10 years agoFractional PLL reconfiguration
I am using Arria V FPGA for the current project. Its required for me to switch between different frequencies at run time.
I downloaded the reference design mentioned in link of AN-661 "Implementing Fractional PLL Reconfiguration with Altera PLL and Altera PLL Reconfig IP Cores", Design Example -1. However when I try to restore the archived file, I get the following 2 errors: Error (125048): Error reading Quartus II Settings File D:/kiran/pll_reconfig_mnc_fifteen/Test.qsf, line 249 Error (23031): Evaluation of Tcl script e:/altera/12.0/quartus/common/tcl/apps/qpm/qar.tcl unsuccessful What might be the problem.
