反标SDF文件时报错# ** Error: (vsim-SDF-3251)

后仿反标SDF文件时报错# ** Error: (vsim-SDF-3251) CHIP_max.sdf(221001): Failed to find port '/test/CHIP/chip/Rs4/\O[7] '.
其中Rs4是sram，正常情况下端口应该是/test/CHIP/chip/Rs4/O[7]啊，怎么多了\？
sdf文件中定义的延时是

是名字格式的错误吗？

回复 1# staceyhoney5

如果是用primetime导出的sdf，write_sdf后面加上选项 -context verilog

icfbicfb

dc 出verilog 有没有 change_names -rules veriog -hier ?

Langjityb

我也出现了同样的问题，是在Astro中导出的，也不知道怎么改！

icfbicfb

实在不行 用perl吧， 写个脚本， 把  \ 去掉，

谢谢大家！用了3楼的方法，这个问题解决了
