Abstract :
This paper reports on evaluation of field programmable gate array (FPGA) technology applied to the implementation and testing of VXIbus interface circuitry. Using FPGAs, all the logic of a general purpose breadboard (Hewlett-Packard E1399A) can be fit into a single low-cost gate array package (Xilinx XC4000) with attendant savings in board space. Functions implemented using the FPGA include: (1) data transfer acknowledge (DTACK) state machine; (2) interrupt knowledge state machine, and (3) general interface logic including registers. This results in a reliable, flexible, and testable design that provides the interface between the VXIbus and the user´s custom circuitry
