SignalTap II version 13.0.1 Status Flags do not get set.

I have a state machine. The counters work but the status flags do not. Ex. code below.

if (condition1)

begin

set f1;

goto ST2;

end

else

begin

reset c1;

goto ST1;

end

if (condition2)

begin

set f2;

goto ST3;

end

else

goto ST2;

if (c1==2)

begin

trigger;

goto ST1;

end

else if (condition3)

begin

increment c1;

goto ST3;

end

Neither will be get set to a 1. Always 0.

Anyone know why the flags don't get set?

Also I found that one does not have to reset the counter. Simply by hitting the

Run Analysis button seems to reset everything.

    How do you know the flag is not set? You don't read it, but just write, in your state machine.

    Actually, you can setup the initial value of counter and flag when acquisition is started. By default, they are 0s.

    I remember there were problems of changing names and initial values using that table windows in a few versions. I wonder if this could be related.
