One of the main research directions of polymorphic electronics is focused on
various issues connected with the design of basic polymorphic components -
polymorphic gates. Without a sufficient amount of polymorphic gates offering good
properties, conventional electronics will be most likely the preferred way before
polymorphic electronics in application scenarios targeting multifunctional
behaviour or reconfiguration. The main objective of this paper is to propose
a library called PoLibSi which contains eight sets of efficient bi-functional
two-input polymorphic gates, whose function is selected by mutual polarity of
dedicated power rails. The gate sets differ in the transistor type (conventional
MOSFET, emerging double-gate ambipolar transistors), feature the gate sets were
optimized to (transistor count, delay, power consumption) and input impedance
constraint. The individual gates were designed by means of using an evolutionary
based approach and further validated by HSPICE simulations. Each gate
implementation includes a schematic, HSPICE description and simulation results.
Moreover, propagation delay and power consumption is provided for all MOSFET
based gates. Furthermore, each gate set is complete - it provides efficient
implementation of any pair of two-input Boolean functions. Besides providing
polymorphic gates with better properties to the research society, the aim of the
proposed library is to improve the synthesis of polymorphic circuits in terms of
the resulting size, as it is also shown in the paper. Finally, the PoLibSi
library is available at: www.fit.vutbr.cz/~inevoral/polibsi
