Q II环境下出现了如下警告,请教高人给予指点解决办法: ----------------------------------------------------------------------  1. Warning:  Found 6 output pins without output pin load capacitance assignment          说是缺少容性负载,怎么样设置容性负载值才是合理的?   2. Critical Warning: Timing requirements were not met. 不满足时序要求,这个问题好像比较严重。在TimeQuest下,将TsuTh等设置为多少事合理的?   3. Warning: Skipped module PowerPlay Power Analyzer due to the assignment FLOW_ENABLE_POWER_ANALYZER   由于分配FLOW_ENABLE_POWER_ANALYZER,跳过模块“PowerPlay功耗分析仪”。 如何解决?   4. Warning: Parallel compilation is not licensed and has been disabled   5. Warning: Feature LogicLock is only available with a valid subscription license. You can purchase a software subscription to gain full access to this feature. 是由于软件是免费版本的原因么?如果是,影响逻辑综合结果么?如果影响,如何改进之?   6. Critical Warning: Synopsys Design Constraints File file not found: 'mapan_model.sdc'. A Synopsys Design Constraints File is required by the TimeQuest Timing Analyzer to get proper timing constraints. Without it, the Compiler will not properly optimize the design. 这也是一个严重警告。如何生成.sdc文件?.sdc文件中的TsuTh等设置为多少事合理的?   此帖出自小平头技术问答

6. Critical Warning: Synopsys Design Constraints File file not found: 'mapan_model.sdc'. A Synopsys Design Constraints File is required by the TimeQuest Timing Analyzer to get proper timing constraints. Without it, the Compiler will not properly optimize the design.

这也是一个严重警告。如何生成.sdc文件?.sdc文件中的TsuTh等设置为多少事合理的?

 

 

 

 

 

你好,你的.sdc文件怎么建立的啊,我也遇到了这个问题,帮忙解决下啊,感谢啊
