On analysis of fabricated polymorphic circuits

The paper describes a reconfigurable polymorphic chip REPOMO32, experiments carried out with this chip and provides report on important experiences with regard to practical applications of digital polymorphic circuits sensitive to the power supply voltage (V_dd). REPOMO32 contains array of 32 configurable logic elements which can perform polymorphic NAND/NOR function controlled by the level of the V_dd. Moreover, it can be declared as the first fabricated chip of this kind which basically allows the user to design more complex circuits than only a few gates.
