According to recent research from the United States, "In this paper, an efficient framework is proposed to analyze the worst case of voltage variation of power network considering multidomain clock gating. First, a frequency-domain-based simulation method is proposed to obtain the time-domain voltage response."
"With the vector fitting technique, the frequency-domain responses are approximated by a partial fraction expression, which can be easily converted to a time-domain waveform. Then, an algorithm is proposed to find the worst-case voltage variation and corresponding clock gating patterns, through superimposing the voltage responses caused by all domains ...
