Bring decaps under control with automated analysis
Better PCB design using the fabricator’s view
Concurrent design: one team, one virtual location
Overcoming increasing PCB complexity with automation
Make simulation your friend
The earlier in a design cycle a decision can be made, the shorter the development time and the lower the development cost. This is probably the most important product development principle, and is especially true when interconnects are not transparent and signal or power integrity could be holding back performance. You must find, fix and […]
Automating sawtooth tuning for differential pairs
Length matching within a differential pair can be one of the more tedious tasks facing a PCB designer. This article describes how a team at communications and consumer electronics semiconductor company Broadcom overcame this by using the automation options available within their design tools. While the article describes automation tailored to a specific task, the […]
Change you’d better believe in
This special edition of EDA Tech Forum Journal concentrates on PCB design. It’s an exciting area technologically right now, and we hope that the editorial content reflects that. One theme that kept emerging was that many of the contributors believe their discipline is at some sort of tipping point. And these changes don’t just come […]
Defying the downturn
Emerging technologies and markets could spur PCB tool growth despite economic concerns, says Mary Ann Olsson The worldwide PCB EDA software market maintained fairly stable 3.4% growth in 2007. Sales reached $532.5M, from $514.7M in 2006. The projected growth rate for PCB software in 2008 is 2.3%, bringing sales to $544.7M (Figure 1). One key […]
The impact of HDI and microvias on PCB design
What impact do HDI via structures have on PCB design metrics? Andy Kowalewski describes a recent experiment. A PCB’s density has traditionally been seen as a function of the trace and space geometry and the number of signal layers. Emerging technologies such as microvias and buildup fabrication may force us to rethink this formula. In […]
