In the tran command (tran 10m 10 1) you asked it to strobe at 1 
second intervals.  So, no matter what the signal, you get 
samples 1 second apart.

If you add "trace all" to the tran command you will see all of 
the samples, which should produce a smoother waveform.

How it works is a throwback to when people actually looked at 
ASCII plots.  It needs to change to make "trace all" the 
default, and have the strobe interval require a keyword "strobe" 
like spectre does.

The actual time stepping is determined internally.  There will 
be extra steps internally if needed to get a proper simulation, 
but they are not displayed unless you ask for them.
