|NOT||1||Opposite to the input signal value.|
|AND||1 or more||Conjunction of the input signal values.|
|NAND||1 or more||Negation of the conjunction of the input signal values.|
|OR||1 or more||Disjunction of the input signal values.|
|NOR||1 or more||Negation of the disjunction of the input signal values.|
|DFF||1||Same as the input signal. Returned with the delay of one tick of discrete time.|
junctionis the name of the junction. A line describing the interesting junction looks like
junctionis the name of the junction. A junction name consists of small and capital Latin letters and digits and the underline character "_". The length of each name is less than 64 characters.
j1 = op(j2), where
j2are the names of junctions and
DFF. It can also look like
j1 = op(j2[, j3...]), where
j's are the junction names and
NOR. There will be no more than 5 · 103 junctions.
INPUT VALUES. Each of the following lines contains a sequence of zeroes and ones. Amount of digits equals to the amount of input signals. You should match these binary values to the input signal values, in the order the input signals given. There are no more than 500 lines in this block. Please refer to the sample for the details.
