Feature
Logic Elements
Stratix and Stratix GX device LEs include several new, advanced features
that improve design performance and reduce logic resource consumption
(see
LE features to improve device utilization.
In addition to the new LE features described in
enhancements to the chains that connect LEs together. Carry chains are
implemented vertically in Stratix and Stratix GX devices, instead of
horizontally as in APEX II and APEX 20K devices, and continue across
rows, instead of across columns, as shown in
the Stratix and Stratix GX architectures do not support the cascade
primitive. Therefore, the Quartus II Compiler automatically converts
of an LE and the register input of an
adjacent LE within the same logic array
block (LAB)
Direct path between the combinatorial
output of an LE and the fast LUT input
of an adjacent LE within the same LAB
Allows the register output to feed back
into the LUT of the same LE, such that
the register is packed with its own fan-
out LUT
Uses one set of LEs for implementing
both an adder and subtractor
Calculates outputs for a possible carry-
in of 1 or 0 in parallel
Supports direct asynchronous clear
and preset functions
