DigitalBus API

The Constructors

Groups of signals are represented by a DigitalBus. For example, a processor address bus or data bus. The DigitalBus name must be in the format bus_name[MS:LS]. Where MS is the most significant signal position and LS in the least significant signal position.

DigitalBus(TimingAnalyzer taApp, String name, double riseTime, double fallTime, String startState, String stateFormat)

The signal height and space above are all set to the default values.

DigitalBus(TimingAnalyzer taApp, String name, String startState, String stateFormat)

The signal height, space above, rise time, and fall time are all set to the default values.

Adding DigitalBus Signals

addDigitalBus(DigitalBus myBus)

Adds a DigitalBus to this timing diagram. The DigitalBus instance is required as the argument.

timDiagram.addDigitalBus(myBus)

addDigitalBus(String name, String startState, String stateFormat)

Adds a DigitalBus to this timing diagram. It creates a new instance of a DigitalBus object.

Returns a DigitalBus object.

dbus = timDiagram.addDigitalBus("ADDR[15:0]","Z","Hex")

Changing DigitalBus Parameters

getBusName(String name)

This returns a String that is the name part of name[MS:LS]. The example below returns “ADDR”.

busName = dbus.getBusName("ADDR[15:0]")

getBusNameX(String name)

Returns and integer that is the DigitalBus MS signal index. The example below returns 15.

msIndex = dbus.getBusNameX("ADDR[15:0]")

getBusNameY(String name)

Returns an integer that is the DigitalBus LS signal index. The example below returns 0.

lsIndex = dbus.getBusNameY("ADDR[15:0]")

getStateFormat()

Returns a String that is the DigitalBus State Format. It could be “Hex”,”Bin”,”Dec”, or “Text”.

stateFormat = dbus.getStateFormat()

setStateFormat(String stateFormat)

Set the DigitalBus State Format. This sets the current state format to a new value and changes all the bus values to the new state format.

dbus.setStateFormat("Hex")

getNumBits()

Returns an integer that is the number of signals in the DigitalBus.

numSignals = dbus.getNumBits()
