BLUE SIGNALS IN MODELSIM ALTERA INSTALL
Please install ModelSim-Altera which is included with the Quartus II installer, or use the Quartus II Simulator instead by selecting "Simulation > Options > Quartus II Simulator" 1) I tried to generate the clock signal like this: here is the screenshot: But doing so it does not work, num1 is the first number to be added num2 is the second number s, the result. Then, when clicking the button for launching Modelsim, it starts doing it's job, but ends up with Hi guys, I tried to apply the stimuli using modelsim to the sequential adder that I described in vhdl. However, I can start Quartus, create a project, synthesize it, fire up the simulation window and configure the in signals. Running Quartus in 32-bit because I get lots and lots of problems otherwise. I've tried also $bitstoreal but then I would have to transform it to a 64bit number and consider the exponent and so on ( see wikipedia), so its definitely not an easy way to do that.Installed Quartus 13.0 with Modelsim in Fedora 22 64-bit. Then you probably see something similar to this: In the left hand window, you can now see the standard library. You can start modelsim with the command vsim. I tried to create a real signal in my testbench: real my_number1_real = (my_number1*(2.0**-4)) īut then all I can see is -0. This is a really quick introduction to modelsim. ModelSim Altera Starter Edition does not have this option on its GUI, so I thought I could maybe create a real signal in my testbench, related to the fixed-point, and then track this number. MORE THAN A TUTORIAL - A DEMO QUARTUS II / MODELSIM MODELSIM ECE232 Altera/Modelsim Tutorial Design an 8 bit CLA Adder Delay. To simulate the circuit we must rst specify the values of input signals, which can be done by drawing the input waveforms using the Graphical Waveform Editor. It shows the input and output signals of the designed circuit, as depicted in Figure8. When I used Cadence tools, I could click in the signal waveform and choose to 'create expression' and simply create a new signal: (my_number1*(2.0**-4)) an Objects window appears in the main ModelSim window. I would like to see -0.5 and 0.5 for my_number1 and my_number2 respectively. In order to make it easier to verify the values, I would like to see the real numbers they represent in the waveform.įor example, lets say: // 1bit signal, 4bits integer, 4bits fraction I'm using signed fixed-point numbers in my code.
