  1. Model-Based Design and SDR Fabio Ancona Sundance Italia SRL CEO – Sales Director

  2. Model-Based Design • Designing complex systems needs new design methodologies: • Binary coding. • Assembly coding. • C programming. • Model-Based Designing. www.sundance.com

  3. Aim of Model-Based Design • Aim of Model-Based Design methodology is: • Simplify design entry. • Graphical design entry. • Hierarchical system design. • Design reuse: • Design library. • Sharing designs. www.sundance.com

  4. Model-Based Design tools • Properties of a good Model-Based Design tool: • Easy design entry. • Design simulation. • Code generation. • Testing on real hardware. www.sundance.com

  5. Easy design entry • Easy design entry helps to reduce the system design time. • The design entry tool should be: • Graphical. • Library for different functions. • Library for hardware resources. www.sundance.com

  6. Design simulation • Simulation helps to find error and bugs in the early stages of design entry. • The simulation should be: • Accurate. • Target processor specifications. • Simple and fast. www.sundance.com

  7. Code generation • Model to C source code. • Generated code should be: • Optimized. • Suitable for embedded systems. • Be fast and without user intervention. • Provide tools to generate downloadable application from generated source code. www.sundance.com

  8. Testing • Testing generated code on target hardware. • Hardware In the Loop (HIL) testing. • Designed system runs on target hardware. • Workstation send test vectors to system under test. • Output of system under test is analyzed by workstation. www.sundance.com

  9. Model-Based Design tools • Simulink/Matlab (The MathWorks Inc) • LabView (National Instruments) • Suitable for test and measurement design. • Limited capability for embedded system development • VEE (Agilent) • Suitable for developing test and measurement systems. • No code generation capability. www.sundance.com

  10. Simulink/Matlab • Suitable for number crunching systems such as SDR. • Large selection of code generation targets. • SMT6050 : targeting Sundance DSP modules. • code optimization options. • HIL testing (SMT6050) www.sundance.com

  11. Simulink + SMT6050 • Simulink (The MathWorks Inc) • Design Entry • SMT6050 (Sundance) • Code generation compatible with Sundance DSP modules. www.sundance.com

  12. Simulink • Interactive graphical user interface for system design. • Simulating designed system. • Extensive and expandable libraries of predefined blocks. www.sundance.com

  13. SMT6050 • Code generator for Simulink • Generate optimized, embeddable C source code targeting Sundance DSP modules. • Add blocks representing hardware resources (input/output, ADC, DAC). • Generate code for HIL testing. www.sundance.com

  14. SDR design • Purpose: • To demonstrate how self sufficient code could be generated using Simulink + SMT6050 • System • FM3TR reference waveform modulator/demodulator. • Design • Simulation • Code generation • HIL testing www.sundance.com

  15. FM3TR • Multi-band, Multi-waveform, Modular, Tactical Radio (FM3TR) waveform. • A reference waveform for SDR Forum consideration. • Provides the SDR Forum and its members a non-proprietary, complex narrowband frequency-hopping waveform for implementation as a common test and demonstration tool. There are a number of systems [US, UK, GE, FR] that have already implemented and successfully demonstrated interoperability using this test waveform. www.sundance.com

  16. FM3TR • Frequency range: 30-400KHz • Channel spacing: 25kHz • Modulation type: CPFSK • Modulation rate: 25kbps • Frequency hopping - 250-500 hops/second • Framing, packetization • 16kbps CVSD Voice coder • Data channel with Reed-Solomon Coding www.sundance.com

  17. FM3TR modulator/demodulator • Implemented and simulated in Simulink. • Test bench. www.sundance.com

  18. FM3TR modulator • Modulate the incoming signal according to FM3TR standard. www.sundance.com

  19. FM3TR Demodulator • Compatible with developed modulator. www.sundance.com

  20. Hardware • Sundance SDR kit. • TMS320C6416 running at 1GHz. • 2 ADC sampling rate up to 105 MHz. • 2 DAC sampling rate up to 400 MHz. • PCI interface for high speed data communication with PC. www.sundance.com

  21. Code generation (SMT6050) • Targeted Sundance SDR kit. • Building all of the required library automatically. • Libraries were compiled and linked using the specified complier and linker switches. • All required files was generated. • C source files. • Linker command file. • Make file. • Batch file. www.sundance.com

  22. HIL testing • All of the code for HIL testing is generated automatically • Communicating with host. • Synchronization. • Data flow synchronization. www.sundance.com

  23. HIL testing FM3TR • Modulator/demodulator runs on DSP. • Code for Modulator/Demodulator generated. • Test bench runs on host. • New test bench model is created. www.sundance.com

  24. FM3TR code generation • Modulator/demodulator dragged and drops to a new model. • Host communication blocks added into it. www.sundance.com

  25. HIL test bench • Modulator/demodulator subsystems is replaced by SMT310 block. www.sundance.com

  26. HIL testing • Generated application from modulator/ demodulator was loaded into DSP. • Test bench ran on host. • The validity of generated code was proved. www.sundance.com

  27. Generated code: • Generated code is fully documented: • Comment on source code. • Code generation report with a hyperlink from Simulink block to the generated code. www.sundance.com

  28. “Is code good ?” • Yes, automatically generated code is good from many perspectives: • speed • memory utilization • reliability • optimization options • one can incorporate legacy/custom code … • … www.sundance.com

  29. Conclusion • The next innovation in system design is Model-Based Design. • An effective Model-Based Design can reduce the development time. • HIL testing is a suitable technique for testing generated code. • Simulink + SMT6050 is an effective combination for developing SDR systems using Model-Based Design Technique. • Generate code targeted Sundance SDR modules. • Generate all codes for HIL testing. www.sundance.com
