Can Big Data Help Coverage Closure?


Semiconductor designs are a combination of very large numbers and very small numbers. There is a large numbers of transistors at very small sizes, and databases are often large. The chip industry has been looking at [getkc id="305" kc_name="machine learning"] to effectively manage some of this data, but so far datasets have not been properly tagged across the industry and there is a reluctan... » read more

Merging Verification With Validation


Verification and validation are two important steps in the creations of electronic systems and over time their roles, but how they play together is changing. In fact, today we are seeing a major opportunity for rethinking this aspect of the flow, which could mean the end of them as separate tasks for many of the chips being created. As with many things in this industry, however, squeezing it... » read more

The Week In Review: Design


Tools & IP Pro Design launched three new proFPGA Zynq UltraScale+ FPGA modules for SoC and IP prototyping. The modules combine FPGA logic with quad-core ARM Cortex-A53 and dual-core ARM Cortex-R5 processors and on-board interfaces. The modules offer a total of up to 5 extension sites with 531 standard I/Os and 16 multi-gigabit transceivers (MGTs). The board allows a maximum point-to-point ... » read more

Which Verification Engine?


Semiconductor Engineering sat down to discuss the state of verification with Jean-Marie Brunet, senior director of marketing for emulation at [getentity id="22017" e_name="Mentor, a Siemens Business"]; Frank Schirrmeister, senior group director for product management at [getentity id="22032" e_name="Cadence"]; Dave Kelf, vice president of marketing at [getentity id="22395" e_name="OneSpin Solut... » read more

The Trouble With Models


Models are becoming more difficult to develop, integrate and utilize effectively at 10/7nm and beyond as design complexity, process variation and physical effects add to the number of variables that need to be taken into account. Modeling is a way of abstracting the complexity in various parts of the semiconductor design, and there can be dozens of models required for complex SoCs. Some are ... » read more

Prototypes Proliferate


Hardware prototyping and [getkc id="30" kc_name="emulation"] have been two sides of the same coin ever since the [gettech id="31071" comment="FPGA"] became a commercial success. Early emulators were all built from FPGAs, and most were used in-circuit, much like prototypes are today. More recently, emulation has become a major piece of the [getkc id="10" kc_name="verification"] flow, to the poin... » read more

System Coverage Undefined


When is a design ready to be taped out? That has been one of the toughest questions to confront every design team, and it's the one verification engineers lose sleep over. Exhaustive [getkc id="56" kc_name="coverage"] has not been possible since the 1980s. Several metrics and methodologies have been defined to help answer the question and to raise confidence that important aspects of a block... » read more

Making Software Development Equivalent For Models And Boards


Selected Cortex-M processors include the instruction trace microcell (ITM) to help understand system behavior. Although it can provide other types of trace, the ITM is commonly associated with printf() output and event tracing from applications and operating systems. Historically, Fast Model systems have used semihosting or UART models to provide character and file I/O when running software on ... » read more

Verification’s Breaking Points


Verification efficiency and speed can vary significantly from one design to the next, and that variability is rising alongside growing design complexity. The result is a new level of unpredictability about how much it will cost to complete the verification process, whether it will meet narrow market windows, and whether quality will be traded off to get a chip out on time in the hopes that it c... » read more
