6.3i NetGen, Timing Simulation - NetGen is not writing out INIT attributes for ODDR and IDDR if non-default values are used

Description

Keywords: timing, simulation, SimPrim, ERROR, ModelSim, NC-VHDL, NC-Verilog, Virtex-4, VCS, ODDR, IDDR, INIT, attribute

Urgency: Standard

General Description:
When I use non-default values, NetGen does not write out INIT attributes for ODDR and IDDR. This prevents back-annotated models from compiling.

Solution

This problem has been fixed in the latest 6.3i Service Pack available at:
http://support.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 6.3i Service Pack 1.
