No SDO file produced for Timing Simulation

EDA tools are meant to be 3rd-party-tools such as modelsim for simulation.

As for synthesis quartus does that itself.

quartus simulator if available is too basic compared to modelsim and Intel(Altera) is so embarrassed about it and stopped it.

As to timing simulation I haven't done it all my life. I am happy with functional simulation + timing analysis using correct constraints.

For some large projects timing simulation could take days to finish-just to give an idea.

Timing simulation is favoured for very small safety critical projects.
