<p>To Synchronize the FEE64 ASIC clocks to rise at the same timestamp time use the System function <em>Synchronise the ASIC clocks</em> in the System Wide Checks browser page.</p> <p>The Server will read the current timestamp value and calculate, based on the number of FEEs and the access delay, a timestamp value sometime in the future. F_stamp</p> <p>F_stamp is written to each FEE and the synchronization is enabled. </p> <p>In a state machine in the FEE ASIC clock control, logic is enabled to synchronize its ASIC clock. It compares the current timestamp with F_stamp and if the current timestamp is >= F_stamp then it will start the ASIC clock.</p> <p>The report in the browser log window gives the 3 LSBs of the timestamp at the instant the ASIC clock is started. They should all be the same. They are from the 10ns timestamp.</p> <p> </p> Encoding: HTML ELCode plain Suppress Email notification
