Method Detail

createCell

public Wire createCell(Logic parent,
                       DFVertex operator,
                       Wire[] inputWires)

Create a cell from the given DFVertex operator. This method will create the appropriate cell with parent as its parent and input wires from inputWires. It will return a new wire created for the output. The new cell should implement the function defined by operator.getOperation()

Specifically, EqSynthesizer looks for a 1-bit constant as one of its inputs and creates either a wire or an inverter. If neither input is a 1-bit constant, then EqSynthesizer will throw an exception.

Specified by:

createCell in interface OperatorSynthesizer

Overrides:

createCell in class LogicSynthesizer

Parameters:

operator - an operator in a DataFlowGraph specifying the operation to be performed by the new cell.

inputWires - The input wires for this operator (ignored)

Returns:

the output wire of the newly created cell.
