A smalltalk/V VLSI CAD application

The purpose of the work described was to explore the utility of the Smalltalk/V object-oriented language in prototyping an application that would form just one module of a potentially much more extensive and complex system, a complete VLSI design system. The author also wanted to investigate issues arising from the fact that the application itself and the development methodology would have to anticipate the integration of a series of processes that would extend both up- and downstream; for example, logical and functional design stages, circuit synthesis and testing etc. Others have applied OOP to logic circuit design and to logic simulation. Here OOP is applied to the physical layout of the mask-level geometrical entities that go to make up the silicon realisation of an IC design
