Estimating Active Serial Configuration Time

AS configuration time is dominated by the time it takes to transfer data from the serial
configuration device to the Arria II GX device. This serial interface is clocked by the
Arria II GX DCLK output (generated from an internal oscillator or an option to select
CLKUSR as external clock source). Arria II GX devices support DCLK up to 40 MHz
(25 ns).
Therefore, you can estimate the minimum configuration time as the following:
RBF Size × (minimum DCLK period / 1 bit per DCLK cycle) = estimated minimum
configuration time.
Enabling compression reduces the amount of configuration data that is transmitted to
the Arria II GX device, which also reduces configuration time. On average,
compression reduces configuration time, depending on your design.
Serial configuration devices are non-volatile, flash-memory-based devices. You can
program these devices in-system using an USB-Blaster™, EthernetBlaster, or
ByteBlaster™ II download cables. Alternatively, you can program them using a
microprocessor with the SRunner software driver.
You can perform in-system programming of serial configuration devices using the
conventional AS programming interface or JTAG interface solution.
Because serial configuration devices do not support the JTAG interface, the
conventional method to program them is using the AS programming interface. The
configuration data used to program serial configuration devices is downloaded using
programming hardware.
During in-system programming, the download cable disables device access to the AS
interface by driving the nCE pin high. Arria II GX devices are also held in reset mode
by a low level on nCONFIG. After programming is complete, the download cable
releases nCE and nCONFIG, allowing the pull-down and pull-up resistors to drive
GND and V
Altera has developed Serial FlashLoader (SFL); an in-system programming solution
for serial configuration devices using the JTAG interface. This solution requires the
Arria II GX device to be a bridge between the JTAG interface and the serial
configuration device.
