After studying the content of these projects, you will be able to:

• Explain the specifications and characteristics of the standard combinational logic blocks: multiplexers (or data selectors), de-multiplexers (or data distributors), decoders, encoders, hexadecimal to seven-segment LED displays adapters, code converters, etc. Specifications include concepts like: symbol, truth table and functionality, internal design, expandability, and commercial chips of similar characteristics.

• Explain the functionality of the enable input that is available in most of these standard circuits.

• Explain the concepts of flat and hierarchical designs and implement simple projects in VHDL involving a single file (flat) using structural (plan A) or behavioural (plan B) approaches.

• Explain how to chain or expand such devices to implement a larger one, for instance, how to connect several MUX_4 to obtain a MUX_16.

• Implement standard circuits targeted at a given PLD (CPLD or FPGA) using VHDL and synthesis and simulation EDA tools. Explain the VHDL design flow.

• Find datasheets of classic logic circuits from different technologies.

• Explain how to interface switches to encoders.

•  Explain how to interface LEDs and seven-segment display to decoder outputs.
