for later use. Because of their simplistic nature, table based generators may be used by less skilled personnel to create interesting tests. There is a drawback to these generators however, as their implementation is generally restricted to simple architectures. Usage on more complex ISAs may result

Dynamic generators incorporate significant knowledge about the architecture being tested. They enhance the ability of less-skilled users to generate complex tests that can hit hard-to-reach corner cases without stumbling on subtle programming pitfalls. This added knowledge, flexibility and

Table based test generators are the simplest RTGs available. Creation of such generators can be accomplished relatively quickly, and maintenance requirements are often low. These generators work by capturing knowledge of the design's

ease-of-use is reflected in a more complex generator, and consequently the cost of creating and maintaining the generator are greater than for table-based or static generators.

Static generators are similar to table based generators with the exception that the majority of the instruction, operand and data selection reside in complex
