icc中输出做pt的v文件命令write_verilog -diode_ports -no_physical_only_cells -force_output_references [list of your DCAP cells] \ $RESULTS_DIR/$DESIGN_NAME.output.pt.v输出spef命令为extract_rc -coupling_cap
write_parasitics-format SPEF -output $RESULTS_DIR/$DESIGN_NAME.output.spef
现在在pt里面读入spef的时候发现很多的

等等很多是不是我的icc命令有错求各位大侠解决下很急最好能讲解下这个是什么原因引起的应该咋样解决感谢各位大侠哦
一般PT做STA需要的网表不会输出physical cells的信息,看你的命令是要把DCAP cells写到网表中。不知道是不是这样引起的!
RE: icc提取spef做pf的时候报错【解决】
需要将网标里面的TOP层模块放在最前面!
