Single Edge Nibble Transmission (SENT) is a single-wire, serial unidirectional communication protocol. It is intended for use in applications where high resolution sensor data needs to be communicated from a sensor to an Engine Control Unit (EUC). It is intended as a replacement or the lower resolution methods of 10 bit A/D's and as a simpler low cost alternative to CAN or LIN in automotive industry. SENT (SAE J2716) Verification IP are reusable components that provide ready made verification environment. Compatible with Single Edge Nibble Transmission (SENT) specifications and supports all the frame types. SENT (SAE J2716) includes an extensive test suite covering most of the possible scenarios. It can perform all protocal tests and moreover it allows an easy generation of very high number of patterns and a set of specified patterns to stress the DUT.
SENT (SAE J2716) Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
SENT (SAE J2716) Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
