reset recovery time
Hi All
In the Async Reset based designs the Reset covery and reset removal time plays an important role. We go for the concept even like Async reset assertion and Synchronous removal.
1. My question is when the Async reset is asserted it doesnot looks for the clock signal. Is there any chance of flops going to metastable state when Asyc reset is asserted?
2. The removal time we talk about is the time offset between Clock Deassertion and Reset Assertion. How to take care of it ?
3. If we talk about the reset Synchronizer at the assertion time also then wht is the use of Async reset as it will be synchronized to the clock signal so why not then use synchronous Reset?
