getBuildInfo

Class: dlhdl.Workflow
Namespace: dlhdl

Retrieve bitstream resource utilization

Since R2021a

Syntax

area = getBuildInfo(workflowObject)

Description

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

Input Arguments

workflowObject — Deep learning network deployment options

dlhdl.Workflow object

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

Output Arguments

area — Bitstream resource utilization

structure

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

1. 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

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
