Blockdiagram

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 blocs meaningfull
• Inputs are on the left, outputs are on the right
• Higher abstraction are on top, lower in the bottom, it 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
