Computer generated timing diagrams to supplement simulation

The ISPS computer description language has been used in a simulation study to specify the components of a high speed data acquisition system and its protocols. A facility has been developed for automatically generating timing diagrams from the specification of the data acquisition system written in the ISPS description language. Diagrams can be generated for both normal and abnormal working modes of the system. They are particularly useful for design and debugging in the prototyping stage of a project and can be later used for reference by maintenance engineers. (11 refs).
