WebThe strongly fail-safe property is achieved by means of concurrent checking techniques. The interest of these interfaces is that they can be implemented in VLSI, while the conventional fail-safe interfaces require using discrete components. A formal theory of fail-safe systems is developed to guide the implementation of the new solutions. WebPhysical Design Q&A. Q191. What is a zero-bit retention flop? All retention flops need isolation on its clock pin and reset pin. These isolations can be implemented either as a part of the retention flop or we can have a separate isolation cell connected to the CK/RST pin. The advantage with the first implementation is that it reduces the ...
