Using the Board

Table 3–1 lists the advantages and disadvantages of both methods.

Active Serial Programming

This section provides active serial programming steps for both the

user-programmable and preloaded, factory-programmed EPCS64

devices.

User-Programmable EPCS64 Device

This section provides the steps to program the user-programmable

EPCS64 device’s serial flash memory via the active serial programming

method.

To program the user-programmable EPCS64 device’s serial flash memory

using the Quartus II software, follow these steps:

1. Write your custom programmer object file (.pof) into flash memory.

f For instructions on either writing a POF to flash memory or creating a

POF, refer to Quartus II Help.

2. Choose Programmer (Tools menu). The Chain1.cdf window

displays.

3. Scroll to Active Serial Programming in the Mode field.

4. To select the user-programmable EPCS64 device, set the switch (J3)

to the Down position.

If the switch (J3) is in the Up position (factory-programmed), the

factory-programmed design will be overwritten.

Table 3–1. Advantages & Disadvantages

Method Advantage Disadvantage

Conventional Simple and fast Requires separate programming

interface to configure FPGAs and

program serial configuration

devices.

SFL solution Able to configure the

FPGA and program serial

configuration devices

using the same JTAG

interface

Slow because the SFL solution

needs to configure the FPGA before

programming serial configuration

devices.
