function delay_bram_en_plus_init_xblock(blk, DelayLen, bram_latency)
% This is a generated function based on subsystem:
%     more_delays/delay_bram_en_plus
% Though there are limitations about the generated script, 
% the main purpose of this utility is to make learning
% Sysgen Script easier.
% 
% To test it, run the following commands from MATLAB console:
% cfg.source = str2func('delay_bram_en_plus');
% cfg.toplevel = 'more_delays/delay_bram_en_plus';
% args = {my_DelayLen, my_bram_latency};
% xBlock(cfg, args);
% 
% You can edit delay_bram_en_plus.m to debug your script.
% 
% You can also replace the MaskInitialization code with the 
% following commands so the subsystem will be generated 
% according to the values of mask parameters.
% cfg.source = str2func('delay_bram_en_plus');
% cfg.toplevel = gcb;
% args = {DelayLen, bram_latency};
% xBlock(cfg, args);
% 
% To configure the xBlock call in debug mode, in which mode,
% autolayout will be performed every time a block is added,
% run the following commands:
% cfg.source = str2func('delay_bram_en_plus');
% cfg.toplevel = gcb;
% cfg.debug = 1;
% args = {DelayLen, bram_latency};
% xBlock(cfg, args);
% 
% To make the xBlock smart so it won't re-generate the
% subsystem if neither the arguments nor the scripts are
% changes, use as the following:
% cfg.source = str2func('delay_bram_en_plus');
% cfg.toplevel = gcb;
% cfg.depend = {'delay_bram_en_plus'};
% args = {DelayLen, bram_latency};
% xBlock(cfg, args);
% 
% See also xBlock, xInport, xOutport, xSignal, xlsub2script.
