This paper presents a simple environment for the verification of AMBA 3 AXI systems in Verification IP (VIP)
production called VIPACES (Verification Interface Primitives for the development of AXI Compliant Elements and
Systems). These primitives are presented as a not compiled library written in SystemC where interfaces are the core of
the library. The definition of interfaces instead of generic modules let the user construct custom modules improving the
resources spent during the verification phase as well as easily adapting his modules to the AMBA 3 AXI protocol. This
topic is the main discussion in the VIPACES library. The paper focuses on comparing and contrasting the main
interconnection schemes for AMBA 3 AXI as modeled by VIPACES. For assessing these results we propose a validation
scenario with a particular architecture belonging to the domain of MPEG4 video decoding, which is compound by an
AXI bus connecting an IDCT and other processing resources.
