Let's break this down into manageable steps using Python (you can adapt this logic to other languages too—just adjust the syntax to match your tool of choice):

1. First, Handle Bus/Vector Bit Splitting #

First, we need a helper function to expand those bus/vector notations into individual bits. For example, if you have an element like data[7:0], this function will turn it into ["data[7]", "data[6]", ..., "data[0]"], while leaving single-bit elements like ctrl[1] or regular elements like enable untouched.

import re

def split_bus_bits(element):
    # Match range notation like "name[start:end]"
    bus_range_match = re.match(r'(\w+)\[(\d+):(\d+)\]', element)
    # Match single-bit notation like "name[bit]"
    single_bit_match = re.match(r'(\w+)\[(\d+)\]', element)
    
    if bus_range_match:
        name, start, end = bus_range_match.groups()
        start_int = int(start)
        end_int = int(end)
        # Handle both ascending (0:7) and descending (7:0) ranges
        step = 1 if end_int > start_int else -1
        return [f"{name}[{i}]" for i in range(start_int, end_int + step, step)]
    elif single_bit_match:
        return [element]
    else:
        # Regular element with no bus bits
        return [element]

2. Process Each Individual List #

For each of your 6 lists, we’ll do three key things: expand bus elements, wrap every element in double quotes, then wrap the whole list in parentheses.

def process_single_list(input_list):
    # Expand all bus elements first
    expanded_elements = []
    for elem in input_list:
        expanded_elements.extend(split_bus_bits(elem))
    # Wrap each element in double quotes
    quoted_elements = [f'"{elem}"' for elem in expanded_elements]
    # Join elements with commas and wrap in parentheses
    return f"({', '.join(quoted_elements)})"

3. Merge All Processed Lists into One Big String #

Take the 6 processed list strings and join them together (we’ll use commas as separators—swap this for spaces or another delimiter if you need it):

# Replace these with your actual 6 lists
list1 = ["data[7:0]", "enable"]
list2 = ["addr[3:1]", "reset"]
list3 = ["ctrl[2]", "status[0]"]
list4 = ["clk"]
list5 = ["rx[1:0]"]
list6 = ["tx[4:2]"]

# Process each list
processed_lists = [
    process_single_list(list1),
    process_single_list(list2),
    process_single_list(list3),
    process_single_list(list4),
    process_single_list(list5),
    process_single_list(list6)
]

# Combine into the final big string
final_result = ', '.join(processed_lists)
print(final_result)

Example Output #

Running the code above will produce exactly what you need:

("data[7]", "data[6]", "data[5]", "data[4]", "data[3]", "data[2]", "data[1]", "data[0]", "enable"), ("addr[3]", "addr[2]", "addr[1]", "reset"), ("ctrl[2]", "status[0]"), ("clk"), ("rx[1]", "rx[0]"), ("tx[4]", "tx[3]", "tx[2]")

Quick Customization Tips #

• If your bus notation uses angle brackets (name<7:0>) instead of brackets, just adjust the regex patterns in split_bus_bits.
• If you want a different separator between the parenthesized lists (like spaces instead of commas), change ', '.join(processed_lists) to ' '.join(processed_lists).
• If you need to handle edge cases (like non-numeric bus indices), you can add extra checks to the helper function.
