4.3.3. Tri‑State Conduit Bridge

The Tri-State Conduit Bridge instantiates bidirectional signals for each tri-state signal while passing all other signals straight through the component. The Tri-State Conduit Bridge registers all outgoing and incoming signals, which adds two cycles of latency for a read request. You must account for this additional pipelining when designing a custom controller. During reset, all outputs are placed in a high-impedance state. Outputs are enabled in the first clock cycle after reset is deasserted, and the output signals are then bidirectional.
