....electronic circuit as chromosome in an evolutionary process in which the standard genetic operators such as initialisation, recombination, selection are carried out. The circuits may be evaluated using software simulation models [1] 2] 3] 4] or alternatively evolved entirely in hardware [5], 6 , 7] 8] In this paper, we limit our focus to combinational logic circuits, which contain no memory elements. Such circuits contain no feedback paths. Note that this approach can be easily extended for the combinational multiple valued logic circuits. The approach is an extension of ....

....in such a way that the device cannot be damaged. Consequently it is possible to place a random configuration (in the form of a serial bit stream) directly on to the device the CLB based devices do not allow this. The direct evolution of configuration bit streams is the approach taken by Thompson [Tho96]. He evolved a circuit which could discriminate between square wave input signals of 1 and 10 kHz. He used a GA to create bit strings to define the configuration of a 10 x 10 array of cells on the Xilinx 6216 FPGA. Each chromosome consisted of 1800 bits (18 per cell) These bit strings configured ....
