Hello, I am trying to build the project targeter on artya7 board, manualy (Without using FuseSoC) for better understanding. I found out that the file "ram_2p.sv" instantiates a module "prim_ram_2p" that can not be found anywhere. In addition, there were some other files that were instantiated but not found anywhere. Regardless of those issues the verilator simulation was run without any errors. I would like to know why there are no "prim_ram_2p.sv" and how did the verilator simulation still run? Thanks
