What is Recovery & Removal Time?...

recovery and removal time

these r regarding async ips to the FF.

before the active edge of the clk, async signal should be stable for the period of recovery time.

similarly removal, after the clk edge, this much of the period async signal should be stable.

async removal time

recovery is similar to SETUP requirement. This is generally used for ASYCN signals i/p to FF such as RESET.

removal is like HOLD requirement. This is generally used for ASYCN signals i/p to FF such as RESET.

async recovery time

Recovery and Removal is the concept about the time between internal register clock and reset signal.
Recovery is the offset of the time when clock become asserted from the time when reset signal is desserted.
Removal is the offset of the time when reset become asserted from the time when clock signal is desserted.

reset removal timing violation

A recovery time is a limit of the time between the release of an
asynchronous control signal from the active state and the next active clock
edge.

A removal time is a limit of the time between an active clock edge
and the release of an asynchronous control signal from the active state.

Hi,

If you want to know the effect of recovery time violation in a design, please refer the following blogspot.
