APB clock-domain crossing bridge
Maturity simulatedTargets FPGA + ASICDifficulty EasyPriority 1
APB4 bridge between asynchronous clock domains using a request/acknowledge handshake, with timeout error response if the destination domain is unclocked.
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.
