The same device with a short pulse applied produces no output
change.
However, if TPWRT is assigned a numerical value (1 or 2 for
this example), then the device outputs a glitch.

The delay line primitive is the only simulator model that can
propagate any width pulse applied to its input. Its function is to
skew the applied stimulus by some constant time value. For
example:
TPLHTY=10
20 40 30 50
TPHLTY=10
(TPWRT not set)
TPLHTY=10
20 22
TPHLTY=10
(TPWRT not set)
TPLHTY=10
20 22 30 32
TPHLTY=10
TPWRT=1
