I would like to see how the phases of each inverter stage in the ring changes with time. If i connect odd number of inverter stages and probe the last stage with a scope, I am getting this error "Cannot solve algebraic loop involving 'untitled/Logical Operator' because it consists of blocks that cannot be assigned algebraic variables, such as blocks with discrete-valued outputs, blocks with non-double or complex outputs, Stateflow blocks, or nonvirtual subsystems. Consider breaking the algebraic loop. For example, add a delay or a memory block to the loop."
 

I would recommend you attach a snapshot of the diagram that you're trying to simulate, as well to post the exact error message reported.
 

According to the error message you are trying to build a ring oscillator with delay-less inverters. That's not possible.
