ADS 2011 DesignGuide PLL Problem

請問，當我去執行DesignGuide PLL時會彈出錯誤的對話框(內容如下):
(vapi_runtime.ael line 6709, column 19)
Error opening library "ADS_sim_lib", cell "SYN_PF_FQ_A2P", view "schematic"
Open of ADS_sim_lib/SYN_PF_FQ_A2P/schematic failed - cellView for the design was not found
這表示我要去下載Library嗎，還是我破解不完全呢?
拜託，請各位前輩幫幫我。

LZ解决这个问题了没?遇到了同样的问题。
