According to spec IHI0022D_amba_axi_protocol_spec section A2.1 page number: A2-28
"All signals are sampled on the rising edge of the global clock "\n\n Q) Should RESET_N also be sampled on the rising edge only?\nSection A3.1.2, says
\"The AXI protocol uses a single active LOW reset signal, ARESETn. The reset signal can be asserted asynchronously, but de-assertion must be synchronous with a rising edge of ACLK.
During reset the following interface requirements apply:
• a master interface must drive ARVALID, AWVALID, and WVALID LOW
• a slave interface must drive RVALID and BVALID LOW
\"
Q) How a design should implement with respect to reset. ( Should it implement Asynchronous reset)? |
