Abstract
The relationship between the routability of a field programmable
gate array (FPGA) and the flexibility of its interconnection structures
is explored. A set of industrial circuits are implemented as FPGAs in a
range of routing structures with varying flexibility. Experiments
indicate that high flexibility is essential for the connection box that
joint the logic blocks to the routing channel, but a relatively low
flexibility is sufficient for switch boxes at the junction of horizontal
and vertical channels
