Abstract
Provision of configuration access to a programmable device such as a programmable logic device (PLD) via a boundary-scannable devices. In one embodiment a configuration controller is arranged to transfer configuration data that specify configuration access for the PLD. A scan controller is coupled to the configuration controller and arranged to generate boundary-scan signals responsive to configuration data from the configuration controller. At least one boundary-scannable device has a plurality of boundary-scan pins coupled to the scan controller, and a PLD is coupled to the boundary-scannable device.
