PLA Architecture

Description

This simulation demonstrates a Programmable Logic Array (PLA) with both programmable AND and OR arrays. Click crosspoint connections to define product terms and sum-of-products outputs.

Learning Objectives

Bloom Level: Apply (L3)

  • Configure product terms in the AND array
  • Connect product terms to outputs in the OR array
  • Evaluate PLA outputs for given inputs
  • Understand the two-level AND-OR structure

How to Use

  1. Set inputs A, B, C by clicking their toggle buttons
  2. Click crosspoints in the AND array to include/exclude literals
  3. Click crosspoints in the OR array to connect product terms to outputs
  4. Click Evaluate to compute outputs based on current inputs
  5. Observe which product terms activate and which outputs go high
