pt读入spef文件有问题，请各位帮忙

ICC 导出Verilog和spef文件
write_verilog-no_physical_only_cells final.v
write_parasitics -format spef -output final.spef
1.pt读入Verilog时出现以下warning
Warning:Module 'FSUBC_0' in file '/home/final.v' is not used in the current design
Warning:Module 'FSUBC_1' in file '/home/final.v' is not used in the current design
.......
Warning:Module 'LATCHin 8_0' file '/home/final.v' is not used in the current design
==>请问是什么原因产生的?
2. pt读入spef时出现以下大量error
Error：Cannot find port/pin 'U2/START_STOP/U101/A' in design 'SPI_PCM'
Error：Cannot find port/pin 'U2/START_STOP/U101/N18496' in design 'SPI_PCM'

==>请问是什么原因产生的?如何解决?
请各位大侠不吝赐教，小妹万分感激。

write_verilog之前加个change_name -rule verilog试试

试了成功了

谢谢！
