Claim:
1. An apparatus that compensates for misalignment on a synchronous data bus, the apparatus comprising: a replica radial distribution element, configured to receive a first signal, and configured to generate a second signal, wherein said replica radial distribution element comprises replicated propagation path lengths, loads, and buffering of a radial distribution network for a strobe; a Joint Test Action Group (JTAG) interface, configured to receive control information over a standard JTAG bus, wherein said control information indicates an amount to adjust a propagation time; and a bit lag control element, configured to measure said propagation time beginning with assertion of said first signal and ending with assertion of said second signal, and configured to generate a first value on a lag bus that indicates an adjusted propagation time, said bit lag control element comprising:
