Physical Lint: Physical Quality Metrics For Your RTL

Why Analyze Physical Metrics at RTL? The quality of the logic structures generated from RTL has a direct impact on the number of design iterations required to close a design. Additionally, the quality of logic structures generated from RTL has a direct impact on design utilization. These trends are illustrated in Figure 1. Essentially, improving the quality of the logic structures in a d... » read more

Power Exploration: MLB World Series, Bumgarner, And Box Scores

The San Francisco Giants are fresh off their third Major League Baseball (MLB) World Series win in the last 5 years. That's notable in itself, but then consider Madison Bumgarner, the starting pitcher for the Giants who was named the 2014 World Series MVP. Bumgarner finished this year’s series with a 2-0 record, one five-inning save (game seven) and 0.43 ERA in three appearances, highlighting... » read more

Constraints Ubiquity: Impact On Managing Design Closure?

By Mark Baker and Ravindra Aneja Maintaining completeness, correctness and consistency of design constraints is a challenge that is pervasive in the design flow. Multiple transformations, or touch points (as illustrated in the diagram below), exist during the design implementation stages. Additionally, there are parallel stages involving IP development and handoff resulting in SoC integration ... » read more

Does EDA Consider RTL Power Optimization As Job Done?

The “Power Buzz” leading into this year’s Design Automation Conference was around System Level Power Architecture and Optimization—some would say the natural progression of EDA towards the next big customer design challenge. This does beg the question of whether EDA considers RTL Power Optimization a mature solution. All products or solutions progress through various stages of maturity,... » read more

Can RTL Power Estimation Accuracy Be Improved?

The power targets for today’s complex SoC designs force design teams to address power optimization earlier and more effectively than ever before. In recent years, design teams have migrated to RTL power estimation solutions to identify areas of potential power savings to be used in early design tradeoffs. RTL power estimation accuracy at 15% to 20% to gate-level power numbers is deemed accept... » read more

Power Verification in Sochi?

An estimated 3 billion viewers watched in wonder at the high tech artistry of the opening ceremonies of the $50 billion Sochi Winter Olympics. As many viewers later learned, these events are often not without glitches. The after buzz was all about the Olympic ring failure. When only four of the five snowflakes transitioned into rings, the broadcasters resorted to rehearsal footage attempting to... » read more

Power Resolutions For 2014

As the ball dropped at midnight in New York’s Time Square, signifying the beginning of 2014, many had already decided on their resolutions for the New Year. Others decide during the first few days of the New Year. Undoubtedly, consideration involves common resolutions that we fall back on year after year. Individuals might think about health, losing weight and becoming more fit. Others think ... » read more

Door Busters In Low Power Optimization

The holiday season is upon us, notably a shortened gift buying season at that, which for some only adds to the anxiety felt at this time of year. Many shoppers are out there searching for a door buster deal on that “hot item,” but choices must be made on where to allocate one’s time. Should one stop with the door buster deals or take the time to look further for more practical or traditio... » read more
