文件用到了fifo,implenment的时候出现如下错误:
NgdBuild:604 - logical block 'fifo_dvi' with type 'fifo_dvi' could not be
resolved. A pin name misspelling can cause this, a missing edif or ngc file,
case mismatch between the block name and the edif or ngc file name, or the
misspelling of a type name. Symbol 'fifo_dvi' is not supported in target
'virtex5'.
请问该如何解决?
