Generate Custom Bitstream

Create a dlhdl.ProcessorConfig object.

hPC = dlhdl.ProcessorConfig;

Setup the tool path to your design tool. For example, to setup the path to the Vivado^® design tool, enter:

hdlsetuptoolpath('ToolName', 'Xilinx Vivado', 'ToolPath', 'C:\Xilinx\Vivado\2019.2\bin\vivado.bat');

Generate the custom bitstream.

dlhdl.buildProcessor(hPC);

After the bitstream generation is completed, you can locate the bitstream file at cwd\dlhdl_prj\vivado_ip_prj\vivado_prj.runs\impl_1, where cwd is your current working directory. The name of the bitstream file is system_top_wrapper.bit. The associated system_top_wrapper.mat file is located in the top level of the cwd.

To use the generated bitstream for the supported Xilinx^® boards, you should copy the system_top_wrapper.bit and system_top_wrapper.mat files to the same folder.

To use the generated bitstream for the supported Intel^® boards, you should copy the system_core.rbf, system.mat, system_periph.rbf, and system.sof files to the same folder.

Deploy the custom bitstream and deep learning network to your target device.

hTarget = dlhdl.Target('Xilinx');
snet = alexnet;
hW = dlhdl.Workflow('Network',snet,'Bitstream','system_top_wrapper.bit','Target',hTarget);
% If your custom bitstream files are in a different folder, use:
% hW = dlhdl.Workflow('Network',snet,'Bitstream',...
'C:\yourfolder\system_top_wrapper.bit','Target',hTarget);
hW.compile;
hW.deploy;
