mkdir -p ~/openlane-projects/my-design
cd ~/openlane-projects/my-design
# Create Verilog file (counter example)
cat > counter.v << 'EOF'
module counter (
input wire clk,
input wire rst,
output reg [7:0] count
);
always @(posedge clk or posedge rst) begin
if (rst)
count <= 8'b0;
else
count <= count + 1;
end

EOF
# Create configuration file
cat > config.json << 'EOF'
{
"DESIGN_NAME": "counter",
"VERILOG_FILES": ["counter.v"],
"CLOCK_PORT": "clk",
"CLOCK_PERIOD": 10.0

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
- 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
- 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:
{
"mcpServers": {
"MCP_DOCKER": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"alpine/socat",
"STDIO",
"TCP:host.docker.internal:8811"
]
}
}
}
Cursor IDE Setup
- 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:
{
"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"
}
}
}
}
- Restart Claude Desktop and verify both servers are running in Settings > Developer.
Cursor IDE Setup
- Open Cursor Settings:
- Press
Ctrl + Shift + P (Windows/Linux) or Cmd + Shift + P (macOS) - Search for "Cursor Settings"
- Navigate to "MCP" in the sidebar
- Add MCP Server:
Click "Add new MCP server" and configure:
{
"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"
}
}
}
}
- 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 layoutruns/RUN_*/openlane.log - Complete execution log runs/RUN_*/reports/ - Timing, area, power analysis reports- All intermediate results (DEF files, netlists, etc.)
Ask Claude: "View the waveforms from the simulation with project ID: abc123"
Troubleshooting
Common Issues
- 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
- Docker Permission Errors:
sudo groupadd docker
sudo usermod -aG docker $USER
sudo reboot
- 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
- OpenLane Timeout:
- The server has a 10-minute timeout for OpenLane flows
- For complex designs, consider simplifying or running multiple iterations
- 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
- Check MCP Server Logs:
- Claude Desktop:
~/Library/Logs/Claude/mcp*.log (macOS) - Cursor: Check the MCP settings panel for error messages
- Test Tools Manually:
yosys -help
iverilog -help
docker run hello-world
gtkwave --version
klayout -v
- Verify Node.js Environment:
node --version
npm --version
Support
For issues and questions:
- Check the troubleshooting section above
- Review MCP server logs
- Test individual tools manually
- Open an issue with detailed error messages and environment information
Note: This MCP server requires local installation of EDA tools. The server acts as a bridge between AI assistants and your local EDA toolchain, enabling sophisticated hardware design workflows through natural language interaction.
