原创 SOPC Builder控制台——Virtual JTAG的最佳应用

    Quartus II 8.0中新添加了这个“系统控制台”功能。从SOPC Builder的Tools-〉Launch System Console就可以打开。下面是欢迎界面： riple

 Welcome to Altera's System Console

 This Tcl console provides access to the hardware modules instantiated in your
 FPGA. You can use the System Console for all of the following purposes:

    * To start, stop, or step a Nios II processor
    * To read or write Avalon Memory-Mapped (Avalon-MM) slaves using special
     masters
    * To sample the SOPC system clock as well as system reset signal
    * To run JTAG loopback tests to analyze board noise problems
    * To shift arbitrary instruction register and data register values to
     instantiated system level debug (SLD) nodes

 In addition, the directory $QUARTUS_ROOTDIR/sopc_builder/system_console_macros
 contains Tcl files that provide miscellaneous utilities and examples of how to
 access the functionality provided. You can include those macros in your
 scripts by issuing Tcl source commands.

    真是巧合，这和 riple 开发的Avalon-MM总线上的vjtag master总线调试工具太像了，都是通过Virtual JTAG来提供Avalon-MM的调试功能。除了基本的总线调试功能，“系统控制台”还提供Nios II处理器调试功能和一些常见的嵌入式调试工具。总线调试功能是这个控制台的最大亮点。 riple
