3 Using the USB Download Cable
To start using the USB Download Cable, you must install the drivers on your system
and set up the hardware in the Quartus
®
Prime software. Intel recommends that you
use the latest version of the Quartus Prime software.
To program or configure the device, connect the host system to the device board using
the USB Download Cable and initiate the programming or configuration using the
Quartus Prime Programmer. You can also use the cable with the Quartus Prime
SignalTap
®
II Logic Analyzer for logic analysis.
3.1 Installing the USB Download Cable Driver on Windows
1.
Locate the USB Download Cable driver in \<Quartus Prime system
directory>\drivers\usb-blaster.
If the driver is not in your directory, download the driver from www.altera.com/
support/software/drivers.
2. Connect the USB Download Cable to your PC.
3. Open Device Manager. In the Other devices tab, select and right click USB-
Blaster. Then, click Update Driver Software.
4.
Click Browse. Browse to \<Quartus Prime system directory>\drivers
\usb-blaster and click Next.
The Windows security warning is displayed.
5. Click Install to begin installing the driver.
6. Click Finish when the driver is installed.
7. Restart your system.
