Timing violation是什么意思

WebStatic Timing Analysis (STA) is one of the techniques to verify design in terms of timing. This kind of analysis doesn’t depend on any data or logic inputs, applied at the input pins. The input to an STA tool is the routed netlist, clock definitions (or clock frequency) and external environment definitions.
