加入chipscope就报错,简单看了一下资源应该足够用;搞不懂。芯片是xc6slx25t
错误信息
ERRORlace:543
- This design does not fit into the number of slices available in this device
due to the complexity of
the design and/or constraints.
ERRORlace:120
- There were not enough sites to place all selected components.
Some of these failures can be circumvented by using an alternate
algorithm (though it may take longer run time). If
you would like to enable this algorithm please set the environment
variable XIL_PAR_ENABLE_LEGALIZER to 1 and try
again
ERRORack:1654
- The timing-driven placement phase encountered an error.

to control set restrictions:

A LUT Flip Flop pair for this architecture represents one LUT
paired with
one Flip Flop within a slice. A control set is a unique
combination of
clock, reset, set, and enable signals for a registered element.
The Slice Logic Distribution report is not meaningful if the design
is
over-mapped for a non-slice resource or if Placement fails.
