Design Example 2: Targeting a MAX® V Device Development Kit

In Design Example 2, the oscillator output frequency is divided by 221 before clocking a 2-bit counter. The output of this 2-bit counter is used to drive the LEDs, thereby demonstrating the internal oscillator on the MAX® V device development kit.

To demonstrate this design on the MAX® V development kit, follow these steps:

  1. Plug in the USB cable into the USB Connector to power up the device.
  2. Download the design onto the MAX® V device through the embedded Intel® FPGA Download Cable.
  3. Observe the blinking LEDs (LED[0] and LED[1]). Pressing pb0 on the demo board disables the internal oscillator and freezes the blinking LEDs at their current state.
