Know Your Own Power, Early And Accurately

By Taruna Reddy and Vin Liao Chip designers have always had to balance timing and area. Everyone wants a design as fast as possible and as compact as possible, but these two goals are usually in conflict. For the last couple of decades, minimal power consumption has been a third goal, often of equal importance. Some of the biggest drivers for the semiconductor industry are battery operated p... » read more

The Week In Review: Design

Tools Real Intent launched Verix SimFix, an intent-driven verification solution for gate-level simulation (GLS) of digital designs designed to eliminate X-pessimism. SimFix uses mathematical methods to identify conditions under which pessimism can occur, and to determine the correct value when those conditions occur. It then generates files to use in simulation that detect and correct pessimis... » read more

Gate-Level Simulation Methodology

The increase in design sizes and the complexity of timing checks at 40nm technology nodes and below is responsible for longer run times, high memory requirements, and the need for a growing set of gate-level simulation (GLS) applications including design for test (DFT) and low- power considerations. As a result, in order to complete the verification requirements on time, it becomes extr... » read more

Know What To Look For

With the number of power domains exploding in today’s ICs, it’s extremely difficult to include all different modes of complexity in the verification. “The problem was already challenging enough,” observed Mark Baker, director of product marketing at Atrenta. “Just looking at where SoC design was going was a collection of various IPs, the different communication protocols, the bus ... » read more

Aren’t We Beyond That?

The latest and greatest technologies always get the most attention because they are new and fresh, but gate-level simulation—a long-time workhorse tool—is seeing a small comeback with designers as of late. According to Cadence’s Pete Hardee, even though the industry is spending a lot of time looking ahead to architectural-level power modeling and virtual prototyping, the need for detai... » read more
