Abstract: The maximum fanin number and maximum fanout number N_fanin(max) of gate circuit under the constraint of the microelectronic technological lever were translated into configuration parameter constraints based on the optimizing design of basic circuit unit and combination scenario of TC²CLA by means of analytic and induction inculcation.The constraint formula of these bit number of classesi_jm,maximum hierarchy number of the module M_j of configuration parameter of TC²CLA and N_fanin(max) & N_fanin(max) of gating circuit were deducted.The optimizing parsing table were given at the of the paper.The constraints of configuration parameter(i_jm、M_j) of TC²CLA were given in the formulae and optimizing table,the foundation for the overall optimal design and expanding operand bit of hybrid-modules TC²CLA and its optimizing sequence & without writing time sequence was laid.
