# Virtuoso Schematic MCP
This is a focused MCP server for interacting with Cadence Virtuoso schematics.
It provides tools to inspect hierarchies, nets, instances, and verify schematic integrity.
## Installation
1. **Install the package**:
```bash
pip install -r requirements.txt
```
2. **Start the SkillBridge Server in Virtuoso**:
In your Virtuoso CIW window:
```lisp
load("/path/to/your/python/site-packages/skillbridge/resources/server.il")
pyStartServer(?port 5000)
```
## Tools Available
* **`connect(host, port)`**: Connects to the Virtuoso session.
* **`get_instances(lib, cell)`**: Lists all instances (components) in the schematic.
* **`get_nets(lib, cell)`**: Lists all nets and their connections (pins and instance terminals).
* **`inspect_instance(lib, cell, instance_name)`**: Get properties and parameters of a specific component.
* **`check_and_save(lib, cell)`**: Runs `schCheck` and `dbSave` to validate the schematic.
## Configuration
