Why can't the IOPLL bandwidth register be read using PLL Reconfig Intel® FPGA IP? - Why can't the IOPLL bandwidth register be read using PLL Reconfig Intel® FPGA IP? Description You may encounter a problem performing a read transaction of the bandwidth register using the PLL Reconfig Intel® FPGA IP core in Intel® Arria® 10 devices. This affects reading the Loop Filter Setting and Charge Pump Setting of the IOPLL. No known issues are performing read transactions on other registers. There are no known issues performing write transactions on any registers, so there are no limitations in performing PLL reconfiguration using the IP. Resolution There is no workaround. Avoid performing read transactions on the bandwidth register.
