Energy debugging – the next step in MCU software optimization

Knowing where your application is consuming resources is a crucial step in minimizing energy usage. The article describes a toolset developed by high-profile ARM-based microcontroller (MCU) start-up Energy Micro that helps to achieve this overarching goal within the context of a parallel move to 32bit MCU resolution.

Signoff-driven IC design

The demands of manufacturing closure at advanced process nodes make the traditional design-then-fix flow unmanageable. At 28nm and below, designers need a solution that can address manufacturing issues at any point in the design process, enabling a true correct-by-construction methodology. An effective solution must provide design-rule-check and design-for-manufacturing analysis using the actual foundry-approved signoff rules [...]

Device native debug and verification for FPGA

GateRocket's RocketDrive facilitates integration of an FPGA into an HDL simulator to provide a "native" execution of a design on its target FPGA device. The companion RocketVision tool provides software-debugging capabilities that directly identify and enable the rapid resolution of bugs. This article considers the use of these tools in a "device native" verification and [...]

Application-specific library subsetting

The limited cell count of standard cell libraries is restricting the performance that designs can achieve without resorting to expensive and time-consuming techniques. This article describes the addition of extended cell libraries and novel synthesis tools to a traditional RTL-to-GDSII flow in a new methodology that helps to overcome this performance brake. The technique is [...]

Winning the power and temperature battle with ESL exploration

The analysis of important power and temperature metrics for chip design is becoming increasingly inefficient when attempted at the register-transfer level. The article proposes the fundamentals of a system-level modeling strategy that will shrink design times, provide more opportunities for architectural exploration, and deliver significant power savings.

A UML design flow aimed at embedded systems

System Modeling Language (SysML) is a Unified Modeling Language (UML) profile that allows the creation of standard descriptions of a system. However, this profile is too generic to address embedded and real-time system design. The Modeling and Analysis for Real-Time and Embedded Systems (MARTE) UML profile attempts to fill this gap by providing elements from [...]
