DigitalBus API

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()
