User Guide
■ PSO—Sets the MAX V 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.
■ PSS—Displays the MAX V PSS register value. Refer to Table 6–1 for the list of
available options.
■ PSR—Sets the MAX V 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.
1 Because the System Info tab requires that a specific design is running in the FPGA at
a specific clock speed, 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 V GX device is always the first device in the chain. The JTAG chain is normally
mastered by the On-board USB-Blaster II.
1 If you plug in an external USB-Blaster cable to the JTAG header (J10), the On Board
USB-Blaster II is disabled.
1 DIP switch SW3 selects which interfaces are in the chain. Set SW3 switch positions in
the off position to include the interface in the JTAG chain. Refer to Table 4–2 for
detailed settings.
f For details on the JTAG chain, refer to the Stratix V GX FPGA Development Board
Reference Manual.
Qsys Memory Map
The Qsys memory map control shows the memory map of the Qsys system on your
board.
