NativeLink Simulation of DDR2, DDR3, and LPDDR2 Interfaces Fails for ModelSim AE and ModelSim SE

Description

This problem affects DDR2, DDR3, and LPDDR2 products.

When you attempt to simulate a DDR2, DDR3, or LPDDR2 design using NativeLink with ModelSim or ModelSim-Altera, NativeLink fails and reports a parameter not found error.

Workaround/Fix

The workaround for this issue is to open the generated .do script found in the ...simulation/modelsim directory in a text editor, and change the following code:

vsim -t 1ps -L altera_ver -L lpm_ver -L sgate_ver -L altera_mf_ver -L altera_lnsim_ver -L arriav_ver -L arriav_hssi_ver -L arriav_pcie_hip_ver -L rtl_work -L work -voptargs="+acc" dut_example_sim�

to the following code:

vsim -t 1ps -L rtl_work -L work -L altera_ver -L lpm_ver -L sgate_ver -L altera_mf_ver -L altera_lnsim_ver -L arriav_ver -L arriav_hssi_ver -L arriav_pcie_hip_ver -voptargs="+acc" dut_example_sim�

This issue will not be fixed.
