Dear friends i am now converting synplify project to the Xilinx environment. I need help on the constrain conversion from Synplify 7.5 to XilinxISE6.2i.


  1. What is the equivalent constrain of the "defineinput_delay" and "define_output_delay". is "pad to setup" delauy in the Xilinx is equivalent to this. Also there is a refeence to the clock in the constrians.

get cgd.pdf from xilinx website and read it, it helps :) no really the CGD.PDF is VERY important document explaining all the constraints
