I refer my question to veriloga voltage sources, generally full-swing, but not only.
What is a "veriloga voltage source"?? Do you mean a voltage source from Annex E, which tells you how to instantiate voltage sources from a Spice simulator? In that case, it's your job to pick a well-behaved source. Eg, PWL is continuous but its derivatives are not, but that's not Verilog-A's fault.
Otherwise, you can write a voltage source directly in Verilog-A, and it's completely in your hands how you write the output voltage as a function of time.
