Description     : This function tests qam_gen_unpack_lookup with 2 test cases 
                  and finds cycle count for qam size of 8 and number of 
                  symbols = 255 and 256.
                    1. Test1 - Number of symbols = 255
                    2. Test1 - Number of symbols = 256
