Manufacturer:TOSHIB Description:Control signals for the I/O cell registers are generated using an extra product term within each GLB, or using dedicated input pins. Each GLB has two extra product terms beyond the 80 available for the macrocell logic. The first additional product term is used as an optional shared product term clock for all the macrocells within the GLB. The second additional product term is then routed to an I/O Control Bus using a separate routing structure from the Big Fast Megablock Routing Pool and Global Routing Plane. Use of a separate control bus routing structure allows the I/O registers to have many control signals with no impact on the interconnection of the GLBs and Big Fast Megablocks. The I/O Control Bus is split into four quadrants, each servicing the I/O cell control re- quirements for one edge of the device. Signals in the control bus can be independently selected by any or all I/O cells to act as clock, clock enable, output enable, reset or preset. |
