Strarting R2025a pre-release Simscape HDL generates both floating-point and fixed-point enabled code generation from Simscape models suitable for FPGA/HIL workflows.
matlab/toolbox/hdlcoder/hdldesignpatterns/rcphil/getFPGAHILSynthesisResults.m
For fixed-point 32 bit, you need to pass dataType attribute to the function as
numerictype(0,32)
Suppose your model has two simscape networks, you need to make a DUT1, DUT2 subsystems for them and then can call the function as follows:
getFPGAHILSynthesisResults ({model/DUT1,model/DUT2'}, datatype, excelSheet, synthesisToolParams)
Here is the help text for the function parameters
function getFPGAHILSynthesisResults (models, datatype, excelSheet, synthesisToolParams)
% getFPGAHILSynthesisResults : This function takes simscape model/subsystem
% names, datatype, name of excel sheet and synthesis tool parameters as
% inputs, goes through Simscape to HDL workflow, HDL code generation,
% Synthesis and stores the synthesis results along with achievable time
% step to the excel sheet.
% models: this input expects a cell array of model/ subsystem names
% which are present in current directory or accessible on path. Eg:
% models = {'sschdlexBoostConverterModel', 'BridgeRectifier/Subsystem'};
% datatype: this input expects a numerictype object of either single,
% double or fixed point. Eg:
% datatype = numerictype('Double');
% datatype = numerictype(0,32);
% by default, we set datatype to numerictype('Single')
% excelSheet: this input expects a string/character array which
% indicates the name of the excel file where the results will be
% stored. Eg:
% excelSheet = 'SynthesisResults.xlsx'
% excelSheet = 'ResultsData'
% by default, we assign 'FPGAHILSynthesisResults.xls' as the name of
% excel sheet.
% synthesisToolParams: this input expects a struct which contains the
% information about synthesis tool parameters. by default, we set it to
% synthesisToolParams = struct('SynthesisTool', 'Xilinx Vivado',...
%'SynthesisToolChipFamily', 'Kintex7',...
%'SynthesisToolDeviceName', 'xc7k325t',...
%'SynthesisToolPackageName', 'fbg676',...
%'SynthesisToolSpeedValue' , '-1',...
%'TargetFrequency', 100);
