VHDL Modeling Styles

Description

This simulation shows three ways to describe the same circuit in VHDL: dataflow (concurrent signal assignments), structural (component instantiation), and behavioral (process statements). Compare how each approach describes a 2-to-1 multiplexer.

Learning Objectives

Bloom Level: Analyze (L4)

  • Compare the three VHDL modeling styles
  • Identify when to use each modeling approach
  • Analyze how the same function maps to different descriptions
  • Understand the relationship between style and abstraction level

How to Use

  1. View all three columns showing the same circuit described differently
  2. Click on a column header to expand that style's details
  3. Toggle inputs A, B, Sel to see how each model evaluates
  4. Observe that all three produce identical outputs
