Tolerate Glitches on Bus Transitioning between Stable States

This example shows how to use Verilog inertial delay modeling to avoid dynamic hazards on a bus changing from one stable state to another, such as when caused by differences in delays of individual bits.

References to Titles/Headings in reStructuredText (RST)

In RST, one can easily refer to a title/heading (or more generally to a section start, which the heading really is) by using its text as a reference. For example:

... some text and then reference to `My Heading`_ ...

My Heading
