Ai_Ar Posted June 22, 2021 Report Share Posted June 22, 2021 Hi, I have a top level reg map set up as below. In my adapter I am trying to retrieve all the registers by address of incoming reg_item in bus2reg function to simulate burst condition. The get_reg_by_offset call returns null every time. I don't understand why the address is not found considering all the registers have unique offsets. Infact I retrieved the base address of the incoming reg_item to check if I can the register before incrementing for next offset, but it cannot find the register with base address. Any help is appreciated. Top register file: TOP_map = create_map(.name("TOP_map"), .base_addr('hFE00), .n_bytes(1),.endian(UVM_LITTLE_ENDIAN),.byte_addressing(1) ); default_map = CONTROL_TOP_map; TOP_map.add_submap(this.int_reg_blk.I2C_INT_map, .offset(8'h7C)); TOP_map.add_submap(this.scan_blk.SCAN_CTL_map, .offset(8'h84)); TOP_map.add_submap(this.ctrl_int_reg_blk.HOR_CTRL_map, .offset(8'h94)); TOP_map.I2C_INT_map.add_hdl_path("********", "RTL"); //didn't want to add proprietary code paths get_reg_by_offset call uvm_reg_item in_item = get_item(); base_addr = in_item.map.get_base_addr(); if(!(in_item.map.get_reg_by_offset(base_addr))) `uvm_error(get_type_name(), "Register not found in reg map") else registers[i] = in_item.map.get_reg_by_offset(base_addr+1); Quote Link to comment Share on other sites More sharing options...
