Signals
Current DigiView hardware has either 18 or 36 physical channels. However, we like to think in
terms of symbolic names representing individual signals (clock,ALE) or groups of signals
(DataBus, Address) rather than channel numbers(0,1,2..). We start by defining SIGNALS in
terms of CHANNELS. This is the only place we deal directly with physical channels. The
remainder of the software deals in terms of signal names rather than channel numbers. When we
define signals, we are mapping a signal NAME to one or more physical channels. This also
makes it possible to share the same physical channel with multiple signal definitions (see: Signal
Editors 10 ).
Adding Signals to the Project
The create a Signal, select "Config->Signals..." from the main menu, which will open the
"Project Settings" window to the Signal Definition tab.
Double-Click on one of the "Define New Signal" selections to create a new signal or Highlight
your choice and select "Add". A new signal of the chosen type will be created and it's property
editor will appear. You can rename the signal, change the physical channels to use for this
signal definition and set all associated options from the signal's editor. (For details on signal
options, see the section: Signal Editors 10 )
Summary of the Project's Signals
The main purpose of the lower section of the config screen is to provide an overview of all
current signal definitions and their related channels. You can also Edit or Delete signals from
this section, determine each signal's type, its basic colors and its enabled status.The
configuration section is arranged in a grid with columns representing the physical channels
and one row per defined signal. Notice that the same channel can be assigned to multiple
signal definitions. In the image below, channel 0 has been assigned to the Bus, STATE,
Analog and STATE[1] signal definitions.
