各位大神，在建库过程中出现的问题，在提取D触发器lib文件的时候，输入命令db_prepare -force 之后，并没有生成仿真向量，

出现了如下信息，是什么原因呢？
==============================
      DESIGN : DFF2
==============================
- bi-directional switch ( tran NET014 ) is found
- bi-directional switch ( tran NET017) is found
- bi-directional switch ( tran NET016 ) is found
- bi-directional switch ( tran NET36:D ) is found
- bi-directional switch ( tran NET36 ) is found
- bi-directional switch ( tran NET36:NET036 ) is found

- bi-directional switch ( tran NET037:NET36 ) is found
- unknown directional port ( inout : Q ) is found
- unknown directional port ( inout : D ) is found

=> no simulation
