output reg [7:0] count
);
always @(posedge clk or posedge rst) begin
if (rst)
count <= 8'b0;

## Configuration
### Docker Desktop MCP Integration
This method uses Docker Desktop's built-in MCP extension for the easiest setup experience.
#### Prerequisites
- Docker Desktop 4.39.0+ installed and running
- Claude Desktop installed
#### Setup Steps
1. **Install Docker Desktop Extension:**
- Launch Docker Desktop
- Go to "Extensions" from the left menu
- Search for "AI Tools" or "Docker MCP Toolkit"
- Install "Labs: AI Tools for Devs" extension
2. **Configure Docker MCP Connection:**
- Open the installed "Labs: AI Tools for Devs" extension
- Click the gear icon in the upper right corner
- Select the "MCP Clients" tab
- Click "Connect" for "Claude Desktop" or "Cursor IDE"

This automatically configures Claude Desktop and Cursor IDE with:
```json
{
"mcpServers": {
"MCP_DOCKER": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"alpine/socat",
"STDIO",
"TCP:host.docker.internal:8811"
]
}
}
}
```
### Cursor IDE Setup
1. **Add Your EDA MCP Server:**
- Locate your Claude Desktop config file, Settings > Developer > Edit Config:
- **macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows:** `%APPDATA%\Claude\claude_desktop_config.json`
- Add your EDA server to the existing configuration:
```json
{
"mcpServers": {
"MCP_DOCKER": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"alpine/socat",
"STDIO",
"TCP:host.docker.internal:8811"
]
},
"eda-mcp": {
"command": "node",
"args": [
"/absolute/path/to/your/eda-mcp-server/build/index.js"
],
"env": {
"PATH": "/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin",
"HOME": "/your/home/directory"
}
}
}
}
```
2. **Restart Claude Desktop** and verify both servers are running in Settings > Developer.
### Cursor IDE Setup
1. **Open Cursor Settings:**
- Press `Ctrl + Shift + P` (Windows/Linux) or `Cmd + Shift + P` (macOS)
- Search for "Cursor Settings"
- Navigate to "MCP" in the sidebar
2. **Add MCP Server:**
Click "Add new MCP server" and configure:
```json
{
"mcpServers": {
"MCP_DOCKER": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"alpine/socat",
"STDIO",
"TCP:host.docker.internal:8811"
]
},
"eda-mcp": {
"command": "node",
"args": [
"/absolute/path/to/your/eda-mcp-server/build/index.js"
],
"env": {
"PATH": "/usr/local/bin:/opt/homebrew/bin:/usr/bin:/bin",
"HOME": "/your/home/directory"
}
}
}
}
```
3. **Enable MCP Tools:**
- Go to Cursor Settings → MCP
- Enable the "eda-mcp" server
- You should see the server status change to "Connected"
## Usage Examples
### 1. Verilog Synthesis
```
Ask Claude: "Can you synthesize this counter module for an ice40 FPGA?"
module counter(
input clk,
input rst,
output [7:0] count
);
reg [7:0] count_reg;
assign count = count_reg;
always @(posedge clk or posedge rst) begin
if (rst)
count_reg <= 8'b0;
else
count_reg <= count_reg + 1;
end
endmodule
```
### 2. Verilog Simulation
```
Ask Claude: "Please simulate this adder with a testbench"
// Design
module adder(
input [3:0] a,
input [3:0] b,
output [4:0] sum
);
assign sum = a + b;
endmodule
// Testbench will be generated automatically or you can provide one
```
### 3. ASIC Design Flow
```
Ask Claude: "Run the complete ASIC flow for this design with a 10ns clock period"
module simple_cpu(
input clk,
input rst,
input [7:0] data_in,
output [7:0] data_out
);
// Your RTL design here
endmodule
```
**What you get after completion:**
- `runs/RUN_*/final/gds/design.gds` - Final GDSII layout
- `runs/RUN_*/openlane.log` - Complete execution log
- `runs/RUN_*/reports/` - Timing, area, power analysis reports
- All intermediate results (DEF files, netlists, etc.)
### 4. Waveform Analysis
```
Ask Claude: "View the waveforms from the simulation with project ID: abc123"
```
## Troubleshooting
### Common Issues
1. **MCP Server Not Detected:**
- Verify the absolute path in configuration
- Check that Node.js is installed and accessible
- Restart Claude Desktop/Cursor after configuration changes
2. **Docker Permission Errors:**
```bash
sudo groupadd docker
sudo usermod -aG docker $USER
sudo reboot
```
3. **Tool Not Found Errors:**
- Verify tools are installed: `yosys --version`, `iverilog -V`, `gtkwave --version`
- Check PATH environment variable in MCP configuration
- On macOS, ensure Homebrew paths are included: `/opt/homebrew/bin`
4. **OpenLane Timeout:**
- The server has a 10-minute timeout for OpenLane flows
- For complex designs, consider simplifying or running multiple iterations
5. **GTKWave/KLayout GUI Issues:**
- On macOS: GTKWave/KLayout may need manual approval in Security & Privacy settings
- On Linux: Ensure X11 forwarding is working if using remote systems
- On Windows: Ensure GUI applications can launch from command line
### Debugging
1. **Check MCP Server Logs:**
- **Claude Desktop:** `~/Library/Logs/Claude/mcp*.log` (macOS)
- **Cursor:** Check the MCP settings panel for error messages
2. **Test Tools Manually:**
```bash
yosys -help
iverilog -help
docker run hello-world
gtkwave --version
klayout -v
```
3. **Verify Node.js Environment:**
```bash
node --version
npm --version
```
