VHDL: Programming by Example

CHAPTER 10

VHDL Synthesis

In this chapter, we focus on how to write VHDL that can be read by synthesis tools. We start out with some simple combinational logic examples, move on to some sequential models, and end the chapter with a state machine description.

All of the examples are synthesized with the Exemplar Logic Leonardo synthesis environment. The technology library used is an example library from Exemplar Logic. All of the output data should be treated as purely sample outputs and not representative of how well the Exemplar Logic tools work with real design data and real constraints.
