Namespace: dlhdl

Retrieve bitstream resource utilization

Since R2021a



area = getBuildInfo(workflowObject) returns a structure containing the bitstream resource utilization.

Input Arguments

expand all

Deep learning network deployment options, specified as a dlhdl.Workflow object.

Output Arguments

expand all

Bitstream resource utilization returned as a structure.

  • The Block Memory Bits utilization is available for Intel® bitstreams only.

  • The resource utilization results of Intel bitstreams show the Block RAM utilization as 100%. To analyze bitstream resource utilization, refer to the Block Memory Bits utilization instead.

  1. Create a file in your current working folder called getLogoNetwork.m. In the file, enter:

    function net = getLogoNetwork
     if ~isfile('LogoNet.mat')
            url = '';
        data = load('LogoNet.mat');
        net  = data.convnet;
  2. Create a dlhdl.Workflow object that has LogoNet as the Network argument and arria10soc_single as the Bitstream argument.

    snet = getLogoNetwork;
    hW = dlhdl.Workflow('Network',snet,'Bitstream','arria10soc_single');
  3. Call getBuildInfo argument to retrieve the arria10soc_single resource utilization. Store the resource utilization in area.

    area = hW.getBuildInfo
