FPGA时序分析中的工艺角：从PVT原理到建立保持时间验证在数字电路设计中，静态时序分析（STA）是确保芯片功能正确和性能达标的核心验证手段。其基本原理是通过计算信号在逻辑路径上的传播延迟，检查建立时间和保持时间是否满足寄存器采样要求。这项技术的核心价值在于，它能在芯片制造前就预测并消除时序违规，极大提高设计成功率。然而，实际芯片性能会受到工艺波动、电压变化和温度漂移（合称PVT）的显著影响。为了覆盖这些不确定性，时序分析必须采用基于工艺角的边界模型——用最慢的工艺角模型验证建立时间，用最快的工艺角模型验证保持时间。这种分析方法广泛应用于FPGA和ASIC设计流程阅读详情

我从asp.net webservice获取arrylist数据
在后台代码中得到数据并绑定到listview，但是显示出来的是一串字符串，不知道为什么，大神们帮忙看看。谢谢

public class voteporformance extends Activity 主要代码:



if (envelope.getResponse()!= null){

			          SoapObject result=(SoapObject) envelope.bodyIn;

			          SoapObject detail=(SoapObject) result.getProperty(methodName+"Result");

			          

			          list= new ArrayList<rating>();

			          for (int i = 0; i < detail.getPropertyCount(); i++) {

			        	  SoapObject mstr=(SoapObject)detail.getProperty(i);

			        	  rating a = new rating();

			        	 

			        	  

			        	  String plusreason = mstr.getProperty("Plusreason").toString();

			        	  String average = mstr.getProperty("Average").toString();

			        	  String plusdepart = mstr.getProperty("Plusdepart").toString();

			        	  String lessdepart = mstr.getProperty("Lessdepart").toString();

			        	  String lessreason =  mstr.getProperty("Lessreason").toString();

			        	  String branchName = mstr.getProperty("Branchname").toString();

			        	  String ratingmonth = mstr.getProperty("Datetime").toString();

			        	  

			        	  a.setPlusreason(plusreason);

			        	  a.setAverage(average);

			        	  a.setPlusdepart(plusdepart);

			        	  a.setLessdepart(lessdepart);

			        	  a.setLessreason(lessreason);

			        	  a.setBranchName(branchName);

			        	  a.setRatingmonth(ratingmonth);

			        	  list.add(a);

					}

			          Toast.makeText(voteporformance.this,

								getString(R.string.Average),

								Toast.LENGTH_SHORT).show();

			      	ArrayAdapter<rating> adapter = new ArrayAdapter<rating>(this,R.layout.list_items,list);			          

mylListView.setAdapter(adapter);
