Programmable logic blends 'soft IP' News & Analysis 3/30/1999 Post a comment Until fairly recently, the ASIC and programmable-logic industries have been characterized by continual introductions of ever-larger "blank slate" devices. In other words, vendors placed the burden of system-level design on the shoulders of their customers. However, traditional development tools and methods fall short of the levels of complexity needed for the system-on-chip (SOC) applications targeted for these devices. As a result, designers have been forced to make difficult choices between lo
Single-chip systems leap technology barriers News & Analysis 3/30/1999 Post a comment While advances in semiconductor fabrication technology have always been roughly measured in circuit density, the current stir over system-on-a-chip (SOC) capability marks a significant change in industry metrics. Rather than asking how many devices can be crowded onto a single piece of silicon, semiconductor experts are now turning to the question of how many different circuit types can be merged. The vision-blending a palette of technologies in a single fab run-could potentially boost the usefu
