Logic
A design is a combination of several design modules operating at
different frequencies and toggle rates. Each design module can have a
different amount of logic. For the most accurate power estimation,
partition the design into different design modules. You can partition your
design by grouping modules by clock frequency, location, hierarchy, or
entities.
Each row in the Logic section represents a separate design module. You
must enter the following parameters for each design module
■ Clock frequency (f
MAX
) in MHz
■ Number of combinational adaptive look-up tables (ALUTs)
■ Number of registers
■ Toggle percentage
