Hi,
I just found and tried to evaluate the xmil007 memory-intercae compiler for the Spartan-3 and the recent Virtex devices ... It seems to work quiet nice for the ballgrid devices fg320 and above but for the very common vc3s400pq208 and other none ballgrid-devices there are always errors like this one :
------------------------------------------------------------------
%Reserve Vrp & Vrn pins: Checked %Reserved pins:
Selected Design option: Full controler %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Unable to find the necessary attributes for all pins. Requested data pins: 64. Found locations: 0. Could not find the pins for all the data and dqs . Time:Sun October 10 14:32:52 2004
*************************************************************************--------------------------------------------------------------------
Is there anyone out here who has been able to use this approach to generate a ddr-1 memory interface for a Spartan-3 in a PQFP package ?
Reagrds,
Thorsten
