Debugging techniques

The fundamental aim of a debugging methodology is to

restrict the introduction of untested software or hardware to a

single item. This is good practice and of benefit to the design

and implementation of any system, even those that use emula-

tion early on in the design cycle.

It is to prevent this integration of two unknowns that

simulation programs to simulate and test software, hardware

or both can play a critical part in the development process.

High level language simulation

If software is written in a high level language, it is

possible to test large parts ...
