What Happened To Portable Stimulus?


In June 2018, Accellera released the initial version of the Portable Test and Stimulus Standard (PSS), a new verification language that was slated to be the first new abstraction defined within EDA for a couple of decades. So what happened to it? Apart from a few updates at DVCon, there appears to be little talk about it today. However, the industry has its head down trying to make it work, ... » read more

RISC-V Driving New Verification Concepts


Semiconductor Engineering sat down to discuss gaps in tools and why new methodologies are needed for RISC-V processors, with Pete Hardee, group director for product management at Cadence; Mike Eftimakis, vice president for strategy and ecosystem at Codasip; Simon Davidmann, founder and CEO of Imperas Software; Sven Beyer, program manager for processor verification at Siemens EDA; Kiran Vittal, ... » read more

The Next Incarnation Of EDA


The EDA industry has incrementally addressed issues as they arise in the design of electronic systems, but is there about to be a disruption? Academia is certainly seeing that as a possibility, but not all of them see it happening for the same reason. The academic community questioned the future of EDA at the recent Design Automation Conference. Rather than EDA as we know it going away, they... » read more

Who Does Processor Validation?


Defining what a processor is, and what it is supposed to do, is not always as easy as it sounds. In fact, companies are struggling with the implications of hundreds of heterogenous processing elements crammed into a single chip or package. Companies have extensive verification methodologies, but not for validation. Verification is a process of ensuring that an implementation matches a specif... » read more

ASIC/IC Verification Trends With A Focus On Factors Of Silicon Success


At long last we come to the final installment of our four-part series presenting the findings of the Wilson Research Group Functional Verification 2020 study. In this article we discuss verification trends in IC/ASIC language and library adoption, low power management, and verification effectiveness. We then take a deeper dive into two somewhat surprising phenomena revealed in the data: the ... » read more

A Price To Be Paid


Ancient wisdom says you should be careful what you ask for, because you just might get it. This was certainly true many times during my career within EDA, and I am sure it is still happening today. Sometimes the outcome was not what was wanted, or the price was higher than expected. As an example, consider VHDL, the language that was meant to correct the problems of Verilog. One of the probl... » read more

Clarifying Language/Methodology Confusion


Engineers working on modern, large FPGA designs face multiple challenges: changing languages, methodologies and tools implementing them. The fact that many designs now contain both hardware and software only add to the confusion. This document tries to clarify the situation. Click here to read more. » read more

The Evolution Of High-Level Synthesis


High-level synthesis is getting yet another chance to shine, this time from new markets and new technology nodes. But it's still unclear how fully this technology will be used. Despite gains, it remains unlikely to replace the incumbent RTL design methodology for most of the chip, as originally expected. Seen as the foundational technology for the next generation of EDA companies around the ... » read more

Universal Verification Methodology Running Out Of Steam


For the past decade or so, the Universal Verification Methodology (UVM) has been the de facto verification methodology supported by the entire EDA industry. But as chips become more heterogeneous, more complex, and significantly larger, UVM is running out of steam. Consensus is building that some fundamental changes are required, moving tools up a level of abstraction and making them more ag... » 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
