DigitalBus API

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. Valid state formats are “Hex”,”Bin”,”Dec”, or “Text”.

Adding DigitalBus Signals

addDigitalBus(String name, String startState, String stateFormat)

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

Signal height, space above, riseTime, and fallTime are set to default values.

Returns a DigitalBus object.

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

addDigitalBus(String name, String startState, String stateFormat,

double riseTime, double fallTime)

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

Signal height and space above are set to default values.

Returns a DigitalBus object.

dbus = timDiagram.addDigitalBus("ADDR[15:0]", "Z", "Hex", 2.0e-9, 2.0e-9)

Getters and Setters

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()
