codegen

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

Syntax

codegen -config hdlcfg matlab_design_name

codegen -config hdlcfg -float2fixed fixptcfg matlab_design_name

Description

codegen -config hdlcfg matlab_design_name generates HDL or HLS code from MATLAB^® code.

codegen -config hdlcfg -float2fixed fixptcfg matlab_design_name converts floating-point MATLAB code to fixed-point code, then generates HDL or HLS code.

Examples

Generate Verilog Code from MATLAB Code

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

Generate HDL Code from Floating-Point MATLAB Code

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 is mlhdlc_dti.

codegen -float2fixed fixptcfg -config hdlcfg mlhdlc_dti

Input Arguments

hdlcfg — HDL code generation configuration

coder.HdlConfig

HDL code generation configuration options, specified as a coder.HdlConfig object.

Create a coder.HdlConfig object using the HDL coder.config function.

matlab_design_name — MATLAB design function name

character vector

Name of top-level MATLAB function for which you want to generate HDL code.

fixptcfg — Floating-point to fixed-point conversion configuration

coder.FixptConfig

Floating-point to fixed-point conversion configuration options, specified as a coder.FixptConfig object.

Use fixptcfg when generating HDL code from floating-point MATLAB code. Create a coder.FixptConfig object using the HDL coder.config function.
