Synopsys IP Solutions for AMBA - Infrastructure & Fabric

The Synopsys Infrastructure and Fabric components for AMBA® 2.0, AMBA 3 AXI™, and AMBA 4 AXI with ACE-Lite support include all the essential building blocks for almost all AMBA-based subsystem topologies, including AMBA 2, AMBA 3 AXI, and AMBA 4 AXI. The components are highly configurable, providing designers with the flexibility to tailor the components to their design requirements. Comprehensive subsystems can be quickly assembled using coreAssembler, an included graphical based subsystem assembly tool. coreAssembler automates the subsystem assembly and IP configuration which includes the creation of an initial verification testbench environment enabled by Synopsys Verification IP, thus reducing the time to first simulation.

The Synopsys Fabric components for AMBA are available in encrypted format as part of the DesignWare Library. RTL source code with additional differentiated features is available for license separately, on a pay-per-use basis as part of the Synopsys Cores AMBA Fabric license package.
