Engineering for systems using large scale integration

Our experience in designing and producing over 100 different MOS large scale arrays (LSA's) for a variety of systems and customers has led to a number of changes in our pattern of engineering operations. We have found that the major increase in device complexity called for in LSA's requires extensive use of design aids for acceptable development schedules and costs. In turn, the generation and use of these design aids tie device designers and the logic/system designer closely together.
