 Configuring the EPCS64 in AS Mode
Figure 4-5
EPCS64 serial configuration device, perform the following steps:
 Ensure that power is applied to the DE2-115 board.
 Connect the supplied USB cable to the USB Blaster port on the DE2-115 board (See
 Configure the JTAG programming circuit by setting the RUN/PROG slide switch (SW19) to the
 The EPCS64 chip can now be programmed by using the Quartus II Programmer to select a
 Once the programming operation is finished, set the RUN/PROG slide switch back to the RUN

The DE2-115 board provides four push-button switches as shown in
switches is debounced using a Schmitt Trigger circuit, as indicated in
called KEY0, KEY1, KEY2, and KEY3 of the Schmitt Trigger devices are connected directly to the
Cyclone IV E FPGA. Each push-button switch provides a high logic level when it is not pressed,
and provides a low logic level when depressed. Since the push-button switches are debounced, they
are appropriate for using as clock or reset inputs in a circuit.
