coder.config

R2026b

Create HDL Coder code generation configuration objects

Syntax

hdl_config = coder.config("hdl")

hls_config = coder.config("hls")

fixpt_config = coder.config("fixpt")

Description

hdl_config = coder.config("hdl") creates a coder.HdlConfig configuration object for use with the HDL codegen function when generating HDL code from MATLAB^® code.

hls_config = coder.config("hls") creates a coder.HlsConfig configuration object for use with the codegen function when generating High-Level Synthesis (HLS) code from MATLAB code.

fixpt_config = coder.config("fixpt") creates a coder.FixptConfig configuration object for use with the HDL codegen function when generating HDL code from floating-point MATLAB code. The coder.FixptConfig object configures the floating-point to fixed-point conversion.

Examples

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

Generate HLS Code from MATLAB Code

Create a coder.HlsConfig object, hlscfg, with default settings.

hlscfg = coder.config("hls");

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

hlscfg.TestBenchName = "myDesign_tb";

Generate HLS code from your MATLAB design. In this example, the MATLAB design function name is myDesign.

codegen -config hlscfg myDesign

Output Arguments

hdl_config — HDL code generation configuration object

coder.HdlConfig

HDL code generation configuration object, returned as a coder.HdlConfig object. Use this object with the codegen function to generate HDL code.

hls_config — HLS code generation configuration object

coder.HlsConfig

HLS code generation configuration object, returned as a coder.HlsConfig object. Use this object with the codegen function to generate HLS code.

fixpt_config — Floating-point to fixed-point conversion configuration object

coder.FixptConfig

Floating-point to fixed-point conversion configuration object, returned as a coder.FixptConfig object. Use this object with the codegen function when converting floating-point MATLAB code to fixed-point before HDL or HLS code generation.

Version History

Introduced in R2013a

R2026b: Create HLS configuration object by using coder.config("hls")

You must specify "hls" as the input argument to create a coder.HlsConfig object for HLS code generation. In previous releases, HLS code generation required a coder.HdlConfig object created by using coder.config("hdl") with the Workflow property set to "High Level Synthesis".
