MCMM

Mixed-signal chip designer Semtech on using Lynx Design System to manage multi-corner multi-mode sign-off when you've got 306 scenarios to check.

The number of scenarios needed for MCMM timing analysis has skyrocketed. IC implementation calls for a concurrent approach to deal with the issue.

Extracting finFET parasitics means a shift to 3D models, field solvers for greater accuracy, and MCMM techniques.

Using hierarchy and improved constraints management to accelerate static timing analysis at 20nm and below.

STMicroelectronics in Greater Noida, India recently completed an Omega2 set-top-box decoder IC targeted at HDTV markets. This article discusses how ST used Mentor Graphics’ Olympus-SoC software to address the closure challenges presented by a very large design. It describes how the design team used the tool suite’s chip assembly, concurrent multi-corner multi-mode (MCMM) analysis and [...]

The architectures that underpin today’s traditional place-and-route tools are showing their age, largely because their static timing analysis engines cannot handle more than two mode/corner scenarios. Thus limited, the software struggles to effectively implement low-power design techniques beyond such established concepts as clock gating and multiple threshold voltages. Designers run into difficulties when trying to […]

Signal integrity (SI) is an ever-growing problem as more interconnect effects and fast clocks increase the chances of crosstalk noise and glitches as well as unexpected signal delays. There has been a significant increase in SI-related timing violations due to the increasing influence of lateral wire capacitance in designs at 65 and 45nm. A fast-increasing […]

Concurrent multi-corner, multi-mode analysis and optimization is becoming increasingly necessary for sub-65nm designs. Traditional P&R tools force the designers to pick one or two mode corner scenarios due to inherent architectural limitations. As an example of the problem, a cellphone chip typically needs to be designed for 20 mode/corners scenarios. In the absence of a […]
