Abstract
A method of configuring an FPGA lookup table to implement both exact and relative matching comparators is disclosed. Examples of exact matching of two variables, exact matching of a variable to a constant, relative matching (greater than) of a variable to a constant, and combined exact and relative matching are discussed. Use of the comparator to trigger a logic analyzer to collect data is discussed.
