无法路由设计

Xilinx FPGA ultrascale vivado 2016.2该设计利用80%的设备,早期用于路由与合成stratagy  - 流动交替可路由性&
congestoion扩展逻辑高实现现在我必须在顶层模块中创建一个小的4位计数器,并且设计不是路由。我尝试了多次,结果是相同的(尽管重叠节点的设置,保持和数量确实发生了变化
每次跑步。)
我有什么选择,除了减少逻辑我不能再减少逻辑,请建议一些方法来获得一个干净的bitfile.Thanks

Xilinx fpga ultrascale vivado 2016.2

The design is utilizing 80% of the device and earlier it used to route with synthesis stratagy - flow alternate routability & congestoion spread logic high for implementation

now I had to create a small 4 bit counter in the top module and the design is not routing.
I tried multiple times and the result is same ( although the set up , hold and no. of overlap nodes does change with every run. )

What are the options do I have except reducing logic

I cannot reduce the logic anymore, please suggest some way to get a clean bitfile.

Thanks

你好@ ultragreen
路由器是否因拥塞而失败?
你能上传位于.runs  - > impl_1位置的runme.log文件吗?
如果失败是由于拥塞造成的,请试用ARhttps://www.xilinx.com/support/answers/66314.html上的建议。
还尝试使用增量编译,因为工作和非工作设计之间的设计变化似乎很小。
谢谢,迪皮卡.----------------------------------------------

Hi @ultragreen
 
Is the router failing due to congestion? Can you upload the runme.log file located in .runs-->impl_1 location?
 
 
Try out the suggestions from AR https://www.xilinx.com/support/answers/66314.html  if the failure is due to congestion.
 
Also try using incremental compile as the design changes between working and non-working designs seem to be minimal.
Thanks,
Deepika.

@ Deepika,我在之前成功运行的放置检查点上使用增量运行。
我应该使用路由检查点进行增量运行吗?谢谢

@ Deepika,
I am using incremental run on top of placement check point of previous sucessful run . Should I use Routed checkpoint for incremental run ?

Thanks
