set_fp_pin_constraints 约束后失败出现问题

kaisen2411

对一个spi数字电路跑后端，由于是模拟电路的一部分，所以不需要加pad，

使用pin_con.tcl文件约束顶层port


set_pin_physical_constraints -pin_name {PORB_I} -layers {METAL3} -width 0.6 -depth 0.6 -side 1 -order 1
set_pin_physical_constraints -pin_name {RST} -layers {METAL3} -width 0.6 -depth 0.6 -side 1 -order 2
set_pin_physical_constraints -pin_name {CLK} -layers {METAL3} -width 0.6 -depth 0.6 -side 1 -order 3
set_pin_physical_constraints -pin_name {CS_I} -layers {METAL3} -width 0.6 -depth 0.6 -side 1 -order 4

......
icc log如下：

请问有没有人知道是什么原因，怎么解决呀

请问这个pin位置不能被约束得问题解决了吗，我也遇到这个问题了
