The Advanced Microcontroller Bus Architecture (AMBA) is an on-chip bus architecture used to Design high performance embedded microcontrollers and strengthen the reusability of IP core and widely used interconnection standard for system on chip (SOC). AMBA AHB (advanced high performance bus) is the highperformance bus means higher bandwidth or high clock frequency system modules. AMBA APB (advanced peripheral bus) as the name suggest used to connect peripheral to the architecture, peripherals like UART, Timer, keypad, PIO etc. this are part of low performance bus and it is optimized for low power consumption and interface reduced complexity to support peripheral functions. In this the functions of the AHB2APB Bridge to make the signals compatible with the high performance bus i.e. AHB with low performance bus i.e. APB, to do so we have to write the DUT code in Verilog and all other test case code in system Verilog, further have verified all the functions of bridge protocol using QuestaSim tool. The code coverage and functional coverage and functional verification of the Bridge RTL design is 97% covered by using QuestaSim
