The design of a gate array chip and process suitable for carrying out integrated circuit design exercises at an undergraduate level is described. The array uses simplicity in both processes and design in order to make these exercises economically feasible. The educational value in the exercise is in introducing the students to process design rules and their interpretation. Also it will teach, in a practical manner, the advantages and disadvantages of a gate array implementation for a given logic system. Integrated injection logic is chosen as the technology because of its simplicity and its inherent suitability for realising gate arrays. The novel features of this process are described. The chip architecture is also described in relation to the constraints on in-house design and processing. It is designed as a multiproject chip, where each project has available ten edge-triggered D-types, 54 three output gate and 20 user pads. A typical design example is given together with the projected timescales for the exercise.
