The state machine appears to have a bug.? The nominal output amplitude is 1mV rather than 1V, so the output equations must be multiplied by 1k.? For example:
.output (2) (V(1)<.5)*1k
.output (3) (V(1)>.5)*1k
.output (4) state*1k
Also (not bugs):
The .output are voltage sources, but are considered to be floating, thus they must be loaded with a resistor or other device that provides a path to ground.
The triptdt parameter only affects output edges that are triggered by state changes, not output edges that are dependent only on inputs.

Hello,
I just got a message from Mike that LTspiceXVII is now relased.
Mike, thank you for the continuous improvements of LTspice during the last 17 years.
?
The advertised features from this webpage are below.
LTspice?XVII
LTspice XVII?is?partial rewrite of LTspice IV with a modern graphics library for native multi-monitor support. XVII also includes:
- 64-bit support
- UNICODE (use any character of any living language)
- New device equations (IGBT, soft recovery, and an arbitrary state machine)
- Improved GUI: Editors for most SPICE syntax commands
- Extensions to Microsoft Windows for schematic thumbnail previews
LTspice XVII runs on 32- or 64-bit editions of Windows 7, 8 or 10. Windows XP is not supported. Windows XP users can run LTspice IV, which will still be available in observance of Linear Technology Corporation's zero obsolescence tradition.
Best regards,
Helmut
