get_cells -h -filter "ref_name == D"
often I see a expression: get_cells -h -filter "@ref_name == D"
anyone can tell me what means "@" is ?
and I have to use "@"?

没人回答阿。
新手，期望有人帮忙解答
觉得类似 @posedge里的@ 就是满足这个条件的意思
使用filter选项时必须用
楼上的谢谢了,但是似乎现在用也可以阿
这是filter的语法要求，加上@号表示后面的变量是attribute
如 @port_direction @dont_touch @ref_name
打开dc_shell输入 man filter
里面有详细解释
非常感谢
