Component Specification Parser

A Python system that parses component datasheets and determines compatibility based on operating voltage and temperature ranges.

Project Structure

• component_parser.py - Main parser implementation
• test_component_parser.py - Test suite
• Task example files/ - Sample datasheet files for testing the parser
  • Contains text-extracted datasheets from various electronic components
  • Used to verify parser accuracy with real-world examples
  • Each file contains voltage and temperature specifications in different formats

Requirements

• Python 3.x (no additional packages required)

Usage

python component_parser.py [-v]  # -v for verbose output

When prompted, enter:

• Operating voltage (V)
• Operating temperature (°C)

The program will display all compatible components.

Running Tests

python test_component_parser.py

How It Works

1. Reads component datasheet files (.txt)
2. Uses regular expressions to parse:
   • Voltage ranges (e.g., "3.15V to 3.45V Operation")
   • Temperature ranges (e.g., "-40°C to +85°C")
3. For multiple ranges in a file:
   • Uses the range if all are identical
   • Sets to None if ranges differ
4. A component is compatible if both voltage and temperature are within range

Implementation Details

• Regular expressions handle various text formats:
  • Direct ranges: "3.15V to 3.45V"
  • Prefixed ranges: "Supply voltage: 2.7V to 5.5V"
  • Suffixed ranges: "3.15V to 3.45V Operation"
• Handles both Latin-1 and UTF-8 encodings
• Validates ranges for reasonable values
• Comprehensive test coverage with unittest

Assumptions

• Voltage specifications contain 'V' or 'v' unit
• Temperature specifications in Celsius (°C, C)
• When multiple ranges exist, they must be identical to be valid
• Voltage and temperature ranges are within reasonable bounds for electronic components
