For two decades, the benefits of ESL and abstractions have been supposedly confined to engineers working on digital designs and to system architects. Analog and mixed-signal (AMS) design has largely remained a ‘circuit level’ activity. This article shows that tools exist that now also allow AMS engineers to exploit abstraction, and that can make all […]
System designs have traditionally achieved reliability through redundancy, even though this inevitably increases component count, logic size, system power and cost. The article describes the design separation feature in Altera software that seeks to address these as well as today’s conflicting needs for low power, small size and high functionality while maintaining high reliability and […]
Erich Marschner Accellera’s Unified Power Format (UPF) is in production use today, delivering the low-power system-on-chip (SoC) designs that are so much in demand. Building upon that success, IEEE Std 1801-2009 [UPF] offers additional features that address the challenges of low-power design and verification. These include more abstract specifications for power supplies, power states, and […]
USB offers many advantages for use on embedded systems, although software developers remain concerned about the additional complexity it can bring to an application. For example, software drivers for SPI, RS-232 and other traditional serial protocols typically involve little more than read and write routines, while USB software drivers can span thousands of lines, incorporating […]
The paper presents a fully parallel transistor-level full-chip circuit simulation tool with SPICE accuracy for general circuit designs. The proposed overlapping domain decomposition approach partitions the circuit into a linear subdomain and multiple nonlinear subdomains based on circuit nonlinearity and connectivity. A parallel iterative matrix solver is used to solve the linear domain while nonlinear […]
The Design Automation Conference (DAC) returns to San Francisco’s Moscone Center, July 26th-31st, and it is hoped that its proximity to Silicon Valley will see attendances hold up well even in tough times. However, the organizers are looking to more than just geography to guarantee continued interest in chip design’s main annual gathering. This 46th […]
The article describes a methodology that bridges the gap between SystemC transaction-level models (TLMs) that are used for architectural exploration and SystemC cycle-accurate models of hardware that typically follow much later in a design flow, after many sensitive decisions have been made. The behavior of the cycle-accurate models can be verified in the complete system […]
The article presents the context for the use of computation scaling (CS) to eke out more from existing lithography tools until next-generation techniques are finally introduced. It discusses the critical elements in the CS ecosystem developed by IBM and partners to overcome roadblocks to optical scaling that demand the use of non-traditional techniques for the […]
Circuit noise problems can originate from a variety of sources. By carefully examining attributes of the offending noise you can identify it’s source, thereby making noise reduction solutions become more apparent. There are three subcategories of noise problems: device, conducted and radiated noise. If an active or passive device is the major noise contributor, you […]
The article describes how a methodology based around scalable transaction level modeling (TLM) techniques can be used to enable software design to begin far earlier in a design fl ow and thus allow companies to bring designs to market faster, particularly in time-sensitive sectors. It is based on the creation of high-level hardware models that […]
