Power Aware Intent And Structural Verification Of Low-Power Designs


Power aware static verification, more popularly known as PA-Static checks, is performed on designs that adopt certain power dissipation reduction techniques through the power intent or [gettech id="31044" t_name="UPF"]. The term static originates from verification tools and methodologies that applies a set of pre-defined power aware (PA) or multi-voltage (MV) rules based on the power requiremen... » read more

IP And Power


[getkc id="108" kc_name="Power"] is quickly becoming a major differentiator for products, regardless of whether they are connected to a wall outlet or dependent on a battery. At the same time, increasing amounts of a chips content comes from third-party [getkc id="43" kc_name="IP"]. So how do system designers ensure that the complete system has an optimal power profile, and what can they do to ... » read more

Artifacts Of Custom Checkers In Questa Power-Aware Dynamic Simulation


UPF provides a powerful mechanism to define a custom PA checker or assertion and provides a layer to completely separate it from design code. This is done by embedding the binding of the design and checker within the UPF file through the bind_checker command and its options. As a result, it provides a consolidated verification mechanism and allows Questa PA-SIM to access all instances of a targ... » read more

Power Modeling and Analysis


Semiconductor Engineering sat down to discuss power modeling and analysis with [getperson id="11489" p_name="Drew Wingard"], chief technology officer at [getentity id="22605" e_name="Sonics"]; [getperson id="11763" comment="Tobias Bjerregaard"], chief executive officer for [getentity id="22908" e_name="Teklatech"]; Vic Kulkarni, vice president and chief strategy officer at [getentity id="22021"... » read more

UPF Power Domains And Boundaries


The Universal Power Format (UPF) plays a central role in mitigating dynamic and static power in the battle for low-power in advanced process technology. A higher process node is definitely attractive as more functionality integration is possible in a smaller die area at a lower cost. However, in reality, this comes at the cost of exponentially increasing leakage power. This is because the minim... » read more

Dealing With System-Level Power


Analyzing and managing power at the system level is becoming more difficult and more important—and slow to catch on. There are several reasons for this. First, design automation tools have lagged behind an understanding of what needs to be done. Second, modeling languages and standards are still in flux, and what exists today is considered inadequate. And third, while system-level power ha... » read more

Verification Unification


Semiconductor Engineering brought together industry luminaries to initiate the discussion about the role that formal technologies will play with the recently released early adopter's draft of Portable Stimulus and how it may help to bring the two execution technologies closer together. Participating in this roundtable are Joe Hupcey, verification product technologist for [getentity id="22017" e... » read more

Libraries: Standardization and Requirements For Power-Aware Dynamic Simulation


INTRODUCTION Multivoltage (MV) based power-aware (PA) design verification and implementation methodologies requires special power management attributes in libraries for standard, MV and Macro cells for two distinctive reason. The first aspect is to provide power and ground (also bias) supply or PG-pin information, which is mandatory for PA verification. The second reason is to provide a distin... » read more

Closing The Loop On Power Optimization


[getkc id="108" kc_name="Power"] has become a significant limiter for the capabilities of a chip at finer geometries, and making sure that performance is maximized for a given amount of power is becoming a critical design issue. But that is easier said than done, and the tools and methodologies to overcome the limitations of power are still in the early definition stages. The problem spans a... » read more
