Constraint-Based Verification Of Clock Domain Crossings


There are many measures of the ever-growing size and complexity of semiconductor devices: die area, transistor count, gate count, size of memories, amount of parallel processing and more. All these factors mean more time spent in design, but they also have a major impact on verification. Since virtually all industry studies show verification time and effort growing faster than design, this impa... » read more

Manufacturing Bits: March 9


Finding cures for coronavirus The Department of Energy’s Oak Ridge National Laboratory (ORNL) is using the world’s most powerful supercomputer to identify drug compounds and cures for the coronavirus.

An Industry Under Siege


The coronavirus is taking a big toll on the semiconductor industry's unquenchable thirst for new information. The longer it lasts, the more the industry will have to resort to technology — some new, some old — to continue moving forward. Over the past couple weeks, conferences and trade shows have been postponed or outright canceled. Synopsys, Cadence and Intel pulled out of DVCon at the... » read more

Fusing Implementation And Verification


Susantha Wijesekara, senior application engineer at Synopsys, drills down into how to re-use Tcl scripts for static verification, what needs to be done with those scripts to make that possible, why that is critical to “shift left,” and how that approach saves time, money, and improves quality. » read more

Dynamic CDC Jitter For Clock Domain Crossing (CDC) Signoff


By Himanshu Bhatt and Paras Mal Jain Detecting and debugging deep sequential CDC convergences using structural CDC verification is extremely difficult since doing a flat analysis on large designs has capacity related challenges, and even if verification tools can complete the analysis, it becomes a nightmare to debug the violations with complex sequential logic. Thus arises the need for dyna... » read more

Shift Left Power-Aware Static Verification


Next-generation SoCs with advanced graphics, computing, machine learning (ML) and artificial intelligence (AI) capabilities are posing new unseen challenges in Low Power Verification. These techniques can introduce critical bugs into a design, especially when the power-management infrastructure interacts with signals that cross clock or reset domains. This can create additional clock-domain cro... » read more

Clock Domain Crossing Signoff Through Static-Formal-Simulation


By Sudeep Mondal and Sean O'Donohue Clocking issues are one of the most common reasons for costly design re-spins. This has been the driving factor in the ever-increasing demand for Clock Domain Crossing (CDC) analysis tools. Today, the majority of IP and SoC teams are focusing on “Structural CDC” analysis, which is important but not sufficient. Structural CDC analysis ensures that the d... » read more

Signoff-Compatible CDC


Tanveer Singh, senior staff consulting applications engineer at Synopsys, explains why netlist clock domain crossing is now an essential complement to RTL CDC, why CDC issues are worse at advanced nodes and in AI chips, and why dealing with CDC effectively is becoming a competitive requirement for performance and low power. » read more

Week In Review: Design, Low Power


CEVA acquired the Hillcrest Labs business from InterDigital. Hillcrest Labs supplies software and components for sensor processing in consumer and IoT devices. Hillcrest Labs' MotionEngine sensor processing software already runs on CEVA DSPs (as well as ARM and RISC-V cores) and enables high accuracy 6-axis and 9-axis sensor fusion, dynamic sensor calibration, and application specific features ... » read more

FPGA And System Designs Get To Market Faster Leveraging ASIC-Proven Analysis Tools


Increasing power constraints have resulted in finer-grained partitioning of designs into functional domains that can have clocks disabled or, more drastically, are powered down entirely. Systems are required to adaptively manage clocks to minimize switching power. Performance and area constraints have led to the abandonment of more conservative practices in favor of more aggressive designs; ... » read more
