|
||||
|
||||
## 3. 问题
|
||||
|
||||
### 3.1 发现的问题
|
||||
|
||||
1. Force存在±10mV抖动 <a id="custom-anchor1"></a>
|
||||
|
||||
2. 取得正确的测量结果的流程较为复杂，需： <a id="custom-anchor2"></a>
|
||||
1. 在取得初始值前通过ATE_Debugger发送指令：newdpsfunc("newdpsinitvalue","enable");
|
||||
2. 上位机连接获取初始值
|
||||
3. 检查初始值无误后上传初始值至Zynq中
|
||||
4. 通过ATE_Debugger发送指令：newdpsfunc("newdpsinitvalue","disable");
|
||||
5. 执行测量
|
||||
|
||||
3. 在ClampI模式下(FVMV/FVMI)，若Clamp值与Force值接近(如80mA档位Clamp60mA,Force70mA;2mA档位Clamp1mA,Force1.5mA)则Force输出与Sense管脚及对应信号链均会出现震荡，且在极端情况下震荡 ***可能不收敛*** <a id="custom-anchor3"></a>
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 3.2 原因分析
|
||||
|
||||
1. 初步推测由地平面噪声引入，整板均存在，影响Force输出稳定性
|
||||
2. ADC计算公式不同，现通过固件进行区分修正，导致需额外指令切换计算公式，猜测固件通过映射初始值进行转换
|
||||
3. 由于Clamp经过采样电阻后作为反馈输入运放构成Clamp电压，但其反馈、试探过程时间较长且可能导致不收敛，在这过程中输出电压不受控
|
||||
|
||||
## 4. 测试结论
|
||||
|
||||
Force存在噪声影响稳定性，Measure欲获得正确回读值需发送指令，过程较为复杂，Clamp除短路时生效外基本无实用意义

|
||||
## 四、实验步骤
|
||||
|
||||
### 1. 准备工作
|
||||
<!-- 分步骤描述准备过程 -->
|
||||
1) 步骤描述1：在K7板上断开通道4 TMUX输出，将通道2输出与通道4短接
|
||||
2) 步骤描述2：修改自校准程序，使其可以将`Strobe Edge`,`VOH`分别作为`Shmoo`横纵坐标，以方便和示波器波形做对应
|
||||
3) 步骤描述3：生成`Pattern`，通道2 Drive `0/1`， 通道4 Compare `H/L`
|
||||
|
||||
|
||||
### 2. 测试流程
|
||||
<!-- 按顺序记录关键操作 -->
|
||||
1) 步骤描述1：固定`VIH=3.5 V，VIL=0 V`，从`Period=30 ns`开始，以`Step=1`向高频运行`Shmoo`，执行`20`次，至`Period=10 ns`; `Shmoo`设定为 `VOH=2.0~5.0(V) Edge=2.4~4.4`
|
||||
2) 步骤描述2：新建测试项，仅运行`Pattern`，同时使用相同`VIH,VIL`手动调整`Period`，采集`Period=30,25,20,15,12 (ns)`的通道2输出波形
|
||||
3) 步骤描述3：将相同`Period`下，步骤2获得的`Shmoo`与步骤3获得的示波器进行对比，验证`Shmoo`正确性

|
||||
|
||||
## 七、结论与建议
|
||||
|
||||
✅ **实验结论**
|
||||
|
||||
1. `TPS54821` 不可使用当前切换反馈电阻的方式切换输出电压，根据现象可反推出存在瞬时大电流`
|
||||
2. 此瞬时大电流会拉低板卡上主要的供电：`+15V`
|
||||
1. 在`32DPS`的配置下，`+15V`会被拉低至`~13V`
|
||||
2. 在`64DPS`的配置下，`+15V`会被拉低至`~12V`
|
||||
3. K7的二级电源`+5V`的`EN`通过分压电阻分压`VIN`，由于配比问题，EN的VIN阈值约为`13V`,低于此值K7次级电源会掉电
|
||||
4. `TPS54821`在`64DPS`配置下，切换输出电压时，存在长时间处于`Overcurrent`的可能性，此时芯片将进入`~37ms(16384 cycles)`的关断状态，之后重启，此时输出电压将缓慢滑落，直到重启
|
||||
|
||||
⚠️ **改进建议**
|
||||
|
||||
- 建议1：修改`ARM固件`，避免64DPS**同时**切换运放供电
|
||||
- 建议2：修改`K7 BOM`，更换EN分压电阻，允许更多的VIN跌落
|
||||
- 建议3：修改`DPS裸板`，调整修改电源输出电压的方式

