大家好,最近遇到一个难题。这几天在进行xilinx k7 接口调试,单独调试完4x PCIE 和 2x的SRIO 和 2个1x的SRIO核三个工程,都没问题。现在想将4个ip核整个到一个工程中,并编写switch将数据进行PCIE与SRIO转发,在map的时候报错。错误信息如下:
ERROR lace: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.
Unplaced instances by type:
LUT 244 (4.6)
FF 111 (11.3)
Please evaluate the following:
- If there are user-defined constraints or area groups:
Please look at the "User-defined constraints" section below to determine
what constraints might be impacting the fitting of this design.
Evaluate if they can be moved, removed or resized to allow for fitting.
Verify that they do not overlap or conflict with clock region restrictions.
See the clock region reports in the MAP log file (*map) for more details
on clock region usage.
- If there is difficulty in placing LUTs:
Try using the MAP LUT Combining Option (map lc area|auto|off).
- If there is difficulty in placing FFs:
Evaluate the number and configuration of the control sets in your design.
The following instances are the last set of instances that failed to place:
0.

看错误提示可能是资源不够,但是我看了下独立三个工程的话资源应该是完全够的。一下是整个后map的报告:

Number used exclusively as route-thrus: 52
Number with same-slice register load: 0
Number with same-slice carry load: 52
Number with other load: 0
Slice Logic Distribution:
Number of LUT Flip Flop pairs used: 36,711
Number with an unused Flip Flop: 11,293 out of 36,711 30%
Number with an unused LUT: 12,181 out of 36,711 33%
Number of fully used LUT-FF pairs: 13,237 out of 36,711 36%
Number of unique control sets: 1,087
Number of slice register sites lost
to control set restrictions: 3,864 out of 82,000 4%
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.
OVERMAPPING of BRAM resources should be ignored if the design is
over-mapped for a non-BRAM resource or if placement fails.
