Auto Detect Command (Processing Menu)

You access this command by clicking Auto Detect on the Processing menu. This command is available only when the Programmer window is open.

Detects devices in a chain and automatically adds Intel-supported devices to the Device list in the Programmer in the order in which they exist in the device chain. The Intel® Quartus® Prime software also recognizes non-Intel devices you define in the New Device dialog box and adds them to the Device list. Unknown devices in a device chain are listed as UNKNOWN_<JTAG IDCODE> in the Device list.

If there are devices in the Device list in the Programmer when you click Auto Detect, the Intel® Quartus® Prime software compares the devices in the Device list with the devices in the chain. The Intel® Quartus® Prime software then reorders the devices in the Device list, along with associated programming files in the File list, to match the device order in the chain. The Intel® Quartus® Prime software inserts or removes devices in the Device list as needed to match the devices in the chain. When two devices have the same JTAG IDCODE, the Programmer opens a dialog box that lists the devices, and allows you to specify a new code for one of the devices. When Auto Detect fails to scan the chain, an error message prompts you to open the JTAG Chain Debug Tool to analyze the failure.
