Creating OTN_cascade or SDI_cascade Instances at a Low or Medium IP Bandwith Causes the Arria® 10 and Cyclone® 10 GX fPLL or ATX PLL IP Parameter Editor GUI to Encounter an Error Related to f_max_pfd

Description

If you set the fPLL or ATX PLL IP bandwidth to low or medium for Arria® 10 and Cyclone® 10 GX devices while attempting to create OTN_cascade or SDI_cascade instances, the IP Parameter GUI might display an error that relates to f_max_pfd.

This issue affects the Quartus® Prime Standard Edition Software and the Quartus® Prime Pro Edition Software.

Resolution

In the fPLL or ATX PLL IP Parameter Editor, you cannot select the bandwidth after you select the OTN or SDI protocol. Therefore, before you create OTN_cascade or SDI_cascade instances, first select Basic from the Protocol mode pull-down menu and then select High from the Bandwith pull-down menu.
