State machine and unsigned signal

I hope this helps . I have a few problems with a fairly simple state machine I made. No matter what I do, the signal startS1, startS2, enS and mS always stays unsigned in simulation even when I hit the reset button and I can't figure out why. There's a component in the mix, but I did test the component and it works perfectly. I hope you can help me! , Add RESET to your process sensitivity list.

State-machine : How to change state without external event (transient state)?

fixed the issue. Will look into that further In a state machine, next state is a combinatorial logic function of both input and current state.
In the case you are describing, the same cause (Initialized state) seems to be able to trigger two different effects (either InProgress or Error state). I guess that there is a hidden input whose value makes the difference. I also guess that this input is received during transition from Uninitialized to Initialized.
Uninitialized -> Successfully initialized -> InProgress -> Done
             \
              `-> Failed Initialization -> Error

I wish did fix the issue. PEBCAK. I should have written the name of the signal without the on prefix:
signal: thingy.somethingHappened

State machine transitions to impossible state on Signal Tap

around this issue This is almost certainly a timing issue. I'm guessing that sclk is not synchronous to clk - probably it's connected directly to a device input pin.
The problem is this piece of code:
(...)
else if (sclk)
   next_state = BIT_CHANGE;
else 
   next_state = MISO_OUT;

What’s the best way to pass a signal from ASP.NET app on one machine to .NET Windows Service on another machine?

In a state machine process is there a difference if I state specifically that the state stays the same?
