摘要: With the increase of design complexities and decrease minimal feature sizes, IP reuse is becoming a common practice while crosstalk critical issue that must be considered. This work presents two macro-models for specifying timing behaviors combinational hard blocks with effects. The gray-box model keeps coupling graph lists conditions on relative input arrival time combinations couplings not to take effect. black-box stores output response windows basic set combinations, computes any given combination through union some in set. Both are conservative, can greatly reduce pessimism existing conventional "pin-to-pin" model. first deal macro-modeling consideration
