# AaLLM: End-to-End Analog Circuit Design Framework

## Overview
AaLLM is an open-source end-to-end multi-agent LLM workflow that automates analog circuit design from user specifications to complete netlist output, encompassing both topology generation and circuit sizing. This framework addresses the time-consuming, iterative nature of analog circuit design in nonlinear, high-dimensional design spaces.

## Core Methodology

### Key Components
1. **Automated Knowledge Base Creation**: Automatically extracts relevant technical knowledge from research papers and textbooks to combat manual data collection inefficiencies
2. **RAG-based Expert Emulation**: Implements Retrieval-Augmented Generation to emulate circuit design expertise using the automated knowledge base
3. **Tri-Agent Feedback System**:
   - **Designer Agent**: Determines circuit component values
   - **Critic Agent**: Scrutinizes the Designer's proposed values
   - **Evaluator Agent**: Arbitrates between Designer and Critic to minimize sizing iterations

### Technical Innovations
- **End-to-End Integration**: Combines topology generation and circuit sizing in a single workflow (unlike fragmented conventional approaches)
- **Novel Topology Generation**: Capable of creating innovative circuit topologies beyond conventional designs
- **Efficiency Gains**: Achieves 3x-4.5x reduction in SPICE calls and 40x decrease in wall-clock time compared to existing approaches
- **Performance**: Generated novel topologies achieve comparable or up to 3x higher Figure of Merit (FoM) than known topologies

## Use Cases
- Automated analog circuit design from natural language specifications
- Rapid prototyping of novel circuit topologies
- Educational tool for circuit design exploration
- Integration into EDA (Electronic Design Automation) workflows

## Implementation Guidelines
1. **Input**: User specifications in natural language format
2. **Knowledge Base**: Automatically constructed from domain literature
3. **Multi-Agent Workflow**: Designer → Critic → Evaluator feedback loop
4. **Output**: Complete netlist with optimized component values

## Performance Metrics
- **Figure of Merit (FoM)**: Comparable to or up to 3x higher than conventional topologies
- **SPICE Calls**: 3x-4.5x reduction at inference time
- **Wall-clock Time**: 40x decrease compared to existing multi-agent LLM pipelines
