USING MODELSIM ALTERA INSTALL
On your home system, installing Quartus II Web Edition will also install ModelSim®-Altera® Starter Edition. Reference: Quartus® II Introduction Using Schematic Designs pdf, 40pp, 2013 Note: I strongly recommend that every Quartus project have its own directory. Now you'll get rid of this 'altsyncram failed' message. Manually Forcing Inputs in ModelSim-Altera. hex in ModelSim work directory (type pwd). mif, so you have to open it in QuartusII and save as. just click on Simulate > Start Simulation > Libraries. If you are using Verilog you have to add the altera_mf_ver library, if you are using VHDL you have to use altera_mf library. try this convert_hex2ver.dll approach:
USING MODELSIM ALTERA FULL
replace the relative path to the full path of your.
USING MODELSIM ALTERA VERIFICATION
ModelSim is only a functional verification tool so you will also have to use Quartus II to complete timing analysis on your design before you can be sure it will work the DE2 hardware. If ModelSim starts the memory content with zeroes, try this: ENSC 350 ModelSim Altera Tutorial This is a quick guide get you started with the ModelSim Altera simulator. Now you'll get rid of this 'altsyncram failed' message. If you are using Verilog you have to add the altera_mf library, if you are using VHDL you have to use altera_mf_ver library. " Fatal: (vsim-7) Failed to open VHDL file "ram_data.hex" in rb mode.# ** Warning: (vsim-3010) - Module 'rom1' has a `timescaleĭirective in effect, but previous modules do not. However, i am now getting an error saying it is unable to load my data initialization file. Then i tried adding signals from my object window to my wave and running the simulation. on another forum, i found the vsim command, so i tried 'vsim -i top.vhd, ram.vhd' and it simulated successfully! Hi Kaz, thank you! Actually just after posting my reply earlier, i was able to get it to simulate with all the files. You need to make sure you got altera libraries compiles and appear in modelsim list. If you haven't waveform file you can start with an empty one, then after simulation add nodes to the waves. To run it type in modelsim command window : do file_name.tcl # simulate testbench architecture a, or any file
USING MODELSIM ALTERA HOW TO
is there some resource that would help me understand how to use these different things?Ĭreate a text file and save with extension. Therefore select ‘full visibility’ in the tab Optimization Options. Optimization improves simulation speed but during debugging not all signals and variables are visible. In case a licenced version of ModelSim/QuestaSim is used optimizations it is on by default. I've only ever modified the waveform directly in quartus and run simulation. In the ModelSim-Altera starter edition Enable optimization is disabled. I dont have much experience with using tcl or do. However for compile I was able to select multiple files like this and it compiled ok. also if i select multiple files in the simulate option from the toolbar i am getting the same error. so if i simulate just my top level entity file, i get an error saying it cannot find the instance of RAM. Hi Kaz, I am not seeing an option to simulate all the files in the WORK library. Many designers use tcl or do file to compile and run simulation at a single click. The nativelink is not a separate simulator but it launches modelsim from quartus (ready for your design), I never use it. It is divided into fourtopics, which you will learn more about in subsequent. This lesson provides a brief conceptual overview of the ModelSim simulation environment. When you compile, check what is the default library. ModelSim Tutorial, v6.4a 11 Chapter 2 Conceptual Overview Introduction ModelSim is a verification and simulation tool for VHDL, Verilog, SystemVerilog, and mixed-language designs. Ideally a testbench can be used to inject data into top level. You will then need to add waveform file by choosing your inputs and applying logic. Then you simulate any level by selecting from work.
USING MODELSIM ALTERA CODE
In principle you compile any source code into a chosen library which defaults to work. Is it a must that i have to have a test bench? or can i just create/modify waveforms in modelsim to simulate my design? How can i set it up so that i can simulate everything together? if i try to simulate my top.vhdl file, i get an error saying modelsim cant find my work.ram entities. I'm not able to simulate the WORK library itself. However, I'm unable to simulate the design. In ModelSim, I'm able to compile my design if i select all the files ( VHDL file with my RTL as well as the RAM.vhd which i make using the IP designer ). I want to simulate the design using ModelSim. I have a design of a simple edge detector that instantiates a few RAM blocks ( ALTSYNCRAMs). a lot of it talks about using NativeLink to simulate from within quartus but im ok to use modelsim, since im much more comfortable using the waveform editor. Sorry if this is a very basic question, but i couldnt find the answer in any of the altera documentation. Hi, I'm very new to using FPGAs especially ModelSim(Altera).
