Problem Title:

2.1i, V1.5 COREGEN, DATASHEETS: the CLB count is incorrect for a 16-bit wide loadable registered adder



Problem Description:
Urgency: Standard

General Description:
The datasheet for the CORE Generator Registered Adder states that the
16-bit wide non-loadable function requires 10 CLB's, while the Registered
Loadable Adder datasheet indicates that a loadable version of the adder
with the same bit width requires only 9 CLBs.



Solution 1:

The Registered Loadable Adder datasheet is in error--both versions of a 16-bit
adder require 10 CLB's.
