      2 Quick hack commandline tools to interact with Altera FPGA Virtual JTAG interfaces,
      3 using the USB Blaster device (as integrated on Terasic dev boards, etc).
      4 
      5 Not terribly fancy or optimized but only depends on libusb-1.0
      6 
      7 Currently does not support multiple devices on the chain.
      8 
      9 jtag.c - provides simple jtag interface
     10 jtag-virtual.c - provides simple virtual jtag interface
     11 
     12 jload.c - example of using the virtual jtag interface for a downloader interface
     13           with a CTRL/ADDR/DATA register set.  CTRL[0] asserts reset, writes to
     14           DATA store to [ADDR] and auto-increment ADRR.
     15 
     16 jinfo.c - dumps idcode and virtual jtag hub and device info table

     19 Why?  Scripting the Altera quartus_stp tool in TCL was driving me nuts.
