43、 not part of IEEE Std 1801-2015, IEEE Standard for Design and Verification of Low-Power, Energy-Aware Electronic Systems. The purpose of this standard is to provide portable, low-power design specifications that can be used with a variety of commercial products throughout an electronic system design
44、, analysis, verification, and implementation flow. When the electronic design automation (EDA) industry began creating standards for use in specifying, simulating, and implementing functional specifications of digital electronic circuits in the 1980s, the primary design constraint was the transistor
45、 area necessary to implement the required functionality in the prevailing process technology at that time. Power considerations were simple and easily assumed for the design as power consumption was not a major consideration and most chips operated on a single voltage for all functionality. Therefor
46、e, hardware description languages (HDLs) such as VHDL (IEC 61691-1-1/ IEEE Std 1076a)and SystemVerilog (IEEE Std 1800b) provided a rich set of capabilities necessary for capturing the functional specification of electronic systems, but no capabilities for capturing the power architecture (how each e
47、lement of the system is to be powered). As the process technology for manufacturing electronic circuits continued to advance, power (as a design constraint) continually increased in importance. Even above the 90 nm process node size, dynamic power consumption became an important design constraint as
48、 the functional size of designs increased power consumption at the same time battery-operated mobile systems, such as cell phones and laptop computers, became a significant driver of the electronics industry. Techniques for reducing dynamic power consumptionthe amount of power consumed to transition
49、 a node from a 0 to 1 state or vice versabecame commonplace. Although these techniques affected the design methodology, the changes were relatively easy to accommodate within the existing HDL-based design flow, as these techniques were primarily focused on managing the clocking for the design (more clock domains operating at different frequencies and gating of clocks when logic in a clock domain is not needed for the active operational mode). Multi-voltage power-management methods were also developed. These methods did not directly impact the functionality of the design, re
