Why do I get a "Fatal: Error occurred in protected context" when simulating a Cyclone V PHY Transceiver in Modelsim?

I am using Quartus II 13.0sp1 (web edition) and need to implement a Cyclone V Native PHY Tranceiver for a Cyclone V GX. When I try and simulate my design with the Native PHY IP core or the Custom PHY...

Hi,

I can run the examples shown on:

https://fpgawiki.intel.com/wiki/Cyclone_V_Transceiver_PHY_Basic_Design_Examples

They run without a problem in Modelsim 10.1d which makes me think it is Quartus 13.0sp1 that is the problem.. Or I am not designing the Native PHY correctly.

What is the simplest method of getting parallel data from the FPGA to the high speed serializers through the HSMC connectors? I don't need any fancy reset or reconfiguration control - just need to serialize 40-bit parallel data (using the double width setting) at a very high speed. The 40-bit vectors are updated @20MHz (for example) and I need to serialize it @800MHz (40x 20MHz).

Cheers,

Alex
