联系过synopsys,他们给了这样的回信: As I further confirmed, starting from ICC 2012.06-XX versions, signoff_opt requires LCA keys, as it is recommended to use the command "focal_opt" instead, and in future the command would be obsolete. So can you please guide the users to start trying the command "focal_opt" instead. For more detailed usage information for the command "focal_opt", you can please refer to its man page. Hope this can help clarify the issue. 看来只能用focal_opt了 |
