LogiCORE DVB S2 FEC Encoder v2.0- Why do I get incorrect output on the encoder when using Virtex-6 in VHDL simulation?

Description

For LogiCORE DVB S2 FEC Encoder v2.0 I see incorrect data output on the encoder when using Virtex-6 FPGA and doing VHDL simulation regardless of if its unisim or simprims. Why is this?

Solution

There is an issue with the IP and doing VHDL simulation. This will manifest itself in the output from the core being incorrect in unism and simprims simulation. The workaround is to use Verilog simulation netlists for unism and simprim testing.

There are no problems with the NGC netlist generated and this will work on hardware.
