Programmable Interconnect Matrix
The PIM consists of a completely global routing matrix for signals
from I/O pins and feedbacks from the logic blocks. The PIM
provides extremely robust interconnection to avoid fitting and
density limitations.
The inputs to the PIM consist of all I/O and dedicated input pins
and all macrocell feedbacks from within the logic blocks. The
number of PIM inputs increases with pin count and the number
of logic blocks. The outputs from the PIM are signals routed to
the appropriate logic blocks. Each logic block receives 36 inputs
from the PIM and their complements, allowing for 32-bit opera-
tions to be implemented in a single pass through the device. The
wide number of inputs to the logic block also improves the routing
capacity of the Ultra37000 family.
An important feature of the PIM is its simple timing. The propa-
gation delay through the PIM is accounted for in the timing speci-
fications for each device. There is no additional delay for
traveling through the PIM. In fact, all inputs travel through the
PIM. As a result, there are no route-dependent timing param-
eters on the Ultra37000 devices. The worst-case PIM delays are
incorporated in all appropriate Ultra37000 specifications.
Routing signals through the PIM is completely invisible to the
user. All routing is accomplished by software-no hand routing
is necessary. Warp
and third-party development packages
automatically route designs for the Ultra37000 family in a matter
of minutes. Finally, the rich routing resources of the Ultra37000
family accommodate last minute logic changes while maintaining
fixed pin assignments.
