how to synthesize the cores generated by the core generator in ISE using synplify? I add the .edn file into the project in the synplify ,but it has no effect.
EDN is already an EDIF file IT MEANS that is already SYNTHESIZED ..so you only need to ROUTE it to the final product that will implement it !
To do tho this it depends what is the ULTIMATE product enviroment you want to USE .XILINX ,,ALTERA ,, but certainly NOT SIMPLIFY !..simplify just PRODUCES an EDIF which you already have .,.Use ISE .. and import that EDN file to it !
then ROUT it .. and produce a PROGRAMMING file for the TARGET product !
