Basic introduction and simple engineering application of GAL20V8QS-20LVI

GAL20V8QS-20LVI is a programmable logic device (PLD) manufactured by Lattice Semiconductor. It belongs to the GAL (Generic Array Logic) family and offers 20 inputs, 8 outputs, and operates at a speed grade of 20ns.

Application Scenario:

In educational projects and simple digital systems, GAL20V8QS-20LVI can be utilized to implement basic combinatorial and sequential logic functions, such as logic gates, multiplexers, decoders, and state machines.

Experiment Setup:

To understand the functionality of GAL20V8QS-20LVI and its application in a simple project, follow these steps:

1. Programming:

Using a GAL programmer, such as the Lattice ispLEVER software suite, program the desired logic functions into GAL20V8QS-20LVI. Define the input and output pins and specify the truth table or equations for the desired logic operation.

2. Breadboard Setup:

Connect power (VCC and GND) and configure input switches or push buttons to provide input signals to the GAL20V8QS-20LVI. Connect LEDs or other output indicators to observe the output states.

3. Basic Logic Functions:

Implement basic logic functions, such as AND, OR, NOT, XOR, using GAL20V8QS-20LVI. Configure the GAL to perform these functions based on the programmed logic equations.

4. Combinatorial Logic:

Construct combinatorial logic circuits, such as adders, subtractors, and comparators, using GAL20V8QS-20LVI. Connect input switches to represent binary numbers and observe the output LEDs to verify the logic operation.

5. Sequential Logic:

Explore sequential logic circuits, such as flip-flops, registers, and counters, using GAL20V8QS-20LVI. Design and simulate simple state machines or sequential circuits and observe the output changes based on input transitions.

Considerations:

When working with GAL20V8QS-20LVI, keep the following considerations in mind:

- Programming: Ensure the correct configuration files and fuse settings are used during programming to avoid programming errors.

- Pin Configuration: Double-check the pin assignments and connections to ensure proper interfacing with external components.

- Timing Constraints: Take into account the propagation delay and setup/hold time requirements of the GAL20V8QS-20LVI when designing sequential logic circuits to avoid timing violations.

- Testing and Debugging: Test each logic function thoroughly and use simulation tools if available to verify the correctness of the programmed logic before hardware implementation.

- Documentation: Keep detailed documentation of the logic equations, pin assignments, and circuit diagrams for future reference and troubleshooting.
