帮网友提问：

一是：在Analyze Post-Place & Route Static Timing process步骤，运行Analyze － Against Timing Constraints....后出现如下消息：

4 >AnalyzeTimingConstraints
EXCEPTION:StaticFileParsers:Xml_Parser.c:744:1.34 - Xml_ParseException Description: line 0:An exception occurred! Type:RuntimeException, Message:The primary document entity could not be opened. Id=C:/DOCUME~1/admini/LOCALS~1/Temp/xil_2040_5.twx

ERROR:Timing:2581 - Xml Parser Exception code 0 line 0:An exception occurred! Type:RuntimeException, Message:The primary document entity could not be opened. Id=C:/DOCUME~1/admini/LOCALS~1/Temp/xil_2040_5.twx
parsing file C:/DOCUME~1/admini/LOCALS~1/Temp/xil_2040_5.twx

请问这是什么意思，要如何解决？

二是在qst中写道：

1. Double-click the View/Edit Routed Design (FPGA Editor) process found in the Place
& Route group of processes. Your implemented design opens in the FPGA Editor.

但是我的ise中就没有View/Edit Routed Design (FPGA Editor)这个过程，这是怎么回事？和我安装的时modelsim有没有关系？

谢谢
