This article introduces the knowledge of "Building the uvm environment under Modelsim". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Download modelsim software

Download modelsim, which is the modelsim10.4 version. Download address: https://pan.baidu.com/s/1wnCwlQ2EblCkKHFOM6gEyw extraction code: 772l.

After downloading and installing, you can see uvm-1.1d in the installation folder, which is the version of uvm we are using. There is a uvm_dpi.dll file under uvm-1.1d/win64, which is the compiled uvm library.

two。 Write a document

Take "hello,world" as an example, write the uvm source file as follows:

`timescale 1ns/1ps

`include "uvm_macros.svh"

Import uvm_pkg::*

Module hello

Initial begin

`uvm_info ("info", "Hello worldviews!", UVM_LOW)

End

Endmodule

After writing an executive program under windows: run.bat.

There is only one sentence:

This is to run the modelsim script file sim.do.

The Sim.do file is as follows:

Set UVM_DPI_HOME E:/modeltech74_10.4/uvm-1.1d/win64

Vlib work

Vlog-L mtiAvm-L mtiOvm-L mtiUvm-L mtiUPF hello.sv

Vsim-c-sv_lib $UVM_DPI_HOME/uvm_dpi work.hello

Run 100

The first sentence is to set the uvm environment variable to specify the dpi location of the uvm.

The second sentence is to create a work working directory.

The third sentence is to compile the source file, and specify several compilation libraries through-L.

The third sentence is to perform the simulation, calling uvmKuuvm _ dpi.

The fourth sentence is how long to run: 100ns.

3. Execution

Double-click run.bat, and then call modelsim for compilation and simulation.

This is the end of the content of "Building the uvm Environment under Modelsim". Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
