A Specification-Driven Methodology For The Design And Verification Of Reset Domain Crossing Logic


Reset architectures have increased in complexity along with SoC designs. Sadly, traditional reset design and verification techniques have not evolved to address this increase in complexity. In order to avoid ad-hoc reset methods, this paper presents a three-step specification-driven methodology that provides a requirements-based approach for reset domain crossing design and verification.

Resetting Serial Memory When A System Failure Occurs


Stability is an important consideration in embedded design, but electronic systems can suffer malfunctions triggered by a myriad of root causes. These include poor signal integrity, power spikes, software errors, and erroneous user interaction, just to name a few. These anomalies, in turn, can lead to inconsistent system operation or can even cause the system to hang. Although the list of po... » read more

Resets And Reset Domain Crossings In ASIC And FPGA Designs


This white paper explains Reset-related ASIC and FPGA design issues as well as outlines commonly-used design techniques leading to safe reset implementations. It goes on to explain about Reset Domain Crossing effects and methods to mitigate their influence on design. LINT tools provide valuable help for designers in Resets and Reset Domain Crossings verification. To download this paper, clic... » read more

Respecting Reset


Resets are a necessary part of all synchronous designs because they allow them to be brought into a known state. However, such a simple process can lead to many problems within an [getkc id="81" kc_name="SoC"]. No longer can reset be considered a simple operation when power initially is applied to a circuit. Instead, the design of reset has many implications on cost, area and routability, a... » read more

The X Factor


By Ed Sperling The number of unknowns is growing in every segment of SoC design all the way through manufacturing, raising the stakes between reliability and the tradeoffs necessary to meet market windows. Tools are available to deal with some of these unknowns, or X’s, but certainly not all of them. Moreover, no single tool can handle all unknowns, some of which can build upon other unkn... » read more
