Modelsim instance window error - Modelsim instance window error Hello, I have a problem with ModelSim Altera Starter Edition 10.1d (used with Quartus II 13.1). The project is based on Cyclone III, so I cannot use newer software. The problem started, when I moved the project to the newer computer with Win10. Reinstalation did not help. I'm receiving following errors when trying to import design via tcl sript: # **** Error: LoadCompleteQ cmd: Transcript::ViewSimPanes sim # **** ** Error: (vsim-4005) Invalid argument 'AssertionScope'. # ContextView configure: -filter <filter-list>** Error: (vsim-4005) Invalid argument 'UPF'. # ContextView configure: -filter <filter-list> # ** Error: (vsim-4005) Invalid argument 'AssertionScope'. # ContextView configure: -filter <filter-list>** Error: (vsim-4005) Invalid argument 'UPF'. # ContextView configure: -filter <filter-list> # while executing # "Structure::CreateWindow $dataset_name" # (procedure "Transcript::ViewSimPanes" line 26) # invoked from within # "Transcript::ViewSimPanes sim" # ("eval" body line 1) # invoked from within # "eval $p $tankNamespace " And # **** Error: LoadCompleteQ cmd: Transcript::ViewSimPanes sim # **** can't rename to "::.main_pane.structure.interior.cs.body.struct": command already exists # can't rename to "::.main_pane.structure.interior.cs.body.struct": command already exists # while executing # "$vsimPriv(windowmgr) ShowWindow $windowobj" # (procedure "Structure::CreateWindow" line 23) # invoked from within # "Structure::CreateWindow $dataset_name" # (procedure "Transcript::ViewSimPanes" line 26) # invoked from within # "Transcript::ViewSimPanes sim" # ("eval" body line 1) # invoked from within # "eval $p $tankNamespace " The simulation is running, but I cannot see a project structure window. I created a test project to investigate that. The whole code in project is: Main file: module Test_Project( A, B, AND_OUT ); input wire A; input wire B; output wire AND_OUT; assign AND_OUT = A & B; endmodule Test bench: `timescale 1 ns / 1 ns module TestBench(); reg A=1'b0; reg B=1'b1; wire AND_OUT; Test_Project uut( A, B, AND_OUT ); always #20 A = ~A; always #40 B = ~B; endmodule TCL file, that loads the script: #init_tk echo "Creating library" cd {D:\Projects\FPGA\Test_Project\simulation\modelsim} vlib ./work vmap work ./work #echo "Adding library" #vlib altera_mf_ver #vmap altera_mf_ver ./altera_mf_ver #echo "Compiling library" #vlog -work ./altera_mf_ver "D:/Software/altera/13.1/quartus/eda/sim_lib/altera_mf.v" echo "Compiling modules" vlog -work ./work "D:/Projects/FPGA/Test_Project/Test_Project.v" vlog -work ./work "D:/Projects/FPGA/Test_Project/TestBench.v" echo "Load/Simulate the design" vsim -L altera_mf_ver TestBench -t ns echo "Done." vsim -L altera_mf_ver TestBench -t ns echo "Done."

There is definitelly some compatibility problem, because I run the project with Modelsim Starter Edition 10.5b revision 2016.10 and it works perfectly. So my advice to other users would be to write a Cyclone III code in Quartus II 13.2 and test it in Modelsim 10.5b that is in a package with Quartus Prime. Replies: Re: Modelsim instance window error I am able to install ModelSim ALTERA STARTER EDITION 10.1d Revision: 2012.11 and run the simulation successfully. Below are the steps that I did. I just create a new project in Modelsim, added the Test_Project and the TestBench files that you provided. Compile both files. Run vsim -L altera_mf_ver TestBench -t ns Add wave and Run 2000 I think this is mostly a bad installation but you mentioned you have try to reinstall before, so I am stumped as to why you are still facing this issue. https://community.sw.siemens.com/s/question/0D54O00006mFTprSAG/modelsim-cant-open-structure-window Best Regards, Richard Tan
