// Description: AXI3 Slave Converter
// This module instantiates Address, Write Data and Read Data AXI3 Converter
// modules, each one taking care of the channel specific tasks.
// The Address AXI3 converter can handle both AR and AW channels.
// The Write Respons Channel is reused from the Down-Sizer.
//
// Verilog-standard: Verilog 2001
