# 读取电路图和设计规则 circuit = read_circuit('circuit.xml') rules = read_rules('rules.xml')

好的，以下是可能需要补充的代码：

from lxml import etree

def read_circuit(file_path):
    # 解析电路图 XML 文件
    xml_data = etree.parse(file_path)
    root = xml_data.getroot()

    # 获取电路图的基本信息，例如电路图名称、设计工具版本等
    circuit_info = {}
    for child in root.iter():
        if child.tag in ['design_tool', 'design_tool_version', 'circuit_name']:
            circuit_info[child.tag] = child.text

    # 获取电路图中的器件列表
    devices = []
    for device_xml in root.iterfind('devices/device'):
        device = {}
        device['name'] = device_xml.get('name')
        device['type'] = device_xml.get('type')
        device['pins'] = {}

        # 获取器件的引脚列表
        for pin_xml in device_xml.iterfind('pins/pin'):
            pin = {}
            pin['name'] = pin_xml.get('name')
            pin['direction'] = pin_xml.get('direction')
            pin['net'] = pin_xml.get('net')
            device['pins'][pin['name']] = pin

        devices.append(device)

    return {'info': circuit_info, 'devices': devices}

def read_rules(file_path):
    # 解析设计规则 XML 文件
    xml_data = etree.parse(file_path)
    root = xml_data.getroot()

    # 获取设计规则中的所有规则
    rules = []
    for rule_xml in root.iterfind('rule'):
        rule = {}

        # 获取规则名称、描述和优先级等信息
        rule['name'] = rule_xml.get('name')
        rule['description'] = rule_xml.get('description')
        rule['priority'] = int(rule_xml.get('priority', 0))

        # 获取规则的参数信息
        rule['params'] = {}
        for param_xml in rule_xml.iterfind('params/param'):
            rule['params'][param_xml.get('name')] = param_xml.get('value')

        # 获取规则中的所有条件
        rule['conditions'] = []
        for condition_xml in rule_xml.iterfind('conditions/condition'):
            condition = {}
            condition['device'] = condition_xml.get('device')
            condition['pin'] = condition_xml.get('pin')
            condition['net'] = condition_xml.get('net')
            condition['value'] = condition_xml.get('value')
            rule['conditions'].append(condition)

        rules.append(rule)

    return rules

以上代码中，`read_circuit` 函数用于解析电路图的 XML 文件，返回一个包含电路图信息的字典对象；`read_rules` 函数用于解析设计规则的 XML 文件，返回一个包含所有规则信息的列表对象。您可以根据需要进行调整和修改。
