What is power Aware verification?
What is power Aware verification?
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 Unified Power Format.
What is low power verification?
Low power static verification checks help to verify correct implementation of low power design techniques using formal techniques (versus simulation) early in the design process. This would ensure that no low power cell is missed between two voltage or power domains.
What is UPF simulation?
The Unified Power Format (UPF) is a published IEEE standard and developed by members of Accellera. It is intended to ease the job of specifying, simulating and verifying IC designs that have a number of power states and power islands. The most recent officially published version is IEEE 1801-2013.
What is VCS NLP?
VCS® NLP natively performs power aware simulation with a complete understanding of the UPF-defined power network, at RTL prior to implementation.
What is power aware RTL?
Power intent awareness is mandatory for early estimating power with multiple voltage islands and power islands. RTL power tools must consider switch off conditions as well as operating voltages of different islands for accurate power estimation.
What is power state table in UPF?
The power/supply sets state of the power objects are the entry values in the power state table. In UPF 2.0, power state definitions using add_power_state commands are hierarchical in nature. That is, the power state of a system is dependent on power state of its constituent IPs (represented as power domains).
What is Mvsim?
MVSIM, a core component of Synopsys’ Eclypse™ Low Power Solution, is production-proven and works at the RTL and gate levels. MVSIM addresses complex low power verification challenges and enables customers to achieve their high-quality goals while meeting time-to-market constraints.
What is VCLP in VLSI?
VC LP validates the design in its entirety and checks the critical signal networks in the design for the various power modes. These checks help find connectivity related bugs, which would cause functional issues very early in the design cycle.
What UPF contains?
The Unified Power Format was developed within Accellera and the first version published in 2007. It specifies the power intent of an electronic design and includes elements such as power supply definitions, power control requirements, level shifters, isolation and memory retention.
What is Verdi Synopsys?
The Verdi system lets you focus on tasks that add more value to your designs, by cutting your debug time, by typically over 50%. These time savings are made possible by unique technology that: Reveals the operation of and interaction between the design, assertions, and testbench.
What is a power state table?
UPF (Unified Power Format) provides mechanism to specify power intent for power management of low power designs. A power state table (PST) defines the legal combinations of port states, i.e., those combinations of port states that can exist at the same time during operation of the design.
What is power management verification in RTL design?
Put simply, power management verification must occur early in the design cycle if designers are to minimize the impact of any bugs on project deadlines. Traditional RTL simulation environments incorporate no concept of power because the simulator itself assumes the whole design is always powered-on.
What is power-aware ibis modeling?
Power-aware IBIS modeling can be used in all simulation types including DDRx analysis, to study the power effects of timing and signal quality. This tool can model simultaneous switching noise (SSN), critical for designing next-generation memory interconnects.
What are the limitations of traditional verification tools?
Traditional verification tools struggle to deal with today’s increasingly sophisticated power management technologies. One major limitation is that they cannot deal with varying power states because they make a built-in assumption that devices are always fully powered on.
Why run power-aware simulations at RTL?
The goal of these simulations is to catch as many power-management implementation issues as possible at the RTL. Typical issues here include: always-on paths. By running dedicated power-aware test cases in the power-aware flow, we were able to catch critical bugs, including these examples:
