Target Frequency
The Target frequency control allows you to specify the frequency of the clock. Legal
values are between 10 and 810 MHz with eight digits of precision to the right of the
decimal point. For example, 421.31259873 is possible within 100 parts per million
(ppm). The Target frequency control works in conjunction with the Set New
Frequency
control.
Reset Si570
The Reset Si570 control sets the Si570 programmable oscillator to the default
frequency of 100 MHz.
Set New Frequency
The Set New Frequency control sets the Si570 programmable oscillator frequency to
the value in the Target frequency control. Frequency changes might take several
milliseconds to take effect. You might see glitches on the clock during this time. Altera
recommends resetting the FPGA logic after changing frequencies.
Configuring the FPGA Using the Quartus II Programmer
You can use the Quartus II Programmer to configure the FPGA with your own .sof.
Before configuring the FPGA, ensure that the Quartus II Programmer and the
USB-Blaster driver are installed on the host computer, the USB cable is connected to
the FPGA development board, power to the board is on, and no other applications
that use the JTAG chain are running.
To configure the Stratix IV GX FPGA, perform the following steps:
1. Start the Quartus II Programmer.
2. Click Auto Detect to display the devices in the JTAG chain.
3. Click Add File and select the path to the desired .sof.
4. Turn on the Program/Configure option for the added file.
5. Click Start to download the selected file to the FPGA. Configuration is complete
when the progress bar reaches 100%.
1 Using the Quartus II programmer to configure a device on the board causes other
JTAG-based applications such as the Board Test System and the Power Monitor to lose
their connection to the board. Restart those applications after configuration is
complete.
