Schnell und effizient durch Automatische Codegenerierung Andreas Uschold MathWorks © 2015 The MathWorks, Inc. 1 ITK Engineering Develops IEC 62304 – Compliant Controller for Dental Drill Motor with Model-Based Design Challenge Develop and implement field-oriented controller software for sensorless brushless DC motors for use in dental drills Dental drills featuring ITK Engineering’s sensorless brushless motor control. Solution Use Model-Based Design with Simulink, Stateflow, and Embedded Coder to model the controller and plant, run closed-loop simulations, generate production code, and streamline unit testing “Model-Based Design with Results through early verification, § Development time halved § Hardware problems discovered early § Contract won, client confidence established Simulink enabled us to reduce costs and project risk shorten time to market on an IEC 62304–certified system, and deliver high-quality production code that was first-time right.” Michael Schwarz ITK Engineering 2 Model-Based Design Verification and Validation Development Process Requirements System Design Environment Physical Components Algorithms System-Level Specification Component Design Subsystem Design User Acceptance Testing Complete Integration & Test Integration testing System-Level Integration & Test Code Verification and Validation Embedded Software Digital Electronics C, C++ MCU Subsystem Integration & Test VHDL, Verilog DSP FPGA ASIC Integration Implementation Subsystem Implementation 3 Model-Based Design Automatic Code Generation Requirements • C/C++, VHDL and PLC-Code Generation from one model VHDL, Verilog C, C++ System Design MCU • Support for Fixed Point Data Format User Acceptance Testing DSP FPGA Structured Text ASIC PLC Environment • Automatic scaling • Supported in Simulation and Code-Generation Physical Components Integration testing PLC Coder (Structured Text) • Easy integration of legacy C/C++-Code Algorithms development Componentindependent Design of the target Embedded Coder (C, C++) EmbeddedDSP & µC Digital Software Electronics C, C++ MCU PLC System-Level Integration & Test System-Level Specification • System Subsystem Design Complete Integration & Test HDL Coder Code (VHDL, Verilog) Verification and Validation Subsystem Integration & Test FPGA & ASIC VHDL, Verilog DSP FPGA ASIC Integration Implementation Subsystem Implementation 4 Model-Based Design Code Generation Workflow Controller 5 Model-Based Design C/C++ - Code Generation Products and Hardware Support Packages Embedded Coder Simulink Coder http://de.mathworks.com/hardware-support/ MATLAB Coder 6 Model-Based Design Verification and Validation Development Process Requirements System Design Environment Physical Components Algorithms System-Level Specification Component Design Subsystem Design User Acceptance Testing Complete Integration & Test Integration testing System-Level Integration & Test Code Verification and Validation Embedded Software Digital Electronics C, C++ MCU Subsystem Integration & Test VHDL, Verilog DSP FPGA ASIC Integration Implementation Subsystem Implementation 7 Model-Based Design Verification and Validation Controller ? *.c / *.h *.cpp / *.hpp Communication Interfaces Comm Drivers Generated Algorithm Code Input Drivers Included Target Optimized Code Sensors A B M Output Drivers Actuators ?
