Design and Verification of AXI BUS Encrypt Module
With the development of SoC technology and information safety needed,this paper provides RTL designs which encrypt and decrypt the AXI on-chip bus on-the-fly with AES arithmetic,to ensure the path to be safety from CPU to slave.The soft-IP provides the support for the AXI Burst transfer mode with some inside FIFO modules.The AES arithmetic can work in ECB and CTR mode and encrypt or decrypt paralleled.And the paper provides a structured universal verification methodology(UVM)verification platform to complete the constraint-random test and coverage analysis with the APB and AXI VIPs.At last using the Synopsys simulation tool—VCS to provide the coverage report.
ABSTRACT The article presents the results of an experimental and numerical investigation on Azzone Visconti bridge, a 14th century arch bridge in Lecco (northern Italy). Starting from the historical data and from an extensive mechanical characterization of both the soil constituting the riverbed and of the masonry constituting the piers, the aim of the study is to investigate the bearing capacity of the bridge. A testing loading scheme defined according to the current Italian Code is adopted to check the structural behavior. A simplified finite element structural model was conceived and calibrated as a control tool to safely perform the experimental tests. Post-test nonlinear finite element analyses have allowed the prediction of the bridge bearing capacity and the definition of the bridge class according to the Italian regulations.
