You only need to write a good design file and import the testbench file directly into ModelSim to compile the simulation. It does not require synthesis or placement and routing. vcd file during the simulation.Ĥ.11 Perform timing simulation in ModelSim-Altera. vcd (Value Change Dump File) files from ModelSim for PowerPlay Power Analyzer analysis in QuartusII, you can enter commands in ModelSim:Ĥ.10 The Tcl script file instructs ModelSim-Altera to monitor the output signal in the Tcl script file and write it into the. Specify the directory \\altera\verilog\\, click OK Ĥ.7 Click the Design tab, in the Name list, click + to expand the work library, and select the design entity corresponding to the standard delay output file, and click OK to complete.Ĥ.8 If you want to simulate high-speed circuits (including HSSI, LVDS, PLLs, etc.), click the Others tab, enter +transport_int_delays +transport_path_delays in Other vsim options, and click OK to complete Ĥ.9 To directly generate. Click the Library tab, in Search Libraries (-L), click Add.ī. Tip: If you are using the test bench file as a design stimulus, then in the Apply to region box, starting from the top-level design file, point the path to the instance in the test benchĤ.6 If the simulation is a Verilog design, specify the precompiled libraries (ModelSim pre-compiled libraries)Ī. In the Add SDF Entry dialog box, click Browse, the Select SDF File dialog box appearsĬ. The Simulate dialog box appearsĤ.4 If it is a simulated Verilog language, click the Verilog tab and fill in 0 in the Error Limit and Rejection Limit in Pulse Options.Ĥ.5 If the simulation is a VHDL design, specify the. Tip: is the name of the global reset signal, is the global power-on signal, and is a time value, which is between 0 and the actual start time of the simulation.Ĥ.3 In the Simulate menu, click Simulate.
#MODELSIM ALTERA SIZE CODE#
Methods as below:įor Verilog, before the simulation, add the following code to the testbench file:įor VHDL, run the following commands before simulation: Important note: It is strongly recommended to set the Time scale to the femtosecond ps level during RAM simulation!Ĥ.1 Compile Verilog or VHDL output files and testbench files in the same way as functional simulation.Ĥ.2 If your design includes global reset or global power-on signals, and you have not done so, you can create these signals in Verilog or VDHL output files. Perform timing simulation with ModelSim-Altera In the Name list, click + to expand the work library, and select the top-level file to be simulated (usually testbench)ģ.3 Perform functional simulation in ModelSimĤ. In Search Libraries (-L), click Add to select the appropriate libraryĬ. If you want to simulate a Verilog HDL design file, specify the ModelSim pre-compiled library Repeat the above operation to compile the testbench fileĪ. vho files as functional simulation, you must compile before the following operations.Į. Select the work library under the Library listĬ. Perform functional simulation with ModelSim-Alteraģ.1 Compile Verilog or VHDL files and Test Bench files (if you use testbench)ī. Tip: If you want to run Modelsim independently from QuartusII, the library file name must be work if QuartusII automatically runs Modelsim, the name of the library is automatically named ModelSim_work and is located in the process directory of Quartus II.ģ. Enter the name of the library in Library Name Under the Create option, select a new library and a logical mapping to it.Ĭ. File->New->Library, a dialog box for creating a new library appearsī. If you want to perform timing simulation, the project directory must be set in the directory containing. Tip: If you want to perform functional simulation, the project directory is the directory containing the design files
#MODELSIM ALTERA SIZE SIMULATOR#
If you want to perform power consumption estimation, make sure to select the appropriate parameters in the Settings dialog box under Simulator Settings.Ģ.2 Start Modelsim software, select the project directory: File->Change Directory. sdo (standard delayed output files), you only need to run Start EDA Netlist Writer. Note: If you have already compiled the design and want to regenerate. This ModelSim version supports all Altera devices supported by Quartus II.ġ.2 To automatically run EDA design input, synthesis, simulation, or timing analysis tools from the Quartus II software, you must specify the location of the executable file of the third-party EDA tool by clicking Options on the Tools menu and then clicking the EDA Tool Options option.Ģ.1 If you want to perform timing simulation, you need to generate Verilog (.vo) or VHDL (.vho) output files.ī. Establish a ModelSim-Altera working environment

If you have any questions, please feel free to communicate in the FPGAKey forum.ġ. The article is relatively long and requires patience to read. Today, I will introduce you to the simulation process of the ModelSim-Altera version.
