## 🚀 Quick Start

### 1. Install SDK

```bash
npm install @wia/semiconductor-design
```

### 2. Create RTL Design

```typescript
import { RTLDesign, Module, Signal } from '@wia/semiconductor-design';

const design = new RTLDesign({
  name: 'my_chip',
  standard: 'WIA-SEMI-001',
  version: '1.0.0'
});

// Define module
const topModule = new Module({
  name: 'top',
  ports: {
    clk: new Signal({ direction: 'input', width: 1 }),
    rst_n: new Signal({ direction: 'input', width: 1 }),
    data_in: new Signal({ direction: 'input', width: 32 }),
    data_out: new Signal({ direction: 'output', width: 32 })
  }
});

design.addModule(topModule);
```

### 3. Run Verification

```typescript
import { Verification, TestBench } from '@wia/semiconductor-design';

const verification = new Verification({
  design: design,
  methodology: 'UVM',
  coverage: {
    functional: true,
    code: true,
    toggle: true,
    fsm: true
  }
});

const testbench = new TestBench({
  dut: topModule,
  clock_period: 10, // ns
  stimulus: 'directed_random'
});

const results = await verification.run(testbench);
console.log(`Coverage: ${results.coverage}%`);
console.log(`Tests passed: ${results.passed}/${results.total}`);
```

### 4. Synthesize Design

```typescript
import { Synthesis } from '@wia/semiconductor-design';

const synthesis = new Synthesis({
  design: design,
  technology: 'TSMC_5nm',
  constraints: {
    clock_frequency: 2000, // MHz
    power_budget: 1.5, // W
    area_constraint: 10 // mm²
  },
  optimization: 'balanced' // 'power' | 'performance' | 'area' | 'balanced'
});

const netlist = await synthesis.run();
console.log(`Area: ${netlist.area} mm²`);
console.log(`Power: ${netlist.power} W`);
console.log(`Frequency: ${netlist.max_frequency} MHz`);
```

  always @(posedge clk or negedge rst_n) begin
    if (!rst_n) begin
      sum      <= {WIDTH{1'b0}};
      overflow <= 1'b0;
