The Quest For A Better IP Integration Methodology


By Ed Sperling With the amount of IP in SoC designs now hitting an estimated 70% to 90%, companies are scrambling to figure out a way to more consistently integrate that IP and to test that it will work as expected. This is easier said than done, however, for a number of reasons: There are numerous types of IP, ranging from I/O to logic and memory. Not all IP is of equal quality. ... » read more

Fishing For Ideas In A Bigger Pond


By Ann Steffora Mutschler From networking to optical modeling to open source software platforms, EDA engineers are drawing from a variety of disciplines to develop tools for chip design, stretching the technology beyond its original intent. To this end, Synopsys acquired Optical Research Associates (ORA) last fall to add optical design and analysis to its portfolio. The acquisition allowed ... » read more

Keeping Up With Complexity


By Ed Sperling There are two schools of thought in designing complex SoCs. One says that increasing complexity requires a higher level of abstraction. The other says providing enough detail to get the design right is the only effective way to do it. There are staunch proponents of both approaches, but what has been missing are bridges to tie the higher level of abstraction to the more labo... » read more

Moore’s Law Revisited


By Ed Sperling The push to 20nm and beyond is creating some interesting gyrations in the EDA industry. While tools vendors continue to work on tools for the latest process nodes, they’re also taking some significant sidesteps. The first to publicly recognize a shift is under way was Cadence, which last year issued its EDA 360 manifesto. The strategy is to continue investing in existing to... » read more

Widening The Channels


By Ed Sperling Wide I/O—both as a specific memory standard and as a generic approach for on-chip networking—has been looked at for the past couple of chip generations as a way of improving SoC performance. Increasingly, it also is being used as a key strategy for reducing energy consumption. Wide I/O refers to a number of different approaches in on-chip networking, ranging from through-... » read more

Power Panel: IP And Other Key Issues For Future Development


By Ed Sperling Low-Power Engineering chaired a DesignCon panel of low-power experts with Bhanu Kapoor, president of Mimasic; Kesava Talupuru, DV engineer at MIPS; Prapanna Tiwari, CAE manager at Synopsys, and Rob Aitken, an ARM Fellow. What follows are excerpts of their presentations and the panel discussion that followed. Prapanna Tiwari: UPF and CPF are text files that capture the power i... » read more

The True Test Of IP Reuse


By Ann Steffora Mutschler Fewer and fewer systems and semiconductor companies are designing brand new processors from scratch. Instead, they leverage as much IP as possible in their designs, investing selectivity in areas where they can add significant value. The challenges are varied from low-power issues to process technology migrations. Generally, IP consumers are doing two levels of IP-... » read more

Memory, Bandwidth And SoC Performance


By Ann Steffora Mutschler High-end SoC architectures today can contain dozens of processing engines—multiple cores from MIPS and ARM, DSPs from Tensilica and CEVA, and even graphics processors. But with so many cores there also is a need for enormous amounts of memory, and that has been creating some unexpected design problems, In many cases so much memory is required for an SoC that some... » read more

The Growing Importance Of Subsystems


By Ed Sperling A growing reliance on third-party IP is beginning to expand well beyond just IP blocks and into full subsystems, opening significant growth opportunities for companies competing in this market as well as enormous business and technical challenges. The IP market is ripe for this kind of convergence. Complexity at advanced process nodes coupled with time-to-market demands has e... » read more

Stuck In The Corners


It’s common for semiconductor design teams to spend 60% to 70% of product development time on verification, which is why verification has bubbled to the top of the management chain as a concern. Executives worry about the predictability of their product development cycle because so much of it is dependent on successful execution of verification, the ability to achieve coverage closure and the... » read more
