1. SYSTEM OVERVIEW

Please refer to the DigART Software Requirements Analysis Report for the system overview.

2. DIGART WIDE DESIGN DECISIONS DigART will be developed using JAVA programming language in NetBeans under Windows. A layered architecture will be applied for the DigART. Layer definitions and the components of these layers are given in Section 3. The main benefit to apply a layered architecture in DigART is to make easy to develop the project within components individually. The other benefit is the reusability of the layers and the components that can be used in other projects. Another benefit is the exchangeability that individual layer implementation can be replaced by semantically equivalent implementations without great efforts. Keeping the dependencies local is another advantage of this architecture. Standardizing the interfaces between layers usually confines the effect of code changes to the layer that is changed.

3. DIGART ARCHITECTURAL DESIGN

3.1. DIGART LAYERS

DigART software consists of the three layers; Presentation Layer, Domain Layer and Service Layer as shown in the Figure 1. Each layer contains components which are shown in Figure 1. The arrows between the components show the interactions between components. The capabilities of each component will be described in detail in the sections 3.1.1 , 3.1.2 and 3.1.3. Some of the interactions between components will be specified with sequence diagrammes in section 4.

3.1.2.1.2. Sequence Diagrams

3.1.2.1.2.1. Sequence Diagram For Insert Operations The user Selects an item from the tool box to draw on the canvas. This is sent to the DrawingPanel class by the method SetItemToDraw(). Then the coordinates of the clicked position is also sent there. Drawing panel creates a new CommonDataItem object and sets the fields of it with the functions shown below. Then the object is inserted to the vector which is hold by class Items. The function of DrawingPanel class DrawItems() calls the Items’s class’s method DrawListItems in oreder to draw all the items which are stored in vectors to the canvas.

3.1.2.1.2.2. Sequence Diagram For Edit Operations In the below sequence diagram the basic edit operations which are copy, paste, cut, delete and update are shown. For

copy and paste functions firstly, user clickes on the canvas to select in item. MousePressed and SelectItem methods

returns make call the SeachItem method of the Items class. This method returns the ID of the selected item. With the

CopySelectedItem method of the Drawing Panel, Items class’s CopyItem() function is called and returns the copied

object and the selected item is set with this item’s ID. All other edit operations occurs with similar flows.

3.1.2.2. SIMULATION COMPONENT Simulation is the component used for simulation operations. It uses JHDL Simulation class to simulate the curcuits in real time without compiling. Simulation operations are divided into to 2 cases. One of the cases is the simulation of the currently displayed curcuit and the other is the simulation of the curcuits sent by the Script Component. Either way it converts to CommonDataWire type vector to JHDLFormat and sends to JHDL, then converts it back to CommonDataWire type vecor. Simulation takes place in JHDL.

This method of ScriptHandler Class is responsible for syntax checking of the given script. It writes the error found to the interpreteerror string.

3.1.2.3.2. Sequence Diagram of Script Component This sequnce diagram is based on the flow of script interpretation.

Firstly GUI calls the RunScript method of ScriptHandler class and sends the text in as string which is written in the script text box. Then ScriptHandler method calls the SyntaxValidater method for checking that if the syntax is valid or not. Then the Parse method will called for parsing the text which is written in the script text box. After that GetFileNames method will be called and sends the folder parh to the File component for getting the file names in it. GetFileContent method will be called for knowing the files content for all files in the folder. For this purpose GetFileContent method sends the path of the file to the File component. Then SetInputValues method will be called for setting the input values of the CommonDataWire which was read from the script text box. After that SendToSimulation method will be called for knowing the output values of the circuit design of the file. This method will sent the CommonDataWire object to the Simulation. Lastly for checking the output values CheckOutputValues method will be called.
