The circuit is combinational and checks the essential ARP fields.
Behaviour
0x0806, HTYPE 1, PTYPE 0x0800, and OPER 1 are required.i_target_ip must equal i_local_ip.o_is_request=1 only if all conditions are true.| Signal | Direction | Width | Description |
|---|---|---|---|
i_ethertype | Input | 16 bits | Input ethertype |
i_htype | Input | 16 bits | Input htype |
i_ptype | Input | 16 bits | Input ptype |
i_oper | Input | 16 bits | Input oper |
i_target_ip | Input | 32 bits | Input target ip |
i_local_ip | Input | 32 bits | Input local ip |
o_is_request | Output | 1 bit | Output is request |
