    Routing
    There are many resources provided in the LatticeECP/EC devices to route signals individually or as busses with
    related control signals. The routing resources consist of switching circuitry, buffers and metal interconnect (routing)
    segments.
    The inter-PFU connections are made with x1 (spans two PFU), x2 (spans three PFU) and x6 (spans seven PFU).
    The x1 and x2 connections provide fast and efficient connections in horizontal and vertical directions. The x2 and
    x6 resources are buffered, the routing of both short and long connections between PFUs.
    The ispLEVER design tool suite takes the output of the synthesis tool and places and routes the design. Generally,
    the place and route tool is completely automatic, although an interactive routing editor is available to optimize the
    design.
    Clock Distribution Network
    The clock inputs are selected from external I/O, the sysCLOCK PLLs or routing. These clock inputs are fed
    through the chip via a clock distribution system.
    Primary Clock Sources
    LatticeECP/EC devices derive clocks from three primary sources: PLL outputs, dedicated clock inputs and routing.
    LatticeECP/EC devices have two to four sysCLOCK PLLs, located on the left and right sides of the device. There
    are four dedicated clock inputs, one on each side of the device. Figure 2-6 shows the 20 primary clock sources.
