SVG Symbol Generator

A Python script that generates SVG symbols from pin list files.

Usage

python svg_generator.py --input <pin_list_file> --output <output_svg_file> [--name SYMBOL_NAME]

If --name is not provided, the symbol will have no title text.

Pin List Format

Each line in the pin list file should follow this format:

name direction type polarity

Where:

• name: Pin name (e.g., clk, addr, dout)
• direction: Either input or output
• type: Either pin or bus
• polarity: Either positive or negative

Lines starting with # are treated as comments and ignored.

Example

python svg_generator.py --input example_sram.input.txt --output sram_symbol.svg --name "SRAM"

This will generate an SVG symbol for an SRAM using the pin definitions in example_sram.input.txt. The output file will be automatically placed in the Result/ directory.

Features

• Automatic symbol sizing based on number of pins
• Clock pins get triangle indicators
• Negative polarity pins/buses get circle indicators
• Bus pins get bus notation
• Input pins on the left, output pins on the right
• Clean, professional SVG output
• Automatic output placement in Result/ directory

Pin List Example

# SRAM pins
clk input pin positive
cen input pin negative
addr input bus positive
din input bus positive
dout output bus positive
