Stratix IV GT器件中硬IP PCI Express MegaCore功能的编译失败

对于以下行链路封装为目标的Stratix IV GT器件的设计，Quartus II软件版本10.0错误地将PCI Express硬核IP块置于底部收发器模块，该模块不包括硬IP PCI Express MegaCore功能。设计的编译失败，并显示类似于以下内容的消息：

Error: Can't assign I/O pad <“pad name”> to <pin name> because this causes failure in the placement of the other atoms in its associated channel.

Error: The transceiver block has no associated PCI Express hard IP block.

此问题会影响针对Stratix IV GT器件的PCI Express MegaCore功能的硬IP实现。
