Creates a generated clock in the current design at a declared source by defining its frequency with respect to the frequency at the reference pin. The static timing analysis tool uses this information to compute and propagate its waveform across the clock network to the clock pins of all sequent...
Creates a clock in the current design at the declared source and defines its period and waveform. The static timing analysis tool uses this information to propagate the waveform across the clock network to the clock pins of all sequential elements driven by this clock source. ...

By default, the static timing analyzer analyzes paths within 1 cycle time of the defined clock. But sometimes you have a path which takes longer than one clock cycle, and you've designed it to sample the output after multiple clocks. For example, you have an arithmetic operation that takes...
时序分析(Static Timing Analysis,STA)是对数字电路中的信号到达时间进行分析和优化的一种方法。时序分析的结果可以用于确定电路的最大工作频率、检测设计中的潜在故障、优化电路性能等。 SDC(Synopsys Design Constraints)是一种用于描述和控制时序分析过程的命令语言。下面是一些常用的SDC命令参考。 1. create_clock:创...
