Version control for PCB projects in PCB Design - Dashboard Guide

Dashboard Mode - Version control for PCB projects

Goal

Track and analyze version changes in PCB projects to understand progress, identify frequent updates, and monitor design stability over time.

Sample Data

Project	Version	Date	Changes Count	Designer	Status
AlphaBoard	v1.0	2024-01-10	5	Alice	Released
AlphaBoard	v1.1	2024-02-15	3	Bob	Released
BetaBoard	v0.9	2024-01-20	8	Charlie	In Progress
BetaBoard	v1.0	2024-03-05	2	Charlie	Released
GammaBoard	v1.0	2024-02-01	10	Alice	Released
GammaBoard	v1.1	2024-04-10	4	Bob	In Progress

Dashboard Components

• KPI Card: Total Versions Released
  Formula: Count of rows where Status = 'Released'
  Result: 4
• KPI Card: Average Changes per Version
  Formula: Average of Changes Count column
  Result: (5+3+8+2+10+4)/6 = 5.33
• Bar Chart: Versions per Project
  X-axis: Project
  Y-axis: Count of Versions
  Data: AlphaBoard=2, BetaBoard=2, GammaBoard=2
• Line Chart: Changes Over Time
  X-axis: Date
  Y-axis: Changes Count
  Lines: One per Project
  Shows how changes count varies by version date
• Table: Version Details
  Columns: Project, Version, Date, Changes Count, Designer, Status
  Shows all version records for detailed view

Interactivity

Filter by Project: Selecting a project updates all charts and the table to show only that project's versions.

Filter by Status: Choosing 'Released' or 'In Progress' filters the KPIs, charts, and table accordingly.

Date Range Filter: Limits the data shown in charts and table to versions within the selected date range.

Self Check

If you add a filter for Project = 'BetaBoard', which components update?

• KPI Cards update to show only BetaBoard versions and average changes.
• Bar Chart updates to show only BetaBoard with count 2.
• Line Chart shows changes over time only for BetaBoard.
• Table filters to show only BetaBoard version details.

Key Result

Dashboard showing PCB project version counts, changes over time, and detailed version info with filters by project and status.

Practice

1. What is the main purpose of using version control in PCB projects?

easy

A. To improve the electrical performance of the PCB

B. To increase the speed of PCB manufacturing

C. To reduce the cost of PCB components

D. To track changes and manage different versions of PCB designs

Solution

1. Step 1: Understand version control basics

   Version control systems keep track of changes made to files over time.

2. Step 2: Apply to PCB projects

   In PCB design, version control helps manage different design iterations and collaborate safely.

3. Final Answer:

   To track changes and manage different versions of PCB designs -> Option D

4. Quick Check:

   Version control = Track changes [OK]

Hint: Version control means tracking changes over time [OK]

Common Mistakes:

• Confusing version control with manufacturing speed
• Thinking it reduces component cost
• Assuming it improves electrical performance directly

2. Which of the following is the correct command to commit changes in a Git-based version control system for PCB files?

easy

A. git push -m "Update PCB layout"

B. git commit -m "Update PCB layout"

C. git add -m "Update PCB layout"

D. git merge -m "Update PCB layout"

Solution

1. Step 1: Identify the commit command

   The command to save changes with a message is git commit -m "message".

2. Step 2: Check other commands

   git push uploads commits, git add stages files, git merge combines branches.

3. Final Answer:

   git commit -m "Update PCB layout" -> Option B

4. Quick Check:

   Commit = git commit -m [OK]

Hint: Commit changes uses 'git commit -m' with a message [OK]

Common Mistakes:

• Using git push instead of git commit for saving changes
• Adding -m flag to git add which doesn't accept it
• Confusing merge with commit

3. Given the following Git commands executed in order for a PCB project:

git add design_v1.kicad_pcb
git commit -m "Initial design"
git checkout -b feature_update
git add design_v2.kicad_pcb
git commit -m "Update design"
git checkout main
git merge feature_update

What will be the state of the main branch after the merge?

medium

A. It will contain both design_v1.kicad_pcb and design_v2.kicad_pcb changes

B. It will only have design_v1.kicad_pcb changes

C. It will only have design_v2.kicad_pcb changes

D. It will be empty with no design files

Solution

1. Step 1: Analyze branch creation and commits

   The feature_update branch adds design_v2.kicad_pcb and commits it separately from main.

2. Step 2: Understand merge effect

   Merging feature_update into main brings design_v2.kicad_pcb changes into main, keeping design_v1.kicad_pcb too.

3. Final Answer:

   It will contain both design_v1.kicad_pcb and design_v2.kicad_pcb changes -> Option A

4. Quick Check:

   Merge combines changes from both branches [OK]

Hint: Merge adds feature branch changes to main branch [OK]

Common Mistakes:

• Thinking merge replaces main branch content
• Assuming only feature branch files remain
• Ignoring initial commit on main branch

4. You tried to commit changes to your PCB project but got this error:
error: pathspec 'design_v3.kicad_pcb' did not match any files
What is the most likely cause?

medium

A. The Git repository is corrupted

B. The commit message is missing

C. The file design_v3.kicad_pcb was not added to staging area

D. You are on the wrong branch

Solution

1. Step 1: Understand the error message

   The error says the file path was not found in the staging area for commit.

2. Step 2: Identify missing step

   Files must be added with git add before committing.

3. Final Answer:

   The file design_v3.kicad_pcb was not added to staging area -> Option C

4. Quick Check:

   File must be staged before commit [OK]

Hint: Add files with git add before committing [OK]

Common Mistakes:

• Assuming commit message is the cause
• Thinking repository is corrupted
• Believing branch affects file staging

5. You want to keep track of multiple PCB design versions and collaborate with your team. Which combination of version control practices is best to ensure safe collaboration and clear history?

hard

A. Use branches for features, commit often with clear messages, and merge with pull requests

B. Commit only once after all changes, avoid branches, and overwrite files directly

C. Use branches but never merge, keep all changes in separate branches

D. Avoid committing frequently and share files via email instead

Solution

1. Step 1: Identify best collaboration practices

   Using branches allows isolated work; frequent commits with messages track progress.

2. Step 2: Understand merging and pull requests

   Merging with pull requests reviews changes before integration, preventing conflicts.

3. Final Answer:

   Use branches for features, commit often with clear messages, and merge with pull requests -> Option A

4. Quick Check:

   Branches + commits + pull requests = safe collaboration [OK]

Hint: Branch, commit often, merge with pull requests [OK]

Common Mistakes:

• Committing only once losing history
• Avoiding merges causing isolated work
• Sharing files outside version control
