CAD Based Standard ECL FASTBUS Interface

We have designed, built and tested 7 different Fastbus boards for the Collider Detector Facility (CDF) trigger system. Each of the boards has by necessity had a somewhat different Fastbus interface; two have block transfer and the number of registers per board varies. In order to facilitate design we have attempted to make schematics in 'building blocks' so that submits of the interfaces are standard, and interfaces for new boards can be built up from existing schematics. The schematics are on a Telesis CAD machine.
