LSSP仿真错误

大家好，
最近按照PA_workshop_instruction.pdf做LSSP仿真
错误提示：
Error found by spectre in 'sim1',during circuit read-in.
instance 'port1' defined in the altergroup 'sim1'cannot be altered (not supported by device 'port')
instance 'port2' defined in the altergroup 'sim1'cannot be altered (not supported by device 'port')
Error found by spectre in 'sim2',during circuit read-in.
instance 'port2' defined in the altergroup 'sim2'cannot be altered (not supported by device 'port')
instance 'port1' defined in the altergroup 'sim2'cannot be altered (not supported by device 'port')
哪位大牛知道什么原因引起的?怎么去改正?拜谢！

这帖子真沉了啊

我这儿怎么不知道怎么去设置LSSP仿真，LSSP仿真那个button是灰色的，不能点击，求教！
