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)
