txt file, optionally, you can generate it by right click in the Waveform View, select Export Waveform and choose the Files of type. which is ASCII format file and can also be displayed in third-party tools such as Modelsim and Active-HDL. The file is in a ASCII character-tab-delimited format. vcd file, optionally, you can generate it by right click in the Waveform View, select Export Waveform and choose the Files of type. which contains waveform data that can be displayed in third-party tools such as Modelsim and Active-HDL. When a run has been completed, valid information with changed debug configuration is displayed. When trace and trigger signals have been changed, the incorrect information is displayed. To make ModelSim show all delta cycles, WLFCollapseMode 0 must be set in the modelsim.ini file as.
You will not be able to see beyond delta cycle +1 without changing the configuration file. By default, ModelSim will only log an object’s value at the start and at the end of a timestep. You have the option of clearing the transcript (File > Transcript > Clear Transcript) if you don’t want to save the entire command history. You can save the transcript at any time before or during simulation. When you first open Reveal Analyzer, the information is displayed until you press run button. Show all delta cycles in the ModelSim waveform. ModelSim’s Main transcript can be saved, and the resulting file used as a DO (macro) file to replay the transcribed commands. trc file, which contains the waveform information acquired from previous runs. rva file, which can be used as input file when you reopen a Reveal Analyzer project you saved last time. rvs file, which is generated by Reveal Inserter and contains the settings that can be changed by Reveal Analyzer.Īfter debug, Reveal Analyzer generates the following files by saving the project: rvl file, which is generated by Reveal Inserter and is used to identify trace and trigger signals and storms the options. hub file, which is generated by Lattice Diamond's Place & Route Design process of the design implementation procedure and is used to sort the data coming from the different reveal modules. If you used a wave.do file to add signals when running the simulation, you must call it when viewing also, i.e.: vsim -wlf waveform.wlf -do wave.do And then.
Later you can view the by doing vsim -view waveform.wlf. 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.
#Modelsim save waveform configuration verification#
bit/.jed file, which is generated by Lattice Diamond's Export Files process of the design implementation procedure and is required to program the device. What I suggest you to do is save the waveform by using vsim -wlf waveform.wlf. 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. Four files are needed when debugging with Reveal Analyzer:
