How to use XtremeDSP DSP48A slice in Core Generator for Spartan-3A DSP?

Jump to solution

Hi All,

 

Why I can't use XtremeDSP Slice such as Multiply Accumulator in Core Generator (Version: 10.1.01) for Spartan-3A DSP FPGAs?

 

Can anyone help me, thanks.

 

Best Regards, 

Bingo Zhang

Hi RJ,

 

First, I think the installation should be correct.

 

And the problem is the dedicated IP Core which I need is gray (not available) in the Core Generator.

 

I have installed the latest IP update for ISE 10.1.

 

Could you please affirm this case again, thanks.

 

Best Regards,

Bingo Zhang

Are you talking about using the Multiply Accumulator v4.0 core in coregen 10.1.1 IP Update 1 for a Spartan 3A DSP part?

 

At this time the multiply accumulate core doesn't support the part. The best way is to either let the tools infer it or manually instantiate it using the instantiation template available in the libraries guide.
