Output Routing Pool (ORP)
The Output Routing Pool allows macrocell outputs to be connected to any of several I/O cells within an I/O block.
This provides greater flexibility in determining the pinout and allows design changes to occur without affecting the
pinout. The output routing pool also provides a parallel capability for routing macrocell-level OE product terms. This
allows the OE product term to follow the macrocell output as it is switched between I/O cells. Additionally, the out-
put routing pool allows the macrocell output or true and complement forms of the 5-PT bypass signal to bypass the
output routing multiplexers and feed the I/O cell directly. The enhanced ORP of the ispMACH 4000 family consists
of the following elements:
Figure 7 shows the structure of the ORP from the I/O cell perspective. This is referred to as an ORP slice. Each
ORP has as many ORP slices as there are I/O cells in the corresponding I/O block.

Output Routing Multiplexers
The details of connections between the macrocells and the I/O cells vary across devices and within a device
dependent on the maximum number of I/Os available. Tables 5-9 provide the connection details.
