Please don't use those silly SMS-style abbreviations on this site. If you don't want to type things in plain English, then please go elsewhere to type that gibberish.

It's hard to tell what you mean with your comment. You can't do serious MCU circuit development without (A) a voltmeter, (B) an oscilloscope of a bandwidth at least twice that of the fastest clock used in your system, and better 10x that rating, and (C) a logic analyzer or perhaps a real-time emulator. Other instruments, e.g. pulse generators, counters, and signal generators are also quite helpful and should also be capable of frequencies in the range of 2.5x to 10x (or more) of the fastest signals in your system.

The ALL-11 is a device programmer, as once was popular for programming MCU's, EPROMS, and PLD's. It is not capable of full testing of any IC, as it only tests functionality and not timing. It does not distinguish between open collector or open drain outputs and totem pole outputs including tristate outputs. It doesn't know how to differentiate between slightly similar devices, e.g. 74125 and 7400 or 74126 and 7408. It probably doesn't differentiate between 74163 and 74161 either. There are, of course, many other devices that "fall through the cracks" too.

I'm not clear at all as to what any of this has to do with the original query, regarding (erroneously, perhaps) "testing" of circuits and "free" software.

Circuit testers need to have response times of device testers, i.e. delays not exceeding 100 ps in order to verify that the device timing is withing specified limits. They also need to have loads commensurate with those needed to verify the specified currents at inputs and outputs are met. The All-11 doesn't have these features.

Perhaps you need to clarify your goals a bit further.
