This report describes the development of a multichannel time-interval-measurement unit using a field programmable gate array FPGA. Precise time-interval measurement is required for a number of applications including clock stability analysis, time-of-flight measurements, and particle physics. This research was geared toward pulse-per-second monitoring but can easily be applied to other applications. The FPGA implementation lends itself to a multichannel design and offers a low-cost solution compared to commercial or custom application-specific integrated circuit solutions. The design goal of 10-ns resolution on 10 channels was achieved, with additional proof-of-concept development demonstrating subcycle accuracy.
