XC5200: 5200 schematic libraries contain 'BUFGP' and 'BUFGS' symbols

説明

Keywords: BUFG, BUFGP, BUFGS, 5200, LIBRARY

Urgency: Standard

Description

5200 schematic libraries contain both BUFGP and BUFGS symbols. However, the 5k has neither BUFGP's
(primary global buffers) nor BUFGS's (secondary global
buffers) in its architecture. These types of buffers are
found only in the 4k architecture. The global buffers in the
5k (and there are 4 of them) are known as BUFG's.


ソリューション

Avoid using either the BUFGP or the BUFGS symbols in a 5k
design. Even though the BUFGP and BUFGS symbols in the 5k
schematic library are really just macros of BUFG, to prevent
any confusion between the 4k and 5k architecture, only the
BUFG should be used.
