Asynchronous & Synchronous Reset Design Techniques - …

Asynchronous & Synchronous ResetDesign Techniques - Part DeuxClifford E. CummingsDon MillsSteve GolsonSunburst Design , EngineeringTrilobyte paper will investigate the pros and cons of Synchronous and Asynchronous resets. It willthen look at usage of each type of Reset followed by recommendations for proper usage of Boston 2003 Asynchronous & Synchronous ResetRev Techniques - Part IntroductionThe topic of Reset Design is surprisingly complex and poorly emphasized. Engineering schoolsgenerally do an inadequate job of detailing the pitfalls of improper Reset Design . Based on ourindustry and consulting experience, we have compiled our current understanding of issuesrelated to Reset - Design and for this paper have added the expertise of our colleague Steve Golson,who has done some very innovative Reset Design work.

Synchronous resets are based on the premise that the reset signal will only affect or reset the state of the flip-flop on the active edge of a clock. The reset can be applied to the flip-flop as part of the combinational logic generating the d-input to the flip-flop. If this is the case, the
