F-tile transceiver IP simulation

Hi Sir

I have checked the user guide, out_systempll_clk_ and out_refclk_fgt_ ports are not supported for simulation, and there is no current plan to support this.

There is a small note that mentioned this in the User Guide (page 110 and 222):

"Ports ending in "_link" must connect to the F-Tile Reference and System PLL Clocks Intel FPGA IP. These ports cannot be simulated."

PDF link to this user guide: https://cdrdv2.intel.com/v1/dl/getContent/683872

The understanding is that the System PLL outputs are not visible in simulation, but they are operating "under the hood". This would explain F-Tile PHY functionality even though the System PLL *appears* to not be functional in simulation.
