  1.1  model  

    1.1.1  register-to-register  :静态时序分析,同步逻辑设计

    1.1.2  Tskew=Tc2d-Tc2s;[-a,+b];

    1.1.3  launch & latch :launch->data_arrival; latch->clock_arrival; data_required(tsu)=clock_arrival-tsu; data_required=clock_arrival+th

  1.2  equations

    1.2.1  setup = data_required - data_arrival

    1.2.2  hold = data_arrival - data_required

    1.2.3  data_required = clock - output_delay (note output delay is on data path)
