ALLTED is a personal computer oriented CAD system for nonlinear dynamic system design. It is based mostly on original algorithms and possesses some important adaptation features to ill-conditional tasks and DC, TR Stiffness. It provides a powerfull procedure of automatic determination of secondary response parameters (delays, rise, fall times, frequency band, resonance frequency,...etc) and calculation of function of this parameters. In following design these secondary parameters and their functions become variables which are optimized ( Which parameterical and functional contraints for one or multicriterional tasks) or for which sensitivities, WC, permissible toplerances and statistical characteristics (including histograms) are calculated
