Design Example 2: Targeting a MAX V Device Development Kit
In Design Example 2, the oscillator output frequency is divided by 2
21
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 the blinking LEDs will freeze at their
current state.
