I2C slave
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
I2C target-mode block with programmable 7-bit address and register-mapped data interface.
Simulated. The RTL is lint clean and passes its self-checking testbench against a reference model in simulation. It has not been run on an FPGA board or in silicon.
