Can the ISE Simulator be used to simulate designs that are targeted for non-Xilinx devices?
Behavioral Level – All technology-independent RTL can be simulated in ISim Gate Level (or Behavioral designs with technology-specific instantiations) – The ISE Simulator is intended for Xilinx customers only. This is why it comes with Xilinx libraries pre-compiled. Gate Level (Optional back-annotated timing) – The ISE Simulator is intended for Xilinx customers only. This is why it comes with Xilinx libraries pre-compiled and will only read in the SDF file that is produced by the Xilinx tools.
