"ERROR:Place:1721 - The current designer locked placement of the IOBs GLOBAL_RESET and MC_MC_IN(1) makes this design unroutable due to a physical routing limitation. This device has a shared routing resource connecting the ICLK and OTCLK pins on pairs of IOBs. This restriction means that these pairs of pins must be driven by the same signal or one of the signals will be unroutable. Before continuing with this design, please unlock or move one of these IOBs to a new location."
