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

Synthesizing Hardware From Software


The ability to automatically generate optimized hardware from software was one of the primary tenets of system-level design automation that was never fully achieved. The question now is whether that will ever happen, and whether it is just a matter of having the right technology or motivation to make it possible. While high-level synthesis (HLS) did come out of this work and has proven to be... » read more

What Is A Custom Processor?


Spurred by the latest cyclical development boom, the semiconductor industry is entering a new golden era of custom processors, but this time ‘custom processor’ means something different. A generation ago, every major semiconductor company had in-house processors: SuperH, PowerPC, V800, Alpha, MEP, Trimedia, etc., with some specializing more than others for particular domains. But industr... » read more

Blog Review: Aug. 21


Cadence's Paul McLellan considers the path to autonomous vehicles and the many barriers that stand in the way. Mentor's Colin Walls notes that the fundamental function of an RTOS is to give the developer control of time and points to some of the time oriented services that assist. Synopsys' Taylor Armerding points to ways the financial services industry could improve cybersecurity, from u... » read more

Week in Review: IoT, Security, Autos


Products/Services Arm released a survey of 650 industry representatives about eSIM and iSIM technology. Ninety percent of the respondents were aware of eSIM, while 43% were unaware of iSIM. Vincent Korstanje, vice president and general manager, Emerging Businesses at Arm, cites the leading three obstacles to large commercial deployments: Resistance from traditional stakeholders (69% of respond... » read more

Power Modeling Standard Released


Power is becoming a more important aspect of semiconductor design, but without an industry standard for power models, adoption is likely to be slow and fragmented. That is why Si2 and the IEEE decided to do something about it. Back in 2014, the IEEE expanded its interest in power standards with the creation of two new groups IEEE P2415 - Standard for Unified Hardware Abstraction and Layer fo... » read more

Blog Review: Aug. 14


Cadence's Paul McLellan digs into Mary Meeker's analysis of Internet trends, from growth of the Inernet as a whole to cyber attacks, online finance, and the gig economy. Synopsys' Taylor Armerding warns that the financial services industry is aware of cybersecurity threats, but isn't doing enough to protect its networks and data. Mentor's Colin Walls considers a few cases where writing in... » read more

Based in Germany, QTronic was founded in 2006 and makes a virtual ECU platform as well as a test automation solution with test case generator. Terms of the deal were not disclosed. VeriSilicon uncorked VIP9000, a highly scalable and programmable processor fo... » read more

Optimizing Power For Learning At The Edge


Learning on the edge is seen as one of the Holy Grails of machine learning, but today even the cloud is struggling to get computation done using reasonable amounts of power. Power is the great enabler—or limiter—of the technology, and the industry is beginning to respond. "Power is like an inverse pyramid problem," says Johannes Stahl, senior director of product marketing at Synopsys. "T... » read more
