I need to draw software code like they did for hardware in circuit schematic diagrams.
Suppose we have function A, function B.
Function B calls function A...
Can we draw blocks with inputs & outputs, and connect these blocks together ?
Is there any software, which can generate such diagrams ?
It does not have to draw complicated UML diagrams, the diagram simply represent the function block inputs & outputs, that is enough, plus, it also represent the calling hierarchy through input & output lines connected, like they did in circuit schematic diagrams.
(output pin of chip A connects to input pin of chip B)
