- References to other manuals
  See the Development System Reference Guide for more information.
- Emphasis in text
  If a wire is drawn so that it overlaps the pin of a symbol, the two nets are not connected.
Square brackets "[ ]" indicate an optional entry or parameter. However, in bus specifications, such as bus [7:0], they are required.
