Screening Task 5: Tool manager (CSE and related fields)

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:
