A blockdiagram, as the name implies, contains blocks.
Before drawing a blockdiagram, one needs an overview of the required functionality in the collection of blocks that would be the system-to-be.
The principal parts or functions, in the system-to-be, are represented by blocks connected by lines, that show the relationships of the blocks.
Block diagrams can represent both Hardware, Software or Mechanical engineering.
In order to draw a block diagram, follow these simple rules :
- Name blocks meaningful
- Inputs are on the left, outputs are on the right
- Higher abstraction are on top, lower in the bottom, if this is possible to distinguish
- For example physical hardware blocks will be drawn in the bottom, and the user application will drawn on the top
