%  Purpose : MRI DDC top level script
%

%% MRI DDC Model

% Run a MATALB filter model in order to build all the required filters
% using MATLAB functions
clear
mri_model
close all;

%% MRI DDC netlist generation

% Create a netlist by running mri_filter_netlist.m script. The output is a
% .mdl Sysgen netlist

params = {};
block=xBlock('mri_filter_netlist', params)

%% Hardware settings

% Set all the chip-specific parameters in the top level of the Sysgen
% netlsit.

blockHandle = block.getHandle;
sysgenToken = xlFindMasterAbove(blockHandle);
xlsetparam(sysgenToken, 'sysclk_period', sprintf('%d', 1e9/fadc));
xlsetparam(sysgenToken, 'xilinxfamily', 'Virtex5');
xlsetparam(sysgenToken, 'part', 'xc5vsx35t');
xlsetparam(sysgenToken, 'speed', '-1');
xlsetparam(sysgenToken, 'package', 'ff665');

%% Save the model

% Save the model as mri.mdl file. Now it's ready to be simulated either
% through GUI or just by running run('mri') command in a script.

mdlHandle = bdroot(blockHandle);
set_param(mdlHandle, 'StopTime', sprintf('%d', length(sample)*2+step_delay+10));
close_system(mdlHandle, 'mri');
