Pack:2310 - Too many comps of type "DSP48A1" found to fit this device.

Hello everybody,

I have a problem in routhing. (the target device is a spartan 6 -> 6slx150fgg484-2)

The error is :

Pack:2310 - Too many comps of type "DSP48A1" found to fit this device. New map ERROR Map:237 - The design is too large to fit the device. Please check the Design Summary section to see

My model occupies only 75% of the number of slices registers but my model need 357 DSPA and the spartan6 have only 180 DSPA.

How can i do ? Why the synthesis tool not uses others slice registers to do DSP ?

Thank you

you use already 75% of your slice register which is alot . and you hadly have enought DSP block. i say you need to go for bigger fpga , or change you design.
