We define what we mean by the term formal synthesis and delimit it from the other formal methods that can also be used to guarantee the correctness of an implementation. A possible classification scheme for formal synthesis methods is then introduced, based on which some significant research activities are classified and summarized. We also briefly introduce our own approach towards the formal synthesis of hardware. Finally, we compare these approaches from different points of view.

Research paper thumbnail of A recursive net-grid-type analog fractance circuit for any order fractional calculus

Furthermore, it finds out that our 1/2 order net-grid analog fractance circuit is superior to the classical 1/2 order tree-type one by comparing the structure and function of each other. On this bases, it further puts forward and discusses a general recursive net-grid-type analog fractance circuit for any order fractional calculus. The results educing by the paper are the basis for further theoretic research and engineering implement for structuring fractance circuit of any order fractional calculus.

No effort has been spared by the author to make his treatment clear and as simple as the subject matter will permit. The method of presentation is distinctively pedagogic. To electrical engineers and to engineering instructors, this exposition of the fundamentals of electric circuit theory and the operational calculus should be of great value.-EDITOR.
