Experiment to test virtual jtag on EP2C5 development board.
This is nothing more than a port of the virtual jtag tutorial for the DE0-Nano board design for the dirt cheap EP2C5 board that can usually be found on eBay for around $13.
When the design is loaded, one LED is connected to a fixed rate blinker, used as sanity test that all is well. The two other LEDs are connected to bit 0 and bit 6 of a DR shift register instead. There are both on after the bitstream has been loaded.
During execution of the vjtag_led_counter program, one LED will be blinking very quickly, while the other will simply switch from 1 to 0.
Start virtual JTAG server:
quartus_stp -t vjtag_client_control.tcl
Send command to virtual JTAG server:
python vjtag_led_counter.py
