15 years agoproblem on insatntiated pll (EP2C5F256I8)
Hi,
i have used EP2C5F256I8 in my project,which requires 16 mhz clk to be converted into 32 mhz clk and i have generated a pll using megawizard.I would like to know whether - the output of the pll must be locked. - and i have seven modules that is to be driven by pll clk, can it be connected by signal from instantiated pll block. Kindly help me by providing some information. Thank You.1 Reply

When you assign the signal to an FPGA pin your can check it easy with a scope. You can connect all your modules to the pll output. Kind regards GPK
