T2M Automotive SBWP Slave IP

SBWP Slave IP

Description

SBWP Slave is full-featured, easy-to-use, synthesizable design, compatible with standard protocol of Safe-byWire Plus Specification. Through its SBWP compatibility, it provides a simple interface to a wide range of low-cost devices. SBWP Slave IIP is proven in FPGA environment. The host interface of the SBWP Slave can be simple interface or can be AMBA APB, AMBA AHB, AMBA AHB-Lite, AMBA AXI, AMBA AXILite, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol. SBWP Slave IIP is supported natively in Verilog and VHDL
