Automation of Design for Uncommitted Logic Array

This paper explains the design automation strategy developed at the Ferranti Electronics C.A.D. Centre for the Uncommitted Logic Array (U.L.A.). This strategy was to develop a modular automated design system for the single layer metallisation U.L.A.'s which automatically referred a central design document - the logic diagram. The system handles the function of auto layout and checking. It also links into the logic analysis and test schedule verification system.
