Hold time violation解法

NettetHold time violation is a violation of the hold time requirement. If the datasheet says the minimum required hold time is 10 ns and you change the data 5 ns after the clock edge, then you have committed a hold time violation and there is no guarantee which data value will end up on the flipflop output.

NettetWhat is Hold Time? Hold time is the total amount of time a caller spends in an agent-initiated hold status. In other words, the caller connects with an agent, they typically have some discussion, and then the agent puts them on hold, meaning the call is not disconnected but the caller is in a sort of limbo until the agent takes them back off hold.
