Hello there,

I have a similar problem pertaining two FPGAs together. Currently, my design has exceeded my FPGA's LE count and therefore, i am planning to connect two altera UP2 boards using JTAG. The UP board has a CPLD (EPM7128) and FPGA (Flex 10k).

from my understanding, if Quartus detected the assembly is larger than the device, it will generate more than one programming file..such as pof_1. However, the web edition software could notgenerate more than one program file. Instead, i have this error:

***

Error: Project requires 6182 logic cells, but the selected device can contain only 3744 logic cells

Error: Can't find fit

Error: Quartus II Fitter was unsuccessful. 2 errors, 1 warning

Info: Allocated 180 megabytes of memory during processing

***

Could it be my web edition quartus's limitation?
