getBuildInfo

Class: dlhdl.Workflow
Package: dlhdl

Retrieve bitstream resource utilization

Description

example

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

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.

Examples

Retrieve arria10soc_singleBitstream Resource Utilization

Retrieve the resource utilization for the arria10soc_single bitstream.

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

function net = getLogoNetwork
 if ~isfile('LogoNet.mat')
        url = 'https://www.mathworks.com/supportfiles/gpucoder/cnn_models/logo_detection/LogoNet.mat';
        websave('LogoNet.mat',url);
    end
    data = load('LogoNet.mat');
    net  = data.convnet;
end

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');

Call getBuildInfo argument to retrieve the arria10soc_single resource utilization. Store the resource utilization in area.

area = hW.getBuildInfo
