The R-cell contains a flip-flop featuring asynchronous
clear, asynchronous preset, and clock enable (using the
S0 and S1 lines) control signals (Figure 1-2). The R-cell
registers feature programmable clock polarity selectable
on a register-by-register basis. This provides additional
flexibility
while
allowing
mapping
of
synthesized
functions into the SX FPGA. The clock source for the
R-cell can be chosen from either the hardwired clock or
the routed clock.
The C-cell implements a range of combinatorial functions
up to 5-inputs (Figure 1-3 on page 1-3). Inclusion of the
DB input and its associated inverter function dramatically
increases the number of combinatorial functions that can
be implemented in a single module from 800 options in
previous architectures to more than 4,000 in the SX
architecture. An example of the improved flexibility
enabled by the inversion capability is the ability to
integrate a 3-input exclusive-OR function into a single
C-cell. This facilitates construction of 9-bit parity-tree
functions with 2 ns propagation delays. At the same
time, the C-cell structure is extremely synthesis friendly,
simplifying the overall design and reducing synthesis
time.
