1. An integrated circuit comprising:
A. functional circuitry having functional leads; B. time stamp generator circuitry having time stamp bit leads, the time stamp bit leads including a group of most significant bit leads carrying most significant bits, a group of least significant bit leads carrying least significant bits, and a group of central bit leads, that carry central bits, that include some of the most significant bit leads and some of the least significant bit leads; C. a first bus of time stamp bit leads connected to the time stamp bit leads of the time stamp generator circuitry, the first bus including the most significant bit leads and the central bit leads; D. a second bus of time stamp bit leads connected to the time stamp bit leads of the time stamp generator circuitry, the second bus including the least significant bit leads and the central bit leads; E. client circuitry that has functional inputs coupled to the functional leads, time stamp inputs connected to only the second bus, the client circuitry including data circuitry capturing data from the functional leads with time stamp data from the time stamp inputs, and the client circuitry having scheduling outputs that output the captured data with time stamp data; and F. scheduling circuitry having time stamp inputs connected to only the first bus and client inputs connected to the scheduling outputs, the scheduling circuitry including comparator circuitry having first inputs coupled to the central bits from the first bus and second inputs coupled to the central bits from the scheduling outputs to determine a full time stamp of the captured data. |
