Web9 okt. 2024 · The minimum period defines the maximum frequency at which the memory can operate given the minimum time between clocks and without affecting internal signals. For example, a minimum period arc can define the duration between a rising edge of the clock and the subsequent rising edge. WebMinimum pulse width checks are done to ensure that width of the clock signal is wide enough for the cell’s internal operations to complete. If you need a formal definition of the term, it is the interval between the rising edge of the signal crossing 50% of VDD and the falling edge of the signal crossing 50% of VDD.
