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
Compliant with version 2.0 Safe-by-Wire Plus Specifications
Full SBWP Slave functionality
Supports occupant restraints bus for deployable devices and for sensors
o Deployment bus for squibs and optionally for static occupancy sensors
o sensor bus for smart or simple impact sensors, dynamic occupancy sensors and optionally for static occupancy sensors
o combined sensor / deployment bus
Supports Bi-directional two-wire bus with integrated power distribution
o Master-Slave operation o Babbling-idiot protection for deploy messages from master o Provides optional interrupt possibilities for smart impact sensors
o Optional multi-master operation
Supports variable bus speed with self-clocking slaves
o 20 kbps, 40 kbps, 80 kbps or 160 kbps +/- 13%
o Data throughput example: at 160 kbps, (=160 kHz):
* Transfer time of a deploy message controlling up to 12 deployable devices < 200 μs
