如上，就是结果报告上我觉得出现问题的部分， 我做的是电梯控制的一个程序，没有cell，应该就没有层了吧。
问题是：Information: Sequential output inversion is enabled. SVF file must be used for formal verification. (OPT-1208)
Information: There are 49 potential problems in your design. Please run 'check_design' for more information. (LINT-99)
我点开看了1208的解决办法是：To disable sequential output
inversion for the compile command, set the variable com-
pile_seqmap_enable_output_inversion to "false". To disable sequential
output inversion for the compile_ultra command, use the -no_seq_out-
put_inversion option to that command.
我打的指令软件不认识，试了半天也没有结果。 然后，这两个信息下面，大部分的中间reg都被remove了，再然后导致最后输入和输出都没有连接其他端口，很明显中间变量都没了，其他的差不多都悬空了。
关于这个问题，哪个大神帮忙给看一下，小弟先谢谢了 |
