3-State Buffers
Introduction
Each Virtex-II CLB contains two 3-state drivers (TBUFs)
that can drive on-chip buses. Each 3-state buffer has its
own 3-state control pin and its own input pin.
Each of the four slices have access to the two 3-state buffers
through the switch matrix, as shown in
neighboring CLBs can access slice outputs by direct
connects. The outputs of the 3-state buffers drive horizontal
routing resources used to implement 3-state buses.

The 3-state buffer logic is implemented using AND-OR logic
rather than 3-state drivers, so that timing is more predictable
and less load dependent especially with larger devices.
Locations/Organization
Four horizontal routing resources per CLB are provided for
on-chip 3-state buses. Each 3-state buffer has access
alternately to two horizontal lines, which can be partitioned as
shown in
SelectRAM memory and multiplier or I/O blocks are skipped.

each Virtex-II device. The number of 3-state buffers is twice
the number of CLB elements.
