Abstract

Register file logic verification historically involves comparing two human generated logic sources such as a VHDL code file and a circuit schematic for logic equivalence. This method is valid for most cases, however it does not account for instances when both logic sources are equivalent but incorrect. This report proposes a method to eliminate this problem by testing logic coherency of various sources with a golden logic source. This golden logic source will be generated by a register file simulation program which has been developed to simulate accurate regfile I/O port data. Implementation of this simulation program for logic verification will eliminate the accuracy problem stated above, in addition the logic simulation time for the new method has also been reduced by 36% compared to the former method.
