This document is for information and instruction purposes. Next, edit the VI. Found the differences of these two tools below from Ref[1]. It includes writing, compiling and simulating Verilog code in ModelSim on a Windows platform. You can then perform an RTL or gate-level simulation to verify the correctness of your design. Afterwards you can open up the specific waveform/dataset. In digital electronics, an arithmetic logic unit (ALU) is a digital circuit that performs arithmetic and bit-wise logical. fdo ModelSim Script. The Synopsys VCS® functional verification solution is the primary verification solution used by most of the world’s top 20 semiconductor companies. The program must be run from /modelsim_ase/bin folder in order to dodge segfaulting. Use the Zoom->Zoom Full menu item in the wave window to expand the waveform display. ModelSim is a high-performance digital simulator for VHDL, Verilog, and mixed- language designs. ModelSim EE licenses must be located at a single site, i. Do not check the "Run gate-level simulation automatically after compilation" box. Most of this you will have to discover for yourself. 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. Starting in version 15. Additionally, limited-functionality editions of the Aldec and ModelSim simulator are downloadable free of charge, from their respective OEM partners (Microsemi, Altera, Lattice Semiconductor, Xilinx, etc. I assume that St0 >means strong0 and St1 means strong1. However, to either facilitate debugging tasks or check specific behavior of lower level components most of the time internal signals also need to be displayed in the Wave View window of ModelSim. Type project name. vwf", simulation may be fail. I tried to change my signal as a Analog signal in wave properties but nothing really changed. Even though you don’t have to use projects i n ModelSim, they may ease interaction with the tool and are useful for organizing files and specifying simulation settings.

Note the '-noupdate' makes adding a LARGE NUMBER of signals far faster but you need to call wave refresh when done. 3 Release Notes Archives Illegal assignment of null waveform in a subprogram to a non-guarded actual 'mux_out'. The ModelSim command interpreter is actually a Tcl interpreter with ModelSim specific functions added. In the Signals. Some of the windows display as panes within the ModelSim Main window, some display as windows in the Multiple Document. Add signals in the waveform window Use add wave to add selected signals, or all the signals in a selected region, to the waveform viewer. If you are able to run simulations using Modelsim, you should use Modelsim's waveform format instead of the FSDB format. ModelSim should open a window as in Figure 1. Inside the Signal window, users can high light signals they want to add in the Wave window, then click AddWaveSelected Signals or use AddWaveSignals in Region to. Figure 9: ModelSim Window -The rightmost panel is the test waveform To inspect the waveform generated, you may consider enlarging it. com 3 1-800-255-7778.
