Changing LUT input size in synthesize

Apr 12, 2007 1 Replies

Dear all, I'm doing research on FPGA's LUT input size. And i'm using synplify pro to synthesize vhdl/verilog to edf for virtex2 device. Do you know how to limit the LUT input size to 1, 2,3 in synplify pro?



And even, could I use 5,6,7,8 .... -input LUT in synplify pro (also using virtex2 device).



Many thanks for your help !



Regards, Yu



Hey Yu, I think you'll need to instantiate the LUTs in your HDL. Does the Synplify manual mention LUT input size? Cheers, Syms.
