Animate: Program and data flow

[gs99]

Is there a way to single step through Program and data flow?

Single Step will execute one statement in the test script. You may need to edit the test script if it uses repeats.

Note: "tick, output, tock, output;" is one statement, "tick, output; tock, output;" is two.

When I Single Step with option Animate: “Program and data flow”, many smaller steps are shown within each Step.

I’d like to single step through these smaller steps, to get a better appreciation of what is being done.

As I said, you will need to edit the test script. Single step works one statement at a time. Statements are terminated by ';'. Use them instead of ','.

Within a “Single Step” statement, there may be many steps displayed when “Program and data flow” is selected. In some cases, I counted 30 steps, where values are being changed.

These are the smaller steps I’d like to see one at a time.

Example where this occurs, please. Which .tst file, what line number.

If you are talking about individual gate level changes -- gate A changes causing gate B to change causing ... -- there is no way to single step that.

Example: CPU.tst.
set instruction %B0011000000111001, // @12345
tick, output, tock, output;
there are about 8 steps/changes shown.

I’ve not seen an explanation of this Animate option, so I don’t know what these smaller steps are called.
There’s no benefit to this option if we can’t see them one at a time.
It appears to be the equivalent of single-stepping lines of code in a computer program.
I thought it may help to reveal some logic errors.

The best you can do is to change all the
    tick, output, tock output;
lines to
    eval; tick, output; tock, output;
(Note ','s and ';'s)

And after the animation plays you can see what changed by scrolling; the changed values are blue.
