将设备从CY8C3666 LTI-030ES2切换到CY8C38 66 LTI 030时出现警告

当我将设备从CY8C3666 Lti-030ES2切换到CY8C38 66 LTI 030时,创建者会产生一个新的警告:
这意味着什么以及如何修复?谢谢
警告:STA.M90019:937 BXPCyTimeN.HTML:警告-1367:在从时钟(CyBuxCLK)到时钟(SPIXSCLK(0)γ同步/out)的路径中发现时间违反。(文件=C:PrimeC937 b937 ByPraseReCurrt\937 ByPC937 BPC.CysnCoDeExtEngp937 bxPCyTime.html)

我们和新的创造者有相似的问题,似乎有更多的检查。这是一件好事,但是,如果柏树提供更多的信息会更好。或者使用APP注释来解释这些警告是什么以及如何修复它。我认为目前最快的办法是发布一个支持案例,并使用CyPress支持来修复它。

  We have similar problem witht the new creator which seems to have more checking. That is a good thing, however, it would be better if Cypress supply more information. or have app notes to explain what those warnings are and how to fix it. I think the quickest way for now is to issue a support case and have Cypress support to fix it.

保持时间违反STA(静态时序分析)警告。你可以学习更多关于如何理解STA警告和如何调试,推出的PSoC Creator的帮助主题和静态时序分析的搜索。

  The hold time violation is STA warning(Static timing analysis). You can learn more about how to understand the STA warnings and how to debug them, launch the PSoC Creator Help Topics and search for Static Timing Analysis.

我得到了一个FAE的回应:
似乎创建者进入了一个无法绕行的数字路由环路。答案是删除SPI组件,并将另一个副本拖回示意图中。

  I got a response from a FAE:
    it seems that creator got in a digital routing loop that it couldn't get out. the answer is to delete the SPI component, and drag another copy back into the schematic.......
