PHYSICAL MODELLING DEVICE FOR USE WITH COMPUTER-AIDED DESIGN

摘要

A device for the modelling of physical components as part (25) of a logic simulation includes a logic simulation computer (17) for implementing an event driven algorithm which is used in conjunction with a static card (23) and a dynamic card (24). Both cards include channels for driving the components as well as detecting the output of the components. Data vectors from the computer are driven through the part and its output is sensed. The dynamic card includes a memory for storing the data vectors and presenting them in a continuous stream to parts which must be operated at a minimum speed, and presenting them in a continuing cycle to parts which are uninitializable.
