Arria 10 10AS032E3F29I2SG MAC IP 时序违例

[Jekyll]

在使用Arria 10 10AS032E3F29I2SG的时候出现以下路径时序建立时间为负值，查看路径发现是1G/10G mac ip 里的路径，该路径的工作频率是312.5Mhz，时序违例如下附件，请问：
此路径建立时间为负值是否正常？是否需要添加某些约束改善此路径？

Hi,

I have a discussion about this issue with my team. In your case, the negative value of the timing is considered as abnormal. The failure seem in the IP, you need to check whether the IP is closed if standalone. If the failure seem inside the IP, you might check back your design or maybe your design is having some issue.