# RMA报告：嘉兆UT_20251226
|
||||
|
||||
## 基本信息
|
||||
|
||||
| 项目 | 内容 |
|
||||
|--------------|-----------------------|
|
||||
| 实验日期 | `2025-12-26` |
|
||||
| 负责人 | `沈浴阳` |
|
||||
| 工厂名称 | `嘉兆` |
|
||||
| 客户名称 | `PY` |
|
||||
| 待测芯片 | `PY32F410` |
|

| 测试类型 | `CP` |

|
||||
|
||||
---
|
||||
|
||||
## 一、问题背景
|
||||
|
||||
在客户芯片所需要的测试流程中存在对芯片管脚`PD7`进行`Trim,Write Data,Verify`的流程，
|
||||
|
||||
根据测试要求，需要在测试时将该管脚通过`Relay`连接/断开一`1uF电容`至`GND`
|
||||
|
||||
若测试时`Relay`未正确动作即该管脚未连接该对地电容而悬空时会导致回读电压值抖动并偏离容许范围导致测试失败
|
||||
|
||||
工厂现场发现存在部分板卡出现稳定Fail且检查数据后发现管脚电压不稳定，故怀疑测试时`Relay`未正确动作，故怀疑`Relay控制脚`所对应板卡`UT通道`存在问题

## 三、实验步骤
|
||||
|
||||
### 1. 准备工作
|
||||
|
||||
<!-- 分步骤描述准备过程 -->
|
||||
1) 步骤描述1：板卡连接面板及通道板
|
||||
2) 步骤描述2：确保`Socket`、芯片正确放置并连接至通道板
|
||||
3) 步骤描述3：将`UT`、`Relay`正确连接至通道板
|
||||
|
||||
### 2. 复现流程
|
||||
<!-- 按顺序记录关键操作 -->
|
||||
1) 步骤描述1：板卡上电
|
||||
2) 步骤描述2：启动软件，加载Stil，连接板卡
|
||||
3) 步骤描述3：Mark多余测试项
|
||||
4) 步骤描述4：执行测试，检查Log
|
||||
|
||||
|
||||
### 3. 调试记录
|
||||
|
||||
1) 单独执行1p024_Trimming, Trimming_Write, 1p024_Verify; 返回Pass，结果无异常
|
||||
2) 执行所有Trimming及Verify，查看结果，1p024_Verify Fail，其他测试项Pass
|
||||
3) 控制变量，发现1p024_Trimming与2p5_Trimming或2p9_Trimming测试项一同运行时会导致1p024_Verify Fail
|
||||
4) 将管脚直接短接电容作为对比，发现执行相同流程1p024_Verify可以Pass,确认与`Relay`存在与否有关
|
||||
5) 使用示波器观察波形，得到后续记录波形

```

||||
|
||||
---
|
||||
|
||||
## 六、结论与建议
|
||||
|
||||
✅ **实验结论**
|
||||
|
||||
1. 由于测试流程，会导致电容上残留有前序测试项所留电压
|
||||
2. 由于测试流程，Trimming最后为大电压测试，而Verify第一项为最小电压挡位测试，此时又由于使用`FZMV`的小电压档(5uA)且`Measure`等待时间较短，导致电容上电压在仍未稳定(多余电压未释放)时进行测量，导致测量值偏大，致使测试Fail
|
||||
|
||||
⚠️ **解决建议**
|
||||
|
||||
1. 在最后一项Trimming测试项中不断开`Relay`使外接电容自然放电
|
||||
2. 调整1p024_Verify测试项中`FZMV`挡位，使用`2mA`档以加快电荷释放，同时在允许范围内适当增加延时，确保Measure时电压稳定

# RMA报告：APT32 Trim问题分析
|
||||
|
||||
## 基本信息
|
||||
| 项目 | 内容 |
|
||||
|--------------|-----------------------|
|
||||
| 实验日期 | `2026-07-24` |
|
||||

| 板卡编号 | `` |
|

|

|
||||
## 一、问题背景
|
||||
|
||||
工厂反应PPMU2.0板卡对APT32F0313进行CP测试时，出现Vnege_Trim测试项Fail的情况，且该异常跟随板卡迁移
|
||||
具体表现为：
|
||||
- Trim Code写入后，发送Measure指令从Tp管脚量得得电压与期望值不符，导致Code中二分法得出错误结果进而使得测试项出现Fail
|
||||
- 进一步细究后发现，通过执行一次Trim Code写入，写入固定Code后重复发送Measure指令并进行测量，可得到异常结果，并与前述异常结果相符，故可以得出该问题实际出现在Measure指令到Tp管脚测量中

## 三、实验环境
|
||||
- **硬件配置**
|
||||
- 工厂寄回PPMU2.0板卡两套
|
||||
- IP分别为14与17
|
||||
- 其中 ***14*** 板卡为正常板卡，***17***板卡为异常板卡
|
||||
- 工程机(PC)
|
||||
- **软件环境**
|
||||
SOC软件: v1.4.0-1070
|
||||
|
||||

||||
|
||||
## 四、实验步骤
|
||||
### 1. 准备工作
|
||||
<!-- 分步骤描述准备过程 -->
|
||||
1) 本次实验受限于实验室机台，使用1K+PIB形式进行验证
|
||||
2) 收到从工厂发来的 ***盲binding*** FT颗粒若干 (*需注意现场为CP测试*)，购买QFN32 Socket并通过飞线至PIB的形式连接至板卡通道
|
||||
3) 使用与工厂相同的软固件版本以保持一致
|
||||
4) 从辛明翰处获得现场使用工程文件
|
||||
|
||||
### 2. 复现流程
|
||||
<!-- 按顺序记录关键操作 -->
|
||||
1. 直接运行工厂项目文件，发现
