LPM component replacement?

Hey everyone,

 

First time poster here, and i'm a newbie to FPGAs so please have some patience :)

 

Okay, here's my question:

 

I am working with someone else's code that was written for an Altera board. The code uses these 'LPM components.' Actually just one, a 12x8 multiplier. LPM library is for optimization purposes and not supported by Xilinx from what i understand. So my question is, can I simply write my own 12x8 multiplier or use another library component to replace the LPM version?

 

Thanks alot in advance!

Recent versions of XST synthesis do a pretty good job of inferring multipliers from HDL,

in FPGA's that have built-in multiplier or DSP blocks.  Otherwise the closest Xilinx equivalent would be

to use CoreGen to make your 12 x 8 multiplier.

 

HTH,
