Design of arbitrated I2C protocol with DO-254 compliance
K B Bharath, K V Kumaraswamy, Roopa K Swamy · 2016
This paper shows the working of an I2C protocol for multiple masters-multiple slave configuration operation. When multiple masters are considered, it is necessary to know which master has got the bus. To know this, Arbitration technique has been implemented by satisfying DO-254 standards. DO-254 standard provides an assurance for the design with reliability, reusability and assurance for the design which can be used for real time applications like airborne, military, and avionics application. To implement DO-254 standard, ReqTracer, HDL designer, Questasim, and Precision RTL Plus tools are used at different phases of the FPGA flow.
