To simulate the Stratix® II GX transceiver model in third party simulation tools, the following files are required for Verilog and VHDL designs.
For Verilog simulation: stratixiigx_atoms.v , stratixiigx_hssi_atoms.v, sgate.v, 220model.v
For VHDL simulation: stratixiigx_atoms.vhd, stratixiigx_components.vhd, stratixiigx_hssi_components.vhd, sgate.vhd, 220model.vhd.
These files can be found in the ..\quartus\eda\sim_lib under the Quartus® II software installation directory.
