在edk中设置project options中的Implement Design in ISE把edk中的设计导出到ise中,这个没有什么问题. 我碰到的问题是: 导出完成后,把project option中的选项改过来(仍改为: Implement Design in XPS, 像edk默认的那样),然后再依次点generator netlist,这一步也没有问题, 但是当generator bitstream时却出现这样的错误提示: Applying constraints in "system.ucf" to the design... INFO:NgdBuild:757 - "system.ucf" Line 144: The constraint for NET 'fpga_0_SysACE_CompactFlash_SysACE_MPIRQ_pin' is being attached to the equivalent NET 'SysACE_CompactFlash_SysACE_IRQ'.
