The ‘state-of-the-art’ solution for wireless transceiver RF ICs is single chip CMOS, integrating digital, analog, and RF blocks on a single chip. The architectures involved require new and challenging approaches to verification. To understand these, we first need to look back at the history of the transceiver architectures used for wireless mobile phone implementations during […]
The verification of digital sub-systems is based on advanced techniques such as constraints capture, randomized or pseudo-randomized stimuli generation and results collection with functional coverage evaluation. The use of manually verified hand-coded analog block models within a digital verification environment has so far been sufficient. However, the move to greater levels of integration, shrinking process […]
Wilf Corrigan ‘Epitaxy innovator’, ‘ASIC champion’, ‘SIA founder’. Those are a few of the descriptions you could apply to Wilf Corrigan. Another, until May, was ‘Last of the Pioneers’ – but then, after 46 years of involvement with major chip companies, Corrigan stepped down as chairman of LSI Logic, the company he set up with […]
SystemC [1] is rapidly becoming the language of choice for ESL-centric design methodologies. It is set to become the framework for higher-level flows above today’s RTL, and has three key components: modeling, synthesis and verification. High-level modeling particularly demonstrates the language’s versatility and advantages. Strong progress is also being made in higher-level synthesis. However, our […]
Processor program storage today Most of the microcontrollers currently on the market store program code in one of three ways: in ROM on the same chip as the MCU; in embedded flash memory on the same chip as the MCU; or as external flash memory whose contents are downloaded to the MCU. Each of these […]
Analyses made by semiconductor manufacturers have demonstrated that maintaining pattern fidelity is critical, and that this task faces increasing limitations at the 65nm process node and below. At these technology nodes, even the most advanced resolution enhancement technologies (RET) have a difficult time with certain layout topologies. When the impact of this is observed across […]
Design-for-manufacturability (DFM) has become pervasive and there is general agreement on the need to apply DFM at multiple stages of the design cycle. DFM techniques at the relatively mature 0.13um technology node entail well known enhancements such as contact and via redundancy, line-ends and borders, and wire spreading. Mature technology nodes achieve product yields which, […]
Kerry Bernstein When Kerry Bernstein, a 28-year IBM veteran, was first drafted to work on Big Blue’s development of 3D semiconductors, he admits he was a skeptic. “At first, I think I felt as though I’d got dragged into this program. I thought it wasn’t going anywhere. I thought it was going to go anywhere. […]
Productivity levels for hardware design, specification, simulation and validation have been raised by the formal approval of IEEE 1800 SystemVerilog as an industry standard. Evolved from the Verilog hardware description language, SystemVerilog is now the language of choice for developing verification and design intellectual property (IP). As a result, EDA companies are progressing rapidly in […]
Why are more chips late to market and cost three times more to design at 90-nanometer (nm) than at 130nm? Today’s ASSPs and ASICs are huge, approaching one billion transistors, with clock speeds exceeding 1-GHz. Engineers struggle to manage the complexity of devices that achieve these levels of performance and size. A natural reaction to […]
