I 've generated 18x18 block based multipliers using Synplify_pro tool. Now I want to generate logic based multipliers( which dont use blocks ). I 've no knowledge on the contsraint files used to generate multipliers using synplify_pro. Can any one let me know on how I can generate logic based multipliers.
The following is the .prj file used to generate 10x33 block based multiplier.
