Generate pll settings in batch mode

Dear all,

For a highly reconfigurable pll i need to build a table with pll settings. For each scenario defined by the combination of input frequency and output frequency one needs to know the counter settings (m,n,c) and loopfilter/chargepump settings (i,c,r). The counter settings are relatively easy to calculate but i cannot find any information on the other settings (i,c,r).

The only procedure to establish this table i found would be going trough the megawizard for each scenario and write down the "magicly" chosen pll settings by quartus. A VERY boring, time consuming task :mad: !

Is there any way to script this procedure? Or is their another wayto obtain these tables?

Regards,

Johannes
