18 years agoProblem with ALTPLL_RECONFIG in Cyclone III
Device: Cyclone III (EP3C16Q240C8)
I created ALTPLL_RECONFIG with ports to write to the scan chain from external ROM during run time, created ALTPLL with optional inputs for dynamic reconfiguration, generated configuration file (MIF). I done module assembly and begun simulation. All step's I done like write in ug_altpll_reconfig.pdf ("Implementing Multiple-MIF PLL Reconfiguration Using an External ROM") After simulation I have this message: "PLL Reprograming cpmpleted with the following values..." I take generated MIF file in ALTPLL for my parameters and creat write for rom in wafeform and creat reconfig signal i wafefrom. But after scanchain gone I have no frequencies and lock in low!!!! On site have no Annex and examples on reconfiguartion Cyclone III in comparison with another devices! :( Why is not work? :confused:
