Companies and mask shops already have plans and policies to secure the storage and transmission of sensitive layout VLSI data. These include confidentiality and non-disclosure agreements, and encryption. However, traditional VLSI file formats such as GDSII never popularized the type of constructs that facilitate intellectual property (IP) protection. The OASIS format does have these constructs. […]
Considering how complexity has grown over the last 20 years, it is amazing how few dramatic shifts in the design and verification methodology have occurred. When they do happen — mylar to layout tools, gates to RTL, hand-crafted test vectors to testbench automation — they make our work as engineers easier and enable us to […]
If you want to get a clear idea of just what is taxing engineers at any given time, you can do a lot worse than following the trends that emerge before each annual Design Automation Conference (DAC). “And this year, it is pretty clear that there are three things on everyone’s mind: power, system-level design […]
Once upon a time, placing even the smallest question mark next to Moore’s Law was seen as something beyond heresy. Today, more and more people are voicing such thoughts in the mainstream. One of the most senior figures speaking out is Bernard Meyerson, vice president and chief technologist of IBM’s Systems & Technology Group. The […]
Major yield-Inhibiting Issues At each successive process node, additional defect mechanisms appear and hinder the ability to achieve desired yield (Figure 1). The trend toward declining yields has led to a resurgence in the application of design for manufacturing (DFM) methodologies.Much of this reinvigorated effort relies heavily on a new breed of tools and technologies. […]
Semiconductor devices are being fabricated with features that are less than half the wavelength of the available lithography exposure tools. Increasing circuit density has improved the complexity and performance of ICs but also led to serious patterning proximity effects. These effects make the chips almost impossible to fabricate without optical proximity correction (OPC) technology. Thus, […]
Design teams are becoming increasingly concerned at the growing disparity between the capacity of silicon in the latest processes and the design and verification capabilities of simulation tools. A number of trends are now converging to enable a step function increase in verification to complement and extend the debug and verification capabilities of HDL simulators. […]
The efficient management and synchronization of design data is now a necessity and no longer something that is a ‘nice-to-have’. Design complexity continues to increase with one result being that development spreads across several groups (often in different places). A project may also have several thousands design files generated by various tools from different vendors […]
The network-on-chip (NoC) design paradigm is seen as a way of enabling the integration of an exceedingly high number of computational and storage blocks in a single chip. But its adoption and practical implementation face important and unsolved issues related to design methodologies, test strategies, and dedicated CAD tools. The System-on-a-Chip Research Lab at the […]
If one thing has become clear as process geometries have gone below one micron, it is that the traditional development model is broken. It seems only recently that companies were talking about adopting a greater ‘customer focus’, but even the linear sequence of first, finding out what the client wants; second, getting your designers to […]
