芯片测试工具系统Demo示例

一个简单的芯片测试工具系统Demo示例，包含基础功能和模拟测试流程，使用Python实现：

```python
import time
import random
import csv
from datetime import datetime

class VirtualChip:
"""模拟虚拟芯片设备"""
def __init__(self, chip_id):
self.chip_id = chip_id
self.connected = False
self.voltage = 3.3
self.temperature = 25.0

def connect(self):
"""模拟连接设备"""
time.sleep(1) # 模拟连接延时
self.connected = True
return random.choice([True, True, False]) # 10%概率连接失败

def read_voltage(self):
"""读取电压"""
if self.connected:
return self.voltage + random.uniform(-0.1, 0.1)
return None

def read_temperature(self):
"""读取温度"""
if self.connected:
return self.temperature + random.uniform(-2, 2)
return None

class TestManager:
"""测试管理系统"""
def __init__(self):
self.test_cases = [
{
'name': 'Voltage Test',
'desc': '测试供电电压',
'func': self._test_voltage,
'min': 3.0,
'max': 3.6
},
{
'name': 'Temperature Test',
'desc': '测试工作温度',
'func': self._test_temperature,
'min': 0,
'max': 40
}
]
self.log = []

def _test_voltage(self, chip):
value = chip.read_voltage()
return value, self.test_cases[0]['min'] <= value <= self.test_cases[0]['max']

def _test_temperature(self, chip):
value = chip.read_temperature()
return value, self.test_cases[1]['min'] <= value <= self.test_cases[1]['max']

def run_test_suite(self, chip):
"""执行完整测试流程"""
results = []
if not chip.connected:
results.append(('Connection', 'Device not connected', False))
return results

for case in self.test_cases:
value, passed = case['func'](chip)
result_str = f"{value:.2f} ({case['min']}-{case['max']})"
results.append((case['name'], result_str, passed))
self.log.append({
'timestamp': datetime.now(),
'test_case': case['name'],
'result': 'PASS' if passed else 'FAIL',
'value': value
})

return results

def generate_report(self, filename='test_report.csv'):
"""生成测试报告"""
with open(filename, 'w', newline='') as f:
writer = csv.writer(f)
writer.writerow(['Timestamp', 'Test Case', 'Result', 'Value'])
for entry in self.log:
writer.writerow([
entry['timestamp'].strftime('%Y-%m-%d %H:%M:%S'),
entry['test_case'],
entry['result'],
f"{entry['value']:.2f}"
])
```
