How do you perform in T-spice a set of corner simulations over process, voltage and temperature (PVT)? In my mind (ideally), this would be a table format, where each line defines one simulation run. Thanks for any hint.

For corner simulations, you can use the command .alter to your netlist to switch between different corners. You can use .del lib and .lib to unload the old corner and reload the new corner. The following example is copied from the T-Spice user guide.

** Load typical corner
.lib bsim3model.md typical

** Load fast corner
.alter
.del lib bsim3model.md typical
.lib bsim3model.md fast

** Load slow corner
.alter
.del lib bsim3model.md fast
.lib bsim3model.md slow

If you have S-Edit, there is a Corner Simulations option in the Setup>SPICE Simulation settings which will give you the table view you are looking for to setup multiple corner simulations.
