Lattice Sentry I²C Filter IP Core - Lattice Propel Builder User Guide
●SMBus Relay with filter (named I²C filter in this document) is designed to function as an invisible relay from the point of view of both Master and Slave devices on the bus. It is meant to be directly attached to the Master port and protect all Slave devices against malicious traffic generated from the Master port based on a whitelist of allowable commands set by the host (such asCPU, FPGA RoT design, and others). The filter IP is the subset of the SMBus protocol. SMBSUS# and SMBALERT# are not supported.
●The design is implemented in Verilog HDL. It can be configured and generated using the Lattice Propel™ Builder software. It can be implemented using the Lattice Radiant™ software and the Lattice Diamond®Place and Route tool. The module registers are accessed by the host (such asCPU, FPGA RoT design, and others) using a 32-bit Advanced High-performance Bus -Lite (AHB-Lite) interface.
