Method Detail

getPinTypeOfNthPin

public PinType getPinTypeOfNthPin(int n)

Specified by:

getPinTypeOfNthPin in class Part

Returns:

the PinType for the nth pin

getLength

public double getLength()

Specified by:

getLength in interface PartReport.PartReportable

Overrides:

getLength in class Part

getWidth

public double getWidth()

Specified by:

getWidth in interface PartReport.PartReportable

Overrides:

getWidth in class Part

numSeries

public int numSeries()

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

touchesOnlyOneDiffAndNoGate

public boolean touchesOnlyOneDiffAndNoGate(Wire w)

Returns:

true if Wire w connects to exactly one diffusion and w doesn't connect to any gate

isCapacitor

public boolean isCapacitor()

Returns:

true if Mos is a capacitor. That is both diffusions are connected

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

parallelMerge

public boolean parallelMerge(Part p,
                             NccOptions nccOpt)

Description copied from class: Part

This method attempts to merge this Part in parallel with another Part

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

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

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:
