Dear Support,
I am learning how to simulate Nios II with Modelsim Questa. I am new to Nios II, and Questa.
it is great to find AN 351 which is called Simulating Nios II Embedded Processor Designs.
it is a little disappointed that AN-351-1.4 is based on
The Quartus® II software version 11.0 or later
■ ModelSim-Altera Edition version 6.6d or higher
■ Nios II Embedded Design Suite version 11.0 or later
Is there a newer revision of a similar application note that can be used a tutorial of simulating Nios II?
I am using Quartus PRO 21.3,
I followed the document step by step. it did run the simulation on the Questa.
Here is the Transcript console dump. the problem is when I add wave signals. it couldn't find any signals. always says, No objects found matching
--------------------------------------------------------------------------------------------------
add wave -position insertpoint sim:/niosii_system_tb/niosii_system_inst/*
# ** UI-Msg: (vish-4014) No objects found matching '/niosii_system_tb/niosii_system_inst/*'.

It is very likely that I missed something. could anyone give me some hint to trouble shoot my simulation environment. appreciate your help.
as an aged newbie, it is really painful to learn from scratch
add wave -position insertpoint sim:/niosii_system_tb/niosii_system_inst/*
# ** UI-Msg: (vish-4014) No objects found matching '/niosii_system_tb/niosii_system_inst/*'.
