Hi Mark,
Thanks for the help.
I copy the utility summary from MATLAB as follows -
Device Utilization Summary:
Number of BUFGs 3 out of 32 9%
Number of DCM_ADVs 1 out of 12 8%
Number of DSP48Es 64 out of 64 100%
Number of ILOGICs 65 out of 800 8%
Number of External IOBs 97 out of 640 15%
Number of LOCed IOBs 97 out of 97 100%
Number of External IOBMs 1 out of 320 1%
Number of LOCed IOBMs 1 out of 1 100%
Number of External IOBSs 1 out of 320 1%
Number of LOCed IOBSs 1 out of 1 100%
Number of OLOGICs 5 out of 800 1%
Number of RAMB18X2s 50 out of 148 33%
Number of RAMB36_EXPs 14 out of 148 9%
Number of Slice Registers 21382 out of 69120 30%
Number used as Flip Flops 21382
Number used as Latches 0
Number used as LatchThrus 0
Number of Slice LUTS 21127 out of 69120 30%
Number of Slice LUT-Flip Flop pairs 27717 out of 69120 40%
------------------------------------------------------------------
The model does use up all the DSP48Es (and some other devices).
But they are at most 100%. So it's ok in terms of resources?

Chao-Te
