Constructor Detail

Resistor

public Resistor(PrimitiveNode.Function type,
                NccNameProxy.PartNameProxy name,
                double width,
                double length,
                Wire w1,
                Wire w2)

Method Detail

getPinCoeffs

public int[] getPinCoeffs()

Description copied from class: Part

Here is an accessor method for the coefficient array for this Part. The terminal coefficients are used to compute new hash codes.

Specified by:

getPinCoeffs in class Part

Returns:

the array of terminal coefficients for this Part

valueDescription

public java.lang.String valueDescription()

Description copied from class: Part

Report the numeric values of this Part, for example: width, length, resistance.

Specified by:

valueDescription in class Part

Returns:

a String describing the Part's numeric values.

hashCodeForParallelMerge

public java.lang.Integer hashCodeForParallelMerge()

Description copied from class: Part

Compute a hash code for this part for the purpose of performing parallel merge. If two parallel Parts should be merged into one then hashCodeForParallelMerge() must return the same value for both Parts.

Specified by:

hashCodeForParallelMerge in class Part

getWidth

public double getWidth()

Specified by:

getWidth in interface PartReport.PartReportable

Overrides:

getWidth in class Part

getLength

public double getLength()

Specified by:

getLength in interface PartReport.PartReportable

Overrides:

getLength in class Part

connect

public void connect(Wire ss,
                    Wire ee)

parallelMerge

public boolean parallelMerge(Part p,
                             NccOptions nccOpt)

Never perform series/parallel combination of resistors. For layout resistors, resistance is a vendor dependent function of resistor width and length. We'll simply annotate resistor width and length and compare these between schematic and layout. See Jon Lexau for rationale.

Specified by:

parallelMerge in class Part

Parameters:

p - the other Part with which to merge

nccOpt - NccOptions. Used for size tolerance specification.

Returns:

true if merge was successful, false otherwise

typeCode

public int typeCode()

Description copied from class: Part

returns a unique int value for each distinct Part type

Specified by:

typeCode in class Part

getPinTypeOfNthPin

public PinType getPinTypeOfNthPin(int n)

Specified by:

getPinTypeOfNthPin in class Part

Returns:

the PinType for the nth pin

typeString

public java.lang.String typeString()

Description copied from class: Part

returns String describing Part's type

Specified by:

typeString in interface PartReport.PartReportable

Specified by:

typeString in class Part

connectionDescription

public java.lang.String connectionDescription(int n)

Description copied from class: NetObject

human readable description of things connected this NetObject

Specified by:

connectionDescription in class NetObject

connectionDescription

public java.lang.String connectionDescription(Wire w)

Description copied from class: Part

comma separated list of pins connected to w

Specified by:

connectionDescription in class Part
