What is Asynchronous reset?
A reset that initializes flip-flops as soon as the reset signal is asserted, regardless of the clock. Release should be synchronized to the clock.
Field: HDL & Verification
Asynchronous reset in the explanations
If an asynchronous reset is released just before or after a clock edge, the timing requirements for release are violated, and one flip-flop may start in this cycle while another starts in the next.
In circuits using asynchronous reset, why is reset release …This is an asynchronous reset.
What type of reset does the code above have, and how does i…An asynchronous reset uses the flip-flop's reset pin directly, so it acts at once even without a clock, but if release happens near a clock edge, flip-flops may come out of reset at different cycles.
