Three Steps To Low Power Coverage Closure
By Awashesh Kumar - 18 Jun, 2018 - Comments: 0

By Awashesh Kumar and Madhur Bhargava Low-power design and verification is becoming more complex. Yet it is critical that all power elements are verified, and it is even more important to verify the complex interactions between these elements at a high abstraction level. However, power-aware coverage closure is difficult to attain and complex by nature. Existing low-power coverage methodo... » read more

Power-Aware Intent And Structural Verification Of Low-Power Designs
By Progyna Khondkar - 12 Apr, 2018 - Comments: 0

In Part 1 of this series on power aware (PA) verification, we examined the foundations and verification features of PA static checks. In Part 2, we will discuss the features of the static verification library and describe best static verification practices. Library for Static Verifications Cell-level and pin-level attributes from Liberty are mandatorily required for accurate PA-Static verif... » read more

Power Aware Intent And Structural Verification Of Low-Power Designs
By Progyna Khondkar - 08 Mar, 2018 - Comments: 3

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

Get To Know The Gate-Level Power Aware Simulation
By Progyna Khondkar - 28 Sep, 2017 - Comments: 1

The post-synthesis gate-level netlist (GL-netlist) based PA simulation input requirements are mostly the same as RTL simulation. However, the design under verification here is the GL-netlist from synthesis, so logic gates from standard, MV and Macro cell Liberty libraries are already inserted or instantiated in the design. Hence power aware simulation (PA-SIM) at post-synthesis also requires Li... » read more

Libraries: Standardization and Requirements For Power-Aware Dynamic Simulation
By Progyna Khondkar - 08 Jun, 2017 - Comments: 0

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

Managing Power Without Impacting Design Intent
By Christine Young - 08 Sep, 2016 - Comments: 0

The good news is that there are many techniques available to optimize power in your design. The not-so-good news? Many of these power management techniques also create new complexities in the physical and functional behavior of electronic designs. Fortunately, there’s more good news: implementing a power-aware verification methodology can help you verify power optimization without detracti... » read more

Power Verification Now Required
By Ann Mutschler - 17 Jun, 2015 - Comments: 0

Today’s verification tasks may seem daunting — and much of it is — but all of it is absolutely necessary to make sure chips operate properly with a larger system. Throw power into the mix and the challenges mount. The good news is that there is no shortage of tools and methodologies to help with these tasks. The bad news is that even the best tools won’t make the challenges disappear... » read more

Why So Formal?
By Bhanu Kapoor - 21 May, 2010 - Comments: 0

By Bhanu Kapoor Let’s take a look at the types of power management verification issues that are most suited for formal verification and how formal techniques complement dynamic simulation-based verification in some of the challenging tasks associated with validating SoC power management architectures. There are three main categories of formal tools in use today: Equivalence Checkers, Asse... » read more
