• When cores powered down they will not affect the emulator IEEE 1149.1 (JTAG) connection because their taps are not in the scan chain. Typically, a core powered down will sever the JTAG scan chain. ICEpick solves the dynamic addition/removal of taps from the scan chain preventing the scan chain from being severed, thus enabling power aware debug. • This is a good presentation describing the functionality of the ICEPick TAP Router (or generically refered to as JTAG Route Controller or JRC). • For some devices, ICEPICK provides Wait_in_Reset functionality.
