  22. HDL Simulation

  23. Memory Device Simulation Models • Applies to the following Nios Memories • On Chip Memory (ROM or RAM) • SRAM (one or two IDT71V016 chips) • Flash Memory Source files (*.c & *.s) are compiled. Data files (*.mif & *.srec) are converted File is used in raw format Useful for non-standard build eg nios-build –cc –O0 hello.c String is used in raw format

  24. UART Simulation • UART rx and tx transmissions are echoed to ModelSim Console

  25. RTL Simulation Start ModelSim • Nios SOPC Builder Automatically creates simulation model plus • ModelSim Project • Testbench • Simulation Scripts • Formatted Wave Window

  45. To add or set up the Software Components, you need to go to the More “[cpu module]” Settings Tab. The Software Components section on this page will look a lot like the System Contents page (first image) but with software instead of hardware components. The functionality is the same.

  46. The first of several pages will show up. All the typical options for configuring the kernel are presented as a list of radio buttons and/or checkboxes. Once the settings are finished, they are saved and ready to be used during the compile process. The final screen will present the “Microtronix Make Console”.

  47. Since this is a new project, there is no actual source tree for us to compile. The source code repository files (included with the Microtronix Software Component) need to be copied. The files are copied by clicking the “Copy Files” button. Assuming this is cpu component “nios_0”, the source tree will be copied to the “Altera Projects\Excalibur\nios_0\uClinux” directory.

  48. Once the Copy Files button has been pressed, a small console will pop up and begin the copying of files. The “Make Dependencies” button will now be enabled and ready for use. After the copying is done, pressing the Make Dependencies button will cause a “make clean” command to be executed followed by the “make dep”.

  49. Once finished, the file “linux.srec” will be ready for you to upload to your Excalibur Board.
