Notes to Figure 9–9:
(1) Connect the pull-up resistors to the V_CCIO power supply of the I/O bank 3C for Arria II GX devices and to V_CCPGM at a
3.0-V power supply for Arria II GZ devices.
(2) Arria II devices have an option to select CLKUSR (40 MHz maximum) as the external clock source for DCLK.
(3) The MSEL pin settings vary for different configuration voltage standards and POR delay. To connect MSEL[3..0]for
an Arria II GX device, refer to Table 9–6 on page 9–9. To connect MSEL[2..0] for an Arria II GZ device, refer to
Table 9–7 on page 9–10.
(4) Power up the USB-ByteBlaster, ByteBlaster II, EthernetBlaster, or EthernetBlaster II cable’s V_CC(TRGT) with V_CCIO 3.3 V
for Arria II GX device and V_CCPGM 3.0 V for Arria II GZ device.
You can program serial configuration devices with the Quartus II software using the
Altera programming hardware and the appropriate configuration device
programming adapter.
In production environments, you can program serial configuration devices using
multiple methods. You can use Altera programming hardware or other third-party
programming hardware to program blank serial configuration devices before they are
mounted onto PCBs. Alternatively, you can use an on-board microprocessor to
program the serial configuration device in-system using C-based SRunner software
drivers provided by Altera.
You can program a serial configuration device in-system by an external
microprocessor using SRunner. SRunner is a software driver developed for embedded
serial configuration device programming, which can be easily customized to fit in
different embedded systems. SRunner is able to read a raw programming data file
(.rpd) and write to serial configuration devices. The serial configuration device
programming time using SRunner is comparable to the programming time with the
Quartus II software.
