-- Referring to the Book "Structure and Interpretation of Computer Programs" 2nd Edition, by Harold Abelson, Gerald Jay Sussman (1996) .
Event Driven Simulation: In which Actions (Events) trigger further events that happen at a later point in time, which trigger further events and so on.
Objects to be modeled: -- Real Life elementary components:
- 1) Wires --- Carry binary signals : 0 / 1. They also have to perform some tasks (inform connected components) about change in their value.
- 2) Digital Function Blocks --- Which are connected between Wires carrying inputs to other wires - outputs. These need to listen for changes in the state of wires connecting these blocks. A change in the state of 1 wire might trickle down to changes in the neighboring wires based on the output of these function blocks.
- 3) Operations Queue --- to help model the time delay of performing various tasks during the simulation.
- 4) Probe --- To trigger on change in value and print value on screen
(2 Hours)
25th July
[2 Hours] Read further about Simulators, Digital Logic Blocks
26th July
[3 Hours] Read up about Test Driven Development, JUnit and Software Refactoring from the Library books on these topics
1 August
[5 hours] Updated the Design Study page. Finally added some small circuit and block diagram on the page. Thought about Modelling Components and Wires.
2 August
[1 Hour] Quickly generated a UML design for the first step
4 August
[30 Mins] Updated the wiki with some information and added the UML document]
