ISE 6.1 with synplify : pin assignments

Nov 16, 2003 1 Replies

Hi, I'm using ise 6.1 to write, synthesise and implement my designs. I'm now trying to use synplify to synthesize without leaving the ise gui. Everything works fine, except that xilinx doesn't seem to pass the .ucf file with my pin assignments to synplify. The resulting .edf file doesn't have any constraints associatted with it, and ise cannot use the .ucf with the .edf. Is it possible to still use the xilinx constraints editor to generate the .ucf, or I absolutely need to open synplify and recreate all my constraints in their scope editor?

Synplify uses an SDC file to define the pin location, type, timing constrains etc. After synthesis it generate a UCF file for the EDIF file it generated and this can be used with Xilinx tools.

You should probably read the documentation for Synplify synthesis flow.
