本文介绍了一个关于EDA工具中预综合信号无法正确添加到SignalTap II ELA的问题及其解决方案。通过关闭Altera Quartus II中的增量编译选项，可以在设计细化后但未进行综合优化前，成功添加预综合信号。

以前遇到过几次类似问题，只知道关闭一下就可以通过，但是没搞清原理。在Altera的一篇文档里找到了答案:

In the Settings dialog box, under the Compilation Process Settings section, select Incremental Compilation. Set the Incremental Compilation option to Off.
By turning off the Incremental Compilation option, pre-synthesis signals can be added to the SignalTap II ELA in the later sections. Pre-synthesis signals exist after design elaboration, but before any synthesis optimizations are done. This set of signals should reflect your register transfer level (RTL) signals.

就是要关闭"Incremental Compilation"增量编译.

谢谢riple!!!
