Generate HDL or High-Level Synthesis (HLS) code from MATLAB code

Syntax

Description

codegen -config [hdlcfg](#btqy2qf-hdlcfg) [matlab_design_name](#btqy2qf-matlab%5Fdesign%5Fname) generates HDL or HLS code from MATLAB® code.

example

codegen -config [hdlcfg](#btqy2qf-hdlcfg) -float2fixed [fixptcfg](#btqy2qf-fixptcfg) [matlab_design_name](#btqy2qf-matlab%5Fdesign%5Fname) converts floating-point MATLAB code to fixed-point code, then generates HDL or HLS code.

example

Examples

Create a coder.HdlConfig object, hdlcfg.

hdlcfg = coder.config('hdl'); % Create a default 'hdl' config

Set the test bench name. In this example, the test bench function name is mlhdlc_dti_tb.

hdlcfg.TestBenchName = 'mlhdlc_dti_tb';

Set the target language to Verilog®.

hdlcfg.TargetLanguage = 'Verilog';

Generate HDL code from your MATLAB design. In this example, the MATLAB design function name is mlhdlc_dti.

codegen -config hdlcfg mlhdlc_dti

Create a coder.FixptConfig object, fixptcfg, with default settings.

fixptcfg = coder.config('fixpt');

Set the test bench name. In this example, the test bench function name is mlhdlc_dti_tb.

fixptcfg.TestBenchName = 'mlhdlc_dti_tb';

Create a coder.HdlConfig object, hdlcfg, with default settings.

hdlcfg = coder.config('hdl');

Convert your floating-point MATLAB design to fixed-point, and generate HDL or HLS code. In this example, the MATLAB design function name ismlhdlc_dti.

codegen -float2fixed fixptcfg -config hdlcfg mlhdlc_dti

Input Arguments
