Summary on Grant Application Form
To develop new concepts and extend existing integrated design automation methods to analogue system level design. This entails: (i) generating novel methods of qualitative reasoning for verification of analogue systems once designed;(ii) developing a methodology for hierarchical system level automation generation;(iii) novel mapping techniques for system level specifications to behavioural models in a design automation environment.Progress:The project is in its 16th month. In the first year a broad knowledge base of analogue integrated design has been accumulated. The emphasis has been on mixed-mode design blocks and as a result a novel design methodology for very low supply voltage, high speed operational amplifiers has been invented. Qualitative reasoning for design correction has been demonstrated by applying existing Q.R. automation software developed underIED/ 1/2190. Over the past 4 months application of Q.R. methodology to system level synthesis has been considered. Appropriate analogue filter architectures are being selected for demonstration. Effects of filter performance on low level building block design have been characterised. Currently behavioural model simulation is being considered to adapt the current level design automation of IED/1/2190 to a system level framework. Thus far there has been a strong emphasis placed upon a more robust, systematic analogue design style which will lend itself to a more modular and computational efficient Q.R. for automated system level correction. The research has so far culminated in 2 international publications related to novel, low power supply operational amplifier design methods. The next phase of the project is to demonstrate the application of Qualitative Reasoning as a means of correcting a behavioural model representation of a continuous-time filter to satisfy a given performance specification.
