F-tile transceiver IP simulation
- 3 years ago
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."

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.
According to the PMA/FEC Direct PHY User Guide:
PDF link: https://cdrdv2.intel.com/v1/dl/getContent/683563
Page 219:
The F-Tile Reference and System PLL Clocks Intel FPGA IP is required for F-tile PMA/FEC Direct PHY designs. You must instantiate and connect this IP for simulation and compilation.
Page 189:
The F-Tile Reference and System PLL Clocks Intel FPGA IP must always connect to the F-Tile PMA/FEC Direct PHY Intel FPGA IP or protocol IPs. You cannot compile or simulate the F-Tile Reference and System PLL Clocks Intel FPGA IP as a standalone IP.
So, please check your testbench to make sure the Reference and System PLL Clocks and PMA/FEC Direct PHY are connected as illustrated in Table 96 of above user guide.
You can also generate an example design from the 'Example Design' tab of the F-Tile PMA/FEC Direct PHY Intel FPGA IP, then you can visualize the connection.
