Q$7.$ Design a shift register using the PLC Fiddle Playground. Additional Guidance: A shift register may require chaining memory

$2$B$.$ Boolean Logic bits in a sequence that shifts upon each activation of an input.

Circuit Design

Be sure to label your images clearly, so I can identify which section they

More Notes and suggestions.

Testing Strategy

$1.$ Reset register to a known state

$2.$ Input a pattern of $1$ s and $0$ s

$3.$ Observe bits shifting through the register

$4.$ Verify proper timing and data retention

Common Issues and Solutions

$-$ Race Conditions: Update bits in reverse order

$-$ Data Loss: Use intermediate storage

$-$ Timing Issues: Ensure edge detection works properly

Best Practices for All Implementations

$1.$ Documentation

$-$ Comment on your ladder logic

$-$ Explain the purpose of each rung

$-$ Document any assumptions

$2.$ Testing

$-$ Create a test plan before implementation

$-$ Test edge cases

$-$ Verify timing behavior

$3.$ Troubleshooting

$-$ Use PLC Fiddle's simulation features

$-$ Monitor bit states during the operation

$-$ Break complex problems into smaller parts

$4.$ Memory Usage

$-$ Use consistent naming conventions

$-$ Document memory bit assignments

$-$ Avoid unnecessary complexity

A shift register moves bits through a series of storage locations, shifting one position each time it's triggered.

Components Required

$-$ Data input $(10)$

$-$ Shift trigger input $($I$1)$
