[fpu] FPU compilation problem

[dmackesy@site.uottawa.ca]

Hi there,

I was hoping that someone might be able to give me a quick hand with a 
compilation error that I'm getting when trying to synthesize the FPU 
core in Quartus II 2.2.  The problem is in regards to line 315 of 
Post_Norm.v:

assign exp_f2i_1 = {{8{fract_in[47]}}, fract_in }<<f2i_shft;

The synthesis seems to be failing because the f2i_shft shift distance 
may be up to 256 bits, while exp_f2i_1 is only 56 bits wide.

Is there a known work-around for this problem?

Thanks very much.
Devin
