Priority FastTrack interconnect

The Priority FastTrack^® interconnect consists of row and column interconnect channels in a Mercury^™ device. The row interconnect routes signals throughout a row of LAB structures; the column interconnect routes signals throughout a column of LAB structures. When using the row and column interconnect, a logic element, an I/O element (also known as an I/O cell), or Embedded System Block (ESB) can drive any other LE, IOE, or ESB in a device. Priority FastTrack interconnects are faster than their equivalent non-priority lines.
