Logic clock data. 1-14 Specifying Timing Constraints in ASIC … WebDefinition of Hold time : Hold time is defined as the minimum amount of time after the clock's active edge during which data must be stable. Similar to setup time, each sequential element needs some time for data to remain stable after clock edge arrives to reliably capture data. This duration is known as hold time.

WebThen New hold time (Thold new) = Thold - Tcomb = 2ns - 1 ns =1ns (positive hold time) If Tcomb = 2ns Thold new = Thold – Tcomb = 2ns – 2ns = 0 ns (zero hold time) If the comb logic is equal to internal clock delay then our hold time will be zero if hold time is zero it means no need to hold the data after the clock edge has arrived.

WebOct 27, 2024 · You will need to add delays to the clock and/or data signal to the specific flip-flop in question. Adding delay to the data input increases the effective setup time, while adding delay to the internal clock signal increases the effective hold time. The clock-to-q delay is controlled by delays added to the input clock as well as to the output q. Web12.2.
