Figure 4-46: Breakpoint Added
7. Let the program run by clicking the green Continue button or by pressing F8. The code will stop at the
breakpoint.
Note: This ensures that when you try to access the soft IP registers, they are already available. If you
try to access the soft IP registers before the FPGA is programmed or before the bridges are
open, the debugger generates a memory access abort and the debugging session fails.
8. Maximize the Registers dialog box and expand the Peripherals register group
9. Scroll to the end of the list and expand the altera_avalon_pio_led_pio_s1 group. It corresponds to the
soft IP GPIO module that controls the FPGA LEDs on the board.
10.Expand the DATA register. This register contains the values that are driven on the GPIO pins to
control the LEDs.
