Looking for DSP48E1 in 2014.2 Vivado IP Catalog

Jump to solution

I am trying to get to the DSP48E1 in the 7K325.  In the past, I have used Coregen

to access the IP.  In Vivado 2014.2 (and ISE14.6)  the only thing I see is a DSP48

Macro 3.0(Rev6.0).  When I open the Macro, I don't see the configuration of the DSP48E1

that I am looking for (specifically the pattern detector).

 

Can you tell me how I can instantiate the DSP48E1 via the DSP48 Macro, or if there is

a different approach to instantiation of the core?

 

Thanks,

Hello,

 

Right, the DSP Macro doesn't support the pattern detector.

 

You will need to instantiate the primitive directly. See UG768 for a template from which you can start from. They may have been added to the language templates by now as well (I'm not sure).

Yup, it looks like the language templates in 2014.3 Vivado have DSP48E1 instantiations/macros now.
