Chapter 6: Board Test System 6–5

Using the Board Test System

■ PSO—Sets the MAX II PSO register. The following options are available:

■ Use PSR—Allows the PSR to determine the page of flash memory to use for

FPGA reconfiguration.

■ Use PSS—Allows the PSS to determine the page of flash memory to use for

FPGA reconfiguration.

■ PSR—Sets the MAX II PSR register. The numerical values in the list corresponds to

the page of flash memory to load during FPGA reconfiguration. Refer to Table 6–1

for more information.

■ PSS—Displays the MAX II PSS register value. Refer to Table 6–1 for the list of

available options.

■ SRST—Resets the system and reloads the FPGA with a design from flash memory

based on the other MAX II register values. Refer to Table 6–1 for more information.

1 Because the Config tab requires that a specific design is running in the FPGA, writing

a 0 to SRST or changing the PSO value can cause the Board Test System to stop

running.

JTAG Chain

The JTAG chain control shows all the devices currently in the JTAG chain. The Stratix

IV GX device is always the first device in the chain.

1 S

etting DIP switch SW6.1 to the off position includes the MAX II device in the JTAG

chain.

Board Information

The Board information controls display static information about your board.

■ MAX II ver—Indicates the version of MAX II code currently running on the board.

The MAX II code resides in the <install

dir>\kits\stratixIVGX_4sgx230_av\examples directory. Newer revisions of this

code might be available on the Audio Video Development Kit, Stratix IV GX

Edition page of the Altera website.

Read/Write

Capability Description

System Reset

(SRST)

Write only Set to 0 to initiate an FPGA reconfiguration.

Page Select Register

(PSR)

Read / Write Determines which of the up to eight (0-7) pages of flash

memory to use for FPGA reconfiguration. The flash memory

ships with pages 0 and 1 preconfigured.

Page Select Override

(PSO)

Read / Write When set to 0, the value in PSR determines the page of

flash memory to use for FPGA reconfiguration. When set to

1, the value in PSS determines the page of flash memory to

use for FPGA reconfiguration.

Page Select Switch

(PSS)

Read only Holds the current value of the rotary switch (SW2).
