CDC Methodology For Fast-To-Slow Clocks


CDC checking of any asynchronous clock domain crossing requires that the data path and the control path be identified and that the receive clock domain data flow is controlled by a multiplexer with a select line that is fed by a correctly synchronized control line.  Meridian CDC identifies all the data and associated control paths in a design and will ensure that the control signals passing fr... » read more

Blog Review: Oct. 16


Cadence’s Richard Goering follows Si2’s move into SPICE modeling following the acquisition of the Compact Model Council. Combining standards groups is a growing trend these days. Mentor’s Colin Walls points to the demise of reset buttons. You can always trip a circuit breaker, and usually turn off a device by pulling out the battery, but a reset button is simpler. Where did they go? ... » read more

Blog Review: Oct. 9


By Ed Sperling Mentor’s Simon Favre raises an interesting question: Why are 450mm wafers and EUV lithography related? The answer may surprise you. In his second broadcast, Cadence’s Brian Fuller interviews Gary Smith about where EDA will grow, why industry consolidation is a myth and why there is a dearth of reliable information about the electronics industry. Synopsys’ Mick Posner... » read more

Executive Briefing: Prakash Narain


Real Intent CEO Prakash Narain talks with System-Level Design about where are the pain points in verification; different types of signoff; the impact of third-party IP, and can the tools industry keep up with the rising complexity in semiconductor design. [youtube vid=C25VMRDXGAQ] » read more

The New Verification Landscape


By Ann Steffora Mutschler Verification technologies and tools have never been more sophisticated. But putting together a methodology is more than just putting tools together. It starts with trying to get a handle on the complexity, knowing what to test, how to test and when. “UVM was standardized and people have been working to adopt that which has been generally a positive,” said Steve Ba... » read more

Best-In-Class Tools Lead To Best-In-Class Design?


Today’s systems on chip (SoC) are deeply complex in new ways. A dozen or so years ago, a state-of-the-art processor such as the Intel Pentium 4 used 42 million transistors, was built on a 180nm process and relied upon discrete chips to handle its system interfaces. Jump forward, and the Intel Xeon Phi processor that Intel introduced in 2012 uses 5 billion transistors and is built on a 22nm pr... » read more

The Week In Review: June 21


By Ed Sperling Mentor Graphics rolled out emulation-ready verification IP for MIPI camera and display-based protocols. The VIP enables stimuli generated by UVM and SystemC-based environments and applies them to a design under test (DUT) running in the emulator. Synopsys introduced a tool for implementing and verifying functional engineering change orders, including matching, visualization ... » read more

Formal Verification Comes Of Age


By Ann Steffora Mutschler Formal verification technology, also known as formal property checking, has been in existence since the early 1990s. Still, it’s only in the past five years that it has made big strides in the last five years in terms of the capacity of the technology to handle bigger pieces of a design, leveraging advancements in computing as well as improvements to the algor... » read more

The X Factor


By Ed Sperling The number of unknowns is growing in every segment of SoC design all the way through manufacturing, raising the stakes between reliability and the tradeoffs necessary to meet market windows. Tools are available to deal with some of these unknowns, or X’s, but certainly not all of them. Moreover, no single tool can handle all unknowns, some of which can build upon other unkn... » read more

Does SoC Signoff Mean More Than RTL?


As the cost of failure continues to rise, SoC engineers see the growing importance of ensuring their work is as correct as possible as soon as possible in the design process. They cannot afford to carry errors forward from one stage to the next, where their impact grows while their causes become more obscured. This requirement is driving the shift in design exploration and handoff to the reg... » read more
