Five members of the Power Manager II family, including the award winning ProcessorPM, provide the programmable building blocks required to integrate one or more functions shown above. The PAC-Designer software tool, which can be downloaded for free, is used to implement these functions in software. Designs can be simulated using the Aldec Active-HDL Lattice Web Edition (LWE) simulator.
