摘要 这篇论文提出了一种基于扩展卡尔曼滤波(EKF)的实时视觉辅助惯性导航算法。这项工作的主要贡献是推导出一个测量模型，该模型能够表达从多个相机姿态观察静态特征时产生的几何约束。该测量模型不需要将三维特征位置包含在状态向量EKF中，并且线性化误差范围里是最优的。我们提出的视觉辅助惯性导航算法，其计算复杂度仅为特征量的线性，能够在大规模的真实环境中进行高精度的姿态估计。大量的实验结果证明了该算法的性...

1.DRC检查出现short-Circuit Constraint，数量6个； 2.此时回到PCB界面 回到PCB界面，双击错误栏中信息，一般直接跳到错误元器件处。但是实际发现是一片灰色。 而且错误处坐标（-1168，-1284）附近； 但是PCB现实左下角最低坐标为（-311，-280）； 3.进一步拖动，发现拖拽不到异常处的坐标位置 PCB相对背景的坐标位置竟然是固定的，怎么拖拽都没法逃脱一定范围。 4.切换到三维视图 当切换到三维视图，终于看到了异常位置处的情况。因为和PCB距离较远，所以显示很微

最近用Protell99画了一个传感器小面板，因为比较简单就直接在PCB中画了，也没有通过原理图导入。在画完PCB后进行DRC检查的时候总是报Short Circuit Constraint错误，仔细检查PCB感觉也没有那个地方短路。我做了一个最简单的实验，仅仅将导线连接到一个焊盘上再做DRC检查同样会报 Short Circuit Constraint错误。通过在网上查询总算找到了错误的原因，...

AD10中不会报这个错误； 将元器件的封装引脚的jumper id设置为0即可； jumper id使能时必须大于0，jumper id相同的引脚意味着他们只能有相同的net连接。 参考1 参考2

Short-Circuit Constraint: Between Pad J3 on top
最新发布
06-18
### Short-Circuit Constraint Solution for Pad J3 in Circuit Design In circuit design, a short-circuit constraint refers to the prevention of unintended electrical connections that could lead to malfunction or damage. For Pad J3, ensuring no short circuits occur involves both design and verification processes. Here are some approaches to address short-circuit constraints: 1. **Design Rule Checking (DRC)**: Utilize DRC tools during the layout phase to automatically detect any potential short circuits. These tools can verify spacing between metal layers, vias, and pads against predefined rules[^3]. Ensuring that Pad J3 adheres strictly to these rules is crucial. 2. **Electrical Rule Checking (ERC)**: ERC complements DRC by analyzing the electrical aspects of the design. It checks for improper connections, such as multiple outputs driving the same net without proper buffering, which could cause a short circuit on Pad J3[^4]. 3. **Netlist Analysis**: Perform a thorough analysis of the netlist to ensure that Pad J3 is not inadvertently connected to another pad or internal node through an unintended path. This step often involves manual inspection alongside automated tools to identify complex interconnections[^5]. 4. **Power and Ground Connections**: Verify that power and ground connections around Pad J3 are correctly implemented. Improper routing of power or ground lines can lead to short circuits if they accidentally connect to signal lines associated with Pad J3[^6]. 5. **Simulation and Verification**: Use simulation tools to model different scenarios where Pad J3 might encounter a short circuit. This includes transient analysis to observe how the circuit behaves under fault conditions, helping to identify weak points in the design[^7]. ```python # Example Python script for simulating short-circuit conditions def simulate_short_circuit(voltage, resistance): current = voltage / resistance # Ohm's Law return current voltage = 5 # Volts resistance = 0.1 # Ohms (low resistance to simulate short) current = simulate_short_circuit(voltage, resistance) print(f"Simulated short-circuit current: {current} A") ```
