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, WidthAdjustSynthesizer simply calls Logic.takeBot with operator.getBusWidth() to take the correct number of bits from input.

Specified by:

createCell in interface OperatorSynthesizer

Overrides:

createCell in class LogicSynthesizer

Parameters:

parent - the parent Cell for the newly created cell

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.
