Method, apparatus and computer program product for spur detection in a sampled waveform in a mixed analog/digital system using the magnitude of the frequency response comprising acquiring a sample waveform including a set of discrete uniformly spaced samples from a target system, wherein the sample waveform is a time domain vector; applying FFT transforming the time domain vector into the frequency domain; analyzing the frequency domain response including calculating the magnitude response; and determining whether the sample waveform has spurs including comparing the magnitude response to an average noise floor threshold including determining that the magnitude response having an average noise floor value above the average noise floor threshold has one or more spurs and determining that the magnitude response having an average noise floor value below the average noise floor threshold has no spurs, wherein a spur indicates unaligned data having a delayed bit flip.

A method for providing a computer system including: a trivial file transfer protocol (TFTP) server computer, a system management controller computer and a set of subnet(s) including a first subnet, with each subnet of the set of subnet(s) including a primary computer and a plurality of host computers that respectively include a field programmable gate array (FPGA) with programmable blocks, polling, by the system management controller, each computer of the first subnet to determine that all of the computers of the first subnet are ready to receive a broadcast of an FPGA image, instructing the TFTP server computer to send the FPGA image to all of the machines of the first subnet; and sending, by the TFTP server computer and to all of the computers of the first subnet, the FPGA image.
