Embedded systems and Systems on Chip (SoC) are becoming extremely complex architectures, containing tens or hundreds of digital, analog,R.F and software blocks. For most applications, power management is a major consideration and power conservation is a major design decision.

VisualSim Power Toolkit

VisualSim Power Library is the first solution to enable dynamic power tracing and accurate system-level evaluation of the power consumed by different architecture options. With the addition of this library, performance, power and functionality can be explored concurrently for the IP, SoC, semiconductor and system. The library provides four main capabilities-

• Power table
  
• Power management toolkit and power tracking RegEx function
  
• Battery models for NiCd, LiON, Alkaline and over 5 other types
  
• Energy harvester- Solar, wall socket, motor, Nuclear, Wind and Generic

Using the Power table, designers can measure power, experiment with management options like power gating and sleep modes, vary the number of states/process/devices and optimize the specification to meet the deadline. The power exploration designer can be used to size the battery capacity, energy harvester requirements, battery life based on activity, cooling requirements and evaluating the savings for different management conditions.
