In order to quickly and accurately extract the timing information of full-custom standard cells

a method of extracting timing information of standard cells based on Hsim is proposed. After the design of the full-custom standard cell layout

it is necessary to simulate the standard cell in different load

input transition time and the fastest

slowest and typical cases

to obtain the accurate timing information. Taking the standard cell of D flip-flop as an example

this paper introduces the process of quickly extracting the timing information of standard cells by using the measurement script based on Hsim. The results show that the method achieves fast and accurate extraction of the timing information of standard cells

and the measurement results provide guidance for the use of standard cells.
