Xilinx PCIe core vs. Icarus Verilog

"Xilinx provides you with the ability to evaluate the functionality of PCI Express 1, 4 & 8 Lane Endpoint cores using MTI precompiled functional simulation models."

You don't get access to the Verilog. And it's unclear if you get the RTL for the purchased version either. (One didn't for the PCI core.)

You can understand that Xilinx would lock it to their part.

RTL costs extra.
