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
