function map = output_map(N)

% output_map generates the output data mapping from each coarse uBF such
% that the data stream can be mapped to the correct coarse uBF within the
% array
% INPUTS:
% N - number of elements in ASIC
% OUTPUTs:
% map - map from ASIC output channels to corresponding coarse uBF

map = zeros(sqrt(N),sqrt(N));
