ABSTRACT:
A computerized method of generating a truth table of a cell in a library of circuit cells includes representing basic elements of the cells in a hardware description language, representing each cell as a set of equations in that language and parsing the equations each in accordance with a respective abstract data tree of which the `leaves` or extremities are signal values or constants. The parsing of each equation yields a respective partial truth table. The partial truth tables are merged to provide a complete truth table, which is preferably subjected to Boolean and/or expression optimization to reduce the number of entries in the truth table.
