Scanning the Chains
Commands are provided for testing the Hard and Soft Devices JTAG chains directly, both of which are available from the Tools menu when a Devices view is active in the main design window.
Note: Both commands are only available when the Devices view is configured to be 'Live'. To enter this mode, ensure that the Live option in the view is enabled.
Scan Hard Chain
This command is used to interrogate the Hard Devices JTAG chain and report all physical FPGA devices that are detected.
After launching the command, the Hard Devices JTAG chain is interrogated. The Scanning Hard-Devices JTAG Chain dialog will appear listing all physical FPGA devices that are found along the chain. For each device, the following information will be listed:
- Vendor
- Family
- Device
- Package
- Speed Grade
- Temperature Grade
- ID Code.
The devices listed in the dialog will be those that appear on the Hard Devices chain in the Devices view.
Scan Soft Chain
This command is used to interrogate the Soft Devices JTAG chain and report all Nexus-enabled devices that are detected.
Before using this command ensure that the current FPGA design has been programmed into the physical device. If the device is not programmed, running this command will bring up an error dialog stating that no JTAG devices were found.
After launching the command, the Soft Devices JTAG chain is interrogated. The Scanning Soft-Devices JTAG Chain dialog will appear listing all Nexus-enabled devices that are found along the chain. For each device, the following information is listed:
- Vendor
- Family
- Device
- ID Code
The devices listed in the dialog will be those that appear on the Soft Devices chain in the Devices view.
