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

Adding Order And Structure To Verification


You can't improve what you can't measure, and when it comes to methodologies the notion of measurement becomes more difficult. Add in notions of the skills, capabilities and experience levels of individuals within an organization, which may affect their ability to adopt certain technologies, and it requires considerable attention. This is where concepts such as capability maturity models (CM... » read more

Clock Domain Crossings in the FPGA World


Clock domain crossing (CDC) issues cause significant amount of failures in ASIC and FPGA devices. As FPGA complexity and performance grows, the influence of CDC issues on design functionality grows even more. This paper outlines CDC issues and their solutions for FPGA designs. Various design techniques are presented together with real-life examples for Xilinx and Intel FPGA devices. More import... » read more

UPF-Aware Clock-Domain Crossing


Synopsys’ Namit Gupta talks with Semiconductor Engineering about low-power design techniques at the most advanced process nodes, including how to verify the impact of CDC on power at the register transfer level, how to avoid bugs caused by the post-RTL insertion of low-power devices such as isolation, retention and level shifters. https://youtu.be/HwRe9DHLfmg » read more

Raising The Bar On Flat CDC Verification With Hierarchical Data Models


By Ashish Hari, Aditya Vij, and Ping Yeung Traditionally, clock domain crossing (CDC) verification at the SoC level has relied on flat simulation runs. But flat CDC verification has run out of gas. Largely because of the increase in the number of asynchronous clocks in larger, faster, more complex designs. Flat CDC runs are too performance intensive, time-consuming, and result in high noise.... » read more

Comprehensive CDC Verification Using Advanced Hierarchical Data Models


In this paper, we describe the hierarchical data model (HDM), which is a performance efficient alternative to the traditional flat CDC verification flow. The HDM is equivalent to an abstract CDC model of the IP that captures the CDC intent of the block along with its integration rules. It is a generic data model that can be seamlessly re-used across releases and across designs wherever the IP i... » read more

The Week In Review: Design


Tools Synopsys revealed a power analysis solution for early SoC design as well as signoff-accurate power and reliability closure. PrimePower has reliability as a major focus, expanding power and reliability signoff and ECO closure capabilities from physical awareness to cell electromigration effects.
