  12. 2.建立 SOPC 建立 SOPC

  13. 啟動 SOPC Builder • 於Qaurtus 下啟動SOPC Builder • 選單 “Tools SOPC Builder…”, 或 • 按下 SOPC Builder ICON 建立 SOPC

  14. 輸入 SYSTEM 資訊 建立 SOPC

  15. Add “On-Chip Memory” 建立 SOPC

  16. Add “NIOS II Processor” 建立 SOPC

  17. Add “JTAG UART” 建立 SOPC

  18. Add “LCD” 建立 SOPC

  19. 完成SOPC 設計 建立 SOPC

  20. Generate Code - DE2_70_SOPC.V (top) - DE2_70_SOPC.PTF 建立 SOPC

  21. SOPC_DE2_70_SOPC.v (內容) 建立 SOPC

  22. SOPC_DE2_70_SOPC.v(SYMBLE) 建立 SOPC

  23. 3. 完成Ｑuartus Top 完成Quartus Top

  24. 目的:連接SOPC與週邊 完成Quartus Top

  25. New Verilog File 完成Quartus Top

  26. Rename Verilog File 完成Quartus Top

  27. Coding MY_FIRST_SOPC.v module MY_FIRST_SOPC ( //////////////////// Clock Input //////////////////// iCLK_50, // 50 MHz //////////////////// LCD Module 16X2 //////////////// oLCD_ON, // LCD Power ON/OFF oLCD_BLON, // LCD Back Light ON/OFF oLCD_RW, // LCD Read/Write Select, 0 = Write, 1 = Read oLCD_EN, // LCD Enable oLCD_RS, // LCD Command/Data Select, 0 = Command, 1 = Data LCD_D, // LCD Data bus 8 bits ); 完成Quartus Top

  28. Port Declaration // PORT declarations //================================================== //////////////////////// Clock Input //////////////////////// input iCLK_50; // 50 MHz //////////////////// LCD Module 16X2 //////////////////////////// inout [7:0] LCD_D; // LCD Data bus 8 bits output oLCD_ON; // LCD Power ON/OFF output oLCD_BLON; // LCD Back Light ON/OFF output oLCD_RW; // LCD Read/Write Select, 0 = Write, 1 = Read output oLCD_EN; // LCD Enable output oLCD_RS; // LCD Command/Data Select, // 0 = Command, 1 = Data 完成Quartus Top

  29. Power On LCD //========== 16*2 LCD Module assign oLCD_ON = 1'b1; // LCD ON assign oLCD_BLON = 1'b1; // LCD Back Light 完成Quartus Top

  30. Connect SYSTEM // Structural coding //================================================== DE2_70_SOPC u1 ( // 1) global signals: .clk(iCLK_50), .reset_n(1), // the_lcd .LCD_E_from_the_lcd(oLCD_EN), .LCD_RS_from_the_lcd(oLCD_RS), .LCD_RW_from_the_lcd(oLCD_RW), .LCD_data_to_and_from_the_lcd(LCD_D) ); endmodule 完成Quartus Top

  31. Pin Assignment - Analysis • 選單 “FileSave” save “MY_FIRST_SOPC.V” • 選單 “ProcessingStartStart Analysis & Elaboration” 完成Quartus Top

  32. 開啟Pin Planner 完成Quartus Top

  33. 輸入PIN角位置 滑鼠雙擊後, 打B2 完成Quartus Top

  34. 4. Compile/Download Compile/Download

  35. Compile Compile/Download

  36. 1 3 2 4 Download • DE2_70 左邊SWITCH 須切至 “RUN” Compile/Download

  37. 2 1 3 No USB-Blaster? Compile/Download

  38. Hello World “軟”體實作

  39. Start NIOS II IDE 7.2 • Windows選單“開始所有程式AlteraNIOS II EDS 7.2NIOS II IDE 7.2” New Project

  40. Setup Workspace • 選單“FileSwitch Workspace…” C:\DE2_70\MY_FIRST_SOPC\ software\project_hello New Project

  41. 3 4 1 C:\DE2_70\MY_FIRST_SOPC\ DE2_70_SOPC.ptf 2 5 New Nios Project • 選單“FileNewNios II C/C++ Application” New Project

  42. Editor Project Management NIOS II IDE 介面 Coding

  43. Coding – hello_world.c #include <stdio.h> #include <stdlib.h> #include "system.h" void hello_lcd(void); int main() { printf("Hello from Nios II!\n"); hello_lcd(); return 0; } • void hello_lcd(void){ • FILE *pLCD; • char szHello[] = "DE2_70\nHello\n"; • pLCD = fopen(LCD_NAME, "w"); • if (pLCD){ • fwrite(szHello, strlen(szHello), 1, pLCD); • //fclose(pLCD); • }else{ • printf("failed to open LCD\n"); • } • } Coding

  44. Menu “ProjectBuild All” Sytem.h Compile Compile

  45. Download Hardware .SOF • Menu “ToolsQuartus II Progammer” 5 3 2 1 C:\DE2_70\MY_FIRST_SOPC\ MY_FIRST_SOPC.sof 4 Download HW

  46. 2 1 Run Run

  47. Run Configuration Target Connection NIOS II Hardware 1.滑鼠 左鍵雙擊 3 2 4 只有第一次未指定硬體時 才會出現此畫面 5 Run

  48. 結果 • LCD 上出現 • NIO2 IDE Console 出現 DE2_70 Hello Run
