An enhanced interconnect structure for faster routing of input signals with high fan-out in APEX^™ 20KC, APEX 20KE, APEX^™ II, and ARM^®-based Excalibur^™ devices. Column I/O pins can drive the FastRow^™ interconnect, which routes signals directly into the local interconnect without having to drive through the MegaLAB^™ interconnect. FastRow lines traverse two MegaLAB structures.
