 oscillations on a gate input faster than that gate's
delay will produce "unknown" on the output rather than propagating the
oscillations.

<li><b>Technology Files:</b> Use this to install additional
user-defined delay/area models for gates in addition to the built-in
model.  Gate delay files have a ".gdf" extension.

<li><b>Error Handling:</b> Use this feature to tell TkGate what to do
with simulator errors and warnings. One of the following levels can be
selected:
