I added the file name in the custom code as well as simulation target. But I get the following error message while generating code: Microsoft (R) Program Maintenance Utility Version 10.00.30319.01 Copyright (C) Microsoft Corporation. All rights reserved.

Are there any header files your .c file depends on? The errors you're getting suggest that something was not properly defined.
BusAtruProtectionlib.lib(BusAtruProtection.obj) : error LNK2019: unresolved external symbol UpdateAtruDiffVoltage referenced in function joeylifcnq
BusAtruProtectionlib.lib(BusAtruProtection.obj) : error LNK2019: unresolved external symbol InitAtruVoltageBuffer referenced in function joeylifcnq
The "unresolved external symbol" error suggests that these variables "UpdateAtruDiffVoltage" and "InitAtruVoltageBuffer" are not defined in the right place. Perhaps these need to come from a header file.
