Device chain pane

Allows you to view a graphical representation of the JTAG device chain. You can use the graphical representation to choose and activate one device while bypassing other devices in the JTAG chain. This allows you to easily specify the scan pattern of the active device and not have to specify the padding bits required to bypass the non-active devices in the JTAG chain.

A blue graphical image of a device indicates an active device, while a white graphical image indicates a bypassed device.
