AUTOMATIC DESIGNING METHOD FOR ANALOG ELECTRIC CIRCUIT

摘要

PROBLEM TO BE SOLVED: To automatically design a large scale analog electric circuit without human intervention by integrally converting a transfer function and generating a new transfer function according to a hereditary programming when output is not judged as a desirable result based on integral conversion. ;SOLUTION: A transfer function F between an inputted analog signal x and an outputted analog signal y is set as an initial function F init as shown with a number F=F init (S11). The input x is integrally converted (expressed as z) and input X to be indicated as a number X=z(x) is calculated (S12). Output y is calculated according to a number Y=FX (S13). And the output y is inversely and integrally converted (expressed as z-1) and the output y to be indicated with a number y=z-1 is calculated (S14). The calculated output y is judged whether it is desirable output or not (S15). When the output y is judged as NO here, the new transfer function F is generated according to the hereditary programming next (S16). Steps S13 to S15 are repeatedly executed until the output y is judged as YES according to the generated new function F.;COPYRIGHT: (C)2000,JPO
