| 1. For an integrated circuit (IC) comprising a configurable circuit arrangement and a debug network, wherein said configurable
circuit arrangement comprises configurable logic circuits for performing logical operations and configurable routing circuits
for routing signals between the configurable logic circuits, said debug network for monitoring data, a method comprising:
configuring at least a subset of said configurable logic circuits and a first subset of said configurable routing circuits
to implement a design on said IC, wherein said configuring configures a plurality of configurable logic circuits and a plurality
of configurable routing circuits to implement a plurality of operations of said design; and
configuring a second subset of said configurable routing circuits to pass data from said implemented design away from a first
congested location of said debug network to a second, less congested location of said debug network;
wherein said debug network passes data from the second, less congested location out of the configurable circuit arrangement.
