ModelSim Waveform Viewer for UniPHY External Memory Interfaces Shows Only clk and reset Signals

Description

ModelSim simulation of the example design for MegaWizard-generated systems displays only the clk and reset signals in the waveform viewer.

Workaround/Fix

The workaround for this issue is as follows:

  1. Open the existing <variant_name>_example_design/simulaion/<variant_name>_example_sim.qsf file in a text editor and add the following line to the file: set_global_asignment -name EDA_NATIVELINK_SIMULATION_SETUP_SCRIPT my_wave.do -section_id eda_simulation where <my_wave>.do is a file name of your choice
  2. Create a ModelSim <my_wave>.do file in the <variant_name>_example_design/simulation directory. Ensure that the <my_wave>.do file has the following content: “ add wave dut/<variant_name>_example_sim_inst/* run -all “
