DesignWare IP Solutions for AMBA - APB Advanced Peripherals

The DesignWare APB Advanced Peripheral components include many of the industry’s commonly used interface IP. The highly configurable components allow design engineers to tailor the components to their desired design requirements. Comprehensive subsystems can be quickly assembled using coreAssembler, which is a graphical subsystem assembly tool. coreAssembler automates the subsystem assembly and IP configuration, including the creation of an initial verification testbench environment using DesignWare Verification IP, All of reduces the time to first simulation.

The DesignWare APB Advanced Peripheral components for AMBA are available in encrypted format as part of the DesignWare Library. RTL source code is available as a separate license, on a pay-per-use basis as part of the DesignWare APB Advanced Peripherals license package.
