    Abstract: In accordance with disclosed embodiments, there are provided systems, methods, and apparatuses for implementing virtual device observation and debug network for high speed serial IOS. According to one embodiment there is a functional semiconductor device, having therein a serial Input/Output interface (serial IO interface); a device fabric to carry transactions between a plurality of components of the functional semiconductor device; a transaction originator to originate a transactions and issue the transactions onto the device fabric directed toward the serial IO interface; in which the virtualized device logic is to receive the transactions at the serial IO interface via the device fabric and return responsive transactions to the device originator based on the transactions received; signature collection logic to collect signal information based on the transactions carried by the device fabric; and a signal accumulator to generate a test signature based on the signal information collected by the signature collection logic. Other related embodiments are disclosed.

    Abstract: Embodiments are generally directed to phase lock loop bypass for board level testing of systems. An embodiment of system includes a power management block for the system; multiple IO (input/output) blocks; a phase lock loop (PLL) block for each of the IO blocks, each of the phase lock loop blocks being switchable between providing an output of a PLL clock signal or providing a replacement clock signal as clocking for the respective IO block; and a read only memory for storage of firmware. In some embodiments, the firmware includes elements to enable operation of the plurality of IO blocks utilizing replacement clocking.
