10 Gb/s Design
Repeatably Fabricating Copper Channels for 10 Gb/s NRZ Signaling
Process variance during fabrication and environmental conditions of operation can have a significant impact on channel performance, making it crucial to understand the sources of variation and how they affect the channel's critical-to-function electrical parameters. A statistical approach for characterizing system performance and variation for 10 Gb/s channel designs.

Autorouting Completion and Quality
Can an autorouter compete with a top-notch designer? Competing with the experienced designer is simple enough: route it to 100%, maintain all the quality requirements, and do it in significantly less time. It's only software, right? An autorouter developer comes clean on completion rates and the role of the designer as artist.
