Preface
About This Manual
This document describes how to capture the power intent for your design using the Si2 Common Power Format (CPF), a standardized format for specifying power-saving techniques early in the design process, to deliver an end-to-end low-power design solution to IC engineers.
To use this manual, you should be familiar with IC power consumption concepts.

Documentation Conventions
To aid the readers understanding, a consistent formatting style has been used throughout this manual.
The list below describes the syntax conventions used for the CPF constraints.
literal- Nonitalic words indicate keywords that you must type literally. These keywords represent command or option names.
arguments and options- Words in italics indicate user-defined arguments or options for which you must substitute a name or a value.
- |
- Vertical bars (OR-bars) separate possible choices for a single argument.
- [ ]
- Brackets denote options. When used with OR-bars, they enclose a list of choices from which you can choose one.
- { }
- Braces denote arguments and are used to indicate that a choice is required from the list of arguments separated by OR-bars. You must choose one from the list.
- { argument1 | argument2 | argument3 }
- ...
- Three dots (...) indicate that you can repeat the previous argument. If the three dots are used with brackets (that is, [
argument]...), you can specify zero or more arguments. If the three dots are used without brackets (argument...), you must specify at least one argument, but can specify more.
#- The pound sign precedes comments.
