WebTransparent latches will appear if you write a combinational process or always block where an output is not assigned under all possible input conditions. In other words, it is possible for one of the inputs to change without affecting the output. In synthesis jargon, this is known as incomplete assignment. Here's a simple decoder with a problem:
