-# ☁️ Azure Student Developer Pack Guide for AgentIC
-
-Since your local PC is overheating, moving to Azure is the perfect solution. With the **Microsoft Azure Student Pack**, you get **$100 credit** and free access to specific services.
-
-This guide will help you create a **Virtual Machine (VM)** to run OpenLane and AgentIC without burning your laptop.
-
-## 1. Create the Virtual Machine (VM)
-The "hectic" part is the OpenLane build process (compiling 30,000 transistors!).
-
-1.  Log in to the [Azure Portal](https://portal.azure.com).
-2.  Click **"Create a resource"** > **"Virtual Machine"**.
-3.  **Basics Tab**:
-    *   **Subscription**: Azure for Students.
-    *   **Resource Group**: Create new (e.g., `rg-agentic`).
-    *   **Virtual Machine Name**: `vm-agentic`.
-    *   **Region**: Pick one close to you (e.g., East US).
-    *   **Image**: **Ubuntu Server 22.04 LTS - x64 Gen2**.
-    *   **Size**: **Standard D4s v3** (4 vCPUs, 16 GiB memory).
-        *   *Note:* This costs about ~$0.18/hour. Since you have $100 credits, you can run this for ~500 hours.
-        *   *Important:* Remember to **STOP** the VM when you aren't using it to save credits!
-4.  **Administrator Account**:
-    *   **Authentication type**: SSH public key.
-    *   **Username**: `azureuser`.
-    *   **Key source**: Generate new key pair.
-5.  **Review + create** > **Create**.
-    *   Download the private key (`.pem` file) when prompted. Keep it safe!
-
-## 2. Connect to the Cloud
-1.  Open your local terminal (Git Bash or WSL).
-2.  Move the key to a safe place and secure it:
-    ```bash
-    mv ~/Downloads/vm-agentic_key.pem ~/.ssh/
-    chmod 400 ~/.ssh/vm-agentic_key.pem
-    ```
-3.  Connect (replace `YOUR_VM_IP` with the Public IP from Azure Portal):
-    ```bash
-    ssh -i ~/.ssh/vm-agentic_key.pem azureuser@YOUR_VM_IP
-    ```
-
-## 3. Install the Environment (One-Time Setup)
-Copy and paste this block into your Azure SSH terminal to install everything:
-
-```bash
-# Update and Install Docker
-sudo apt-get update
-sudo apt-get install -y docker.io python3-pip python3-venv git make
-sudo usermod -aG docker $USER
-newgrp docker
-
-# Setup OpenLane
-git clone https://github.com/The-OpenROAD-Project/OpenLane.git ~/OpenLane
-cd ~/OpenLane
-# This download is heavy (~2GB), but it runs on Azure's fast internet!
-make pull-openlane 
-
-# Get your AgentIC code
-# (You can clone your repo, or we create a fresh one)
-mkdir -p ~/AgentIC
-```
-
-## 4. Solving the "Thinking" Heat (The LLM)
-Running Ollama (DeepSeek) locally is what heats up your GPU. On an Azure CPU VM, it will be slow.
-**Recommendation:** Use the **DeepSeek API** instead. It costs pennies and offloads the "brain" work to DeepSeek's servers.
-
-1.  Get an API Key from [platform.deepseek.com](https://platform.deepseek.com).
-2.  On the Azure VM, export it:
-    ```bash
-    export OPENAI_API_KEY="sk-..."  # Your DeepSeek Key
-    export OPENAI_API_BASE="https://api.deepseek.com"
-    export LLM_MODEL="deepseek-chat"
-    ```
-
-## 5. Running the Flow
-Now, your laptop stays cool while Azure does the work.
-
-```bash
-# On Azure VM
-cd ~/AgentIC
-python3 main.py build --name cloud_chip --desc "An 8-bit counter"
-```
-
-## 6. Retrieving the Result
-When finished, download the GDS file to your laptop to view it:
-
-```bash
-# On Local Laptop
-scp -i ~/.ssh/vm-agentic_key.pem azureuser@YOUR_VM_IP:~/AgentIC/cloud_chip.gds ./
-```

-   - Use `repeat(25) @(posedge clk);` minimum before checking ANY output.
-   - If there's a `done` or `valid` signal, use `while(!done) @(posedge clk);`
-2. **Race Conditions**: Add `#1` delays after clock edges before sampling.
-3. **Reset**: Ensure reset is held for at least 4 clock cycles.
-4. **Between Tests**: Wait for FSM to return to IDLE with `repeat(10) @(posedge clk);`

-  - If the design is an NPU or Processor, do NOT replace complex logic with simple static assignments.
