fabrication and test of a complex IC in 1 micron CMOS technology. The circuit selected was a video processor for telecommunication (videophone) applications and multimedia terminals. The function of the circuit is image acquisition and processing before coding and transmission. It consists of analogue (three analogue/digital converters to produce the red, green, blue signals) and digital (filters for luminance and chrominance matrix) parts.

Exploitation

The 1 micron analogue digital technology developed in this project is currently in the pre-production phase at an industrial partner line and the demonstrator IC is being used as a vehicle for qualification and is already included in the product catalogue. Additional products for telecommunication applications based on this technology are planned to be incorporated. The CAD tools produced in ADCIS will be commercially exploited by an industrial partner.
