Description

Hi, I am working on the physical ASIC implementation of this IP. I am integrating this IP into a new chip and I am having issue with the xilinx dual ports dual clock memories instantiated into dualmem_widen8.sv and dualmem_widen.sv
I would like to know how this memories are used by the IP and if the two ports 2 clocks mem are strictly necessary for it.
Thank you

Research direction

Start by reading dualmem_widen8.sv and dualmem_widen.sv, then trace where these memories are instantiated and how their ports and clocks connect to the Ethernet MAC. Done means documenting how the memories are used and whether both dual-port, dual-clock interfaces are required for the IP or can be replaced for ASIC integration.
