Hybrid Emulation


Semiconductor Engineering sat down to discuss the growing usage of hybrid verification approaches with Frank Schirrmeister, senior group director of product management & marketing for [getentity id="22032" e_name="Cadence"]; Russ Klein, program director for pre-silicon debug products at [getentity id="22017" e_name="Mentor, a Siemens Business"]; [getperson id="11027" comment="Phil Moorby"],... » read more

The Problem With Clocks


The synchronous digital design paradigm has enabled us to design circuits that are well controlled, but that is only true if the clocks themselves are well controlled. While overdesign techniques ensured that to be the case in early ASIC development, designs today cannot afford such luxuries. As we strive for lower power and higher operating frequencies, the clock has become a critical desig... » read more

What Is Portable Stimulus?


When [getentity id="22028" e_name="Accellera"] first formed the [getentity id="22863" comment="Portable Stimulus Working Group”] and gave it that name, I was highly concerned. I expressed my frustration that the name, while fitting with what most people thought [getkc id="10" kc_name="verification"] is about, does not reflect the true nature of the standard being worked on. In short, it is no... » read more

Embedded FPGAs Going Mainstream?


Systems on chip have been made with many processing variants ranging from general-purpose CPUs to DSPs, GPUs, and custom processors that are highly optimized for certain tasks. When none of these options provide the necessary performance or consumes too much power, custom hardware takes over. But there is one type of processing element that has rarely been used in a major SoC— the [gettech id... » read more

Bridging Hardware And Software


Methodology and reuse are two fairly standard concepts when it comes to semiconductor design, but they're viewed completely differently by hardware and software teams. It's a given that hardware and software have different goals and opinions about how best to do design. And while all agree that a single methodology can pay dividends in future chips, there is disagreement over who should shap... » read more

Software Driving More Hardware Designs


The influence of software engineers is growing inside of chip and systems companies, reversing a decades-old trend of matching the software to the fastest or most power-efficient hardware and raising as-yet unanswered questions about what will change in SoC design. The shift is particularly evident in chips developed for high-volume markets such as mobile phones and tablets. It's also happen... » read more

Tale Of Two HLS Viewpoints


The Design Automation Conference attracts several co-located conferences, symposiums and other such gathering of people, often on more specialized topics than would appeal to the general DAC attendees. Some of them are more research-focused, but one conference is somewhat strange in that it is about a subject that has transitioned to commercial tool development and yet still remains an active a... » read more

Design By Architect Or Committee?


Everything we do is based on a language. It doesn’t matter if we are talking about design, verification, specification, software or mask data. They all provide a way to communicate intent, and then there are engines that work on the intent to produce something else that is desirable, also based on a language. Over time, the EDA industry has built up a hierarchy of languages from the most deta... » read more
