  • Slide 1
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 1 - DAAD HDL Code Generation using MATLAB/Simulink Milica Ristovi, Slobodan Lubura University of East Sarajevo, Faculty of Electrical Engineering
  • Slide 2
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 2 - DAAD Verilog i HDL codes can be generated from one of these models: - Simulink model; -Stateflow diagram; -Embedded MATLAB model.
  • Slide 3
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 3 - DAAD Steps which are neccessary for HDL Code generation in Simulink: 1.Design HDL compatible Simulink model; 2.Data type conversion from floating-point to fixed-point; 3.Use tool for compatibility check (it leads to eventual errors or problems, made durring generation); 4.HDL Code Generation; 5.Analyze of Generated HDL Code; 6.Implementation of Code on FPGA board or another similar device, analyze of device.
  • Slide 4
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 4 - DAAD Fixed-point Application Simulink Fixed-point expands possibilities of Simulink environment and enables using Data types in fixed-point format. Data Type Conversion fixdt(x,y,z), where x is number of bits, y number of bits of real part, and z number of bits of fractional part.
  • Slide 5
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 5 - DAAD Panel HDL Code Generation
  • Slide 6
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 6 - DAAD Compatibility check with HDL Coder 1)Using HDL Code Generation panel: Choosing Run Compatibility Checker; 2) Right click on subsystem which HDL Code is going to be generated, choosing HDL Code Generation Check Subsystem Compatibility; 3) Writing command in command window: >> checkhdl (Name_of_model', Name_of_subsystem'); If model is not COMPLETELY compatible with HDL Coder, code generation will not be done!
  • Slide 7
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 7 - DAAD HDL Code Generation 1)Using HDL Code Generation panel: Choosing Generate; 2) Right click on subsystem which HDL Code is going to be generated, choosing HDL Code Generation Generate HDL for Subsystem; 3) Writing command in command window: >> makehdl (Name_of_model', Name_of_subsystem'); Message: # # # HDL Code Generation Complete means end of proccess of HDL Code Generation.
  • Slide 8
  • Projekt ESSNBS Ni, November 4 th 7 th, 2012 - 8 - DAAD Report of generated HDL code Report has some parts from which we can get these information: information about version of HDL Code, and creating date; insight in virtual blocks, which cannot be seen in the model, unlike of real blocks (Simulink blocks), giving us mapping between elements (blocks and subsystems) of model and code: Codemodel links, clicking them we can see part of subsystem or block that is cide generated for; Modelcode links, enable to see generated code for any block in the model.
