UCD90SEQ48EVM-560: Fusion Digital Power Designer无法找到UCD9090

Part Number: UCD90SEQ48EVM-560
Other Parts Discussed in Thread: UCD9090, , UCD9090A

Fusion Digital Power Designer无法找到UCD9090,使用的是UCD90SEQ48EVM-560开发板,并弹窗如下

相似的也尝试过使用UCD9090A或者新的UCD9090芯片,也尝试过参照这个开发板原理图自己画的小板子,都无法读到芯片。

之前曾经用这块开发板成功认到芯片了,后来有一段时间没有用了就读不了了,不知道是硬件有问题还是Fusion Digital Power Designer设置问题?

另外图示信号SMBALERT# ACK:Low不知道是否正常?请教有用过的告知,谢谢
