WebCTS is the process of insertion of buffers or inverters along the clock paths of ASIC design in order to achieve zero/minimum skew or balanced skew. Before CTS, all clock pins are driven by a single clock source. CTS starting point is clock source and CTS ending point is clock pins of sequential cells. WebThe set_input_delay and set_ouput_delay commands are used to constraint input and output port delays. The set_input_delay command is used to specify how much time is used by external logic. DC then calculated how much time is left for internal logic and tries to meet it. set_input_delay 4.5 -clock CLK1 [get_ports IN1]
