PLL Reconfiguration .mif File Generation - Cyclone 4 GX

Hi,

I am working on PLL Dynamic Reconfiguration with GX Transceivers on Cyclone 4 device.

The .mif File generated to reconfigure the PLL is not 144x1 bit, but 48x16 bit since i use a duplex ALTGX configuration.

But the rom_data_in port in ALTPLL_Reconfig megafunction can be configured only for 1-bit .mif file.

So, how to generate a .mif file of size 144x1 bit for PLL reconfiguration with ALTGX megafunction?

Thanks,

Swami.

    Hi,

    To change the memory size you can use the tool from Quartus (open the memory and use edit->memory size wizard).
