How do you connect an AHB-lite Slave to a full AHB system?

Applies to: AHB

Answer

An AHB-lite slave is already AHB compliant, with only the HRESP output (indicating OKAY or ERROR) needing to be extended to 2 bits to be compatible with the full AHB HRESP[1:0] bus. HRESP[1] would be driven to logic '0' (1'b0).
