As the screening task to get selected, you need to figure out the various problems faced while installing eSim-2.5 on Ubuntu 25.04 and above systems. Please ensure that you use the technologies mentioned. Please follow the submission procedure and go through the evaluation criteria carefully while submitting the task.

Description:
The task involves to figure out the dependency issues while installing eSim 2.5 on Ubuntu 25.04 and fix at least one of the issues.

Steps:

1. You need to have Ubuntu 25.04 installed on your system(You may use a Virtual Box).
2. Download and try installing eSim-2.5 on Ubuntu 25.04 machine from here.
3. List down the problems you would be facing while installing eSim, for example you may get stuck while eSim installs llvm.
4. Look into the install-eSim.sh script and try making some changes to fix an error.
5. If the problem is not fixed, you may comment out some part of the script so that you may move on to the next bug
6. You may need to refer to the various resources.
7. Create a well documented report of the problems you have faced while installing eSim and mention the steps in detail and the measures you have taken to fix them

Note: Fixing at least one issue is desirable

Technologies to be used:

1. Bash Script

2. Python

3. eSim

4. Spoken Tutorial on Git

5. Ubuntu 25.04 OS

Submission Procedure:

1. Create a GiHub Account
2. Fork the eSim Repository
3. Checkout to the installer branch
4. Commit the code files here
5. Share back the link for your forked repository and the documented report by the below-mentioned deadline by mail to contact-esim@fossee.in. Inform us by sending a mail with the subject line "eSim Semester Long Internship Autumn 2025 Submission Task 4" with the submission task details.

Evaluation criteria:

1. Quality of documentation

(For example – On visiting your repository, any user should understand the details of the bugs/issues, methodology, steps involved in fixing the bugs, etc.)

2. Number of issues reported

3. Number of issues fixed

4. The difficulty level of the problems fixed(For example: A dependency issue which interrupts the installation of the main GUI of eSim will be given higher weightage than those which interrupts the installation of smaller blocks like NgVeri, etc.)

Problem Statement:

eSim is an open-source EDA tool for circuit design, simulation, analysis, and PCB design. It integrates several external tools and libraries to provide a seamless environment for engineers and researchers. Managing these tools manually can be tedious, especially when considering updates, compatibility, and user-specific configurations.

The goal of this task is to design an "Automated Tool Manager” for eSim(preferably in python) that automates the installation, configuration, update, and management of external tools and dependencies.

Below are the requirements for the screening tasks. The task submission needs to meet any 2 of the requirements listed below.

Requirements:

1. Tool Installation Management:
   • The manager should be able to download and install required external tools (e.g., Ngspice, KiCad, etc.) automatically.
   • Ensure compatibility with the system environment (Linux/Windows).
   • Handle version control to ensure the correct versions of tools are installed.
2. Update and Upgrade System:
   • Design a system that checks for updates for the external tools and libraries.
   • Implement functionality for the user to update these tools with minimal manual intervention.
3. Configuration Handling:
   • Automate the configuration of the installed tools based on user settings or predefined settings.
   • Handle path management and environment variable settings so that the tools work seamlessly with eSim.
4. Dependency Checker:
   • Ensure that all necessary dependencies for the installed tools are checked and managed.
   • Provide feedback to the user if certain dependencies are missing or incompatible.
5. User Interface:
   • Provide a simple, user-friendly command-line or graphical interface for managing the tools.
   • Allow the user to view installed tools, versions, and any updates available.
   • Provide a log of actions taken (e.g., installations, updates, errors).
6. Additional Features (Optional):
   • Cross-platform support (Linux/Windows/Mac).
   • Integration with popular package managers (e.g., apt, Homebrew, Chocolatey) to streamline tool management.

Deliverables:

1. Design Document: A detailed document describing the architecture of the Automated Tool Manager. This should include the overall design, module breakdown, and how the different components (installation, updates, configuration, etc.) interact.

2. Code Implementation:

   • A basic prototype or proof-of-concept code that demonstrates at least tool installation and version checking.

   • You may use any language or platform for the implementation (Python, Shell script, etc.).

3. Instructions for Execution: Provide clear steps on how to run and test the prototype. This should include installation instructions for any dependencies required for your tool.

4. Presentation (Optional): A short video or presentation (5-10 minutes) explaining your approach, design choices, and a demo of your tool manager.

Evaluation Criteria:

• Functionality: How well the tool manager achieves the desired functionality (installation, updates, configuration).

• Design: Clarity and efficiency of the design, ease of use, and modularity.

• Documentation: The clarity of the design document and code documentation.

• Creativity: Additional features or unique approaches taken to solve the problem.

• Code Quality: Readability, structure, and use of best practices in coding.

Submission Guidelines:

• Submit your design document, code, and instructions as a GitHub repository link.
• Ensure that the created repository is private and give access to the following github id: https://github.com/Eyantra698Sumanto
• Share back the link for your forked repository and the documented report by the below-mentioned deadline by mail to contact-esim@fossee.in. Inform us by sending a mail to contact-esim@fossee.in with the subject line "eSim Semester Long Internship Autumn 2025 Submission Task 5" with the submission task details.
