A quick ModelSim tutorial

Let’s assume you have ModelSim installed and properly configured. Here

are the basic steps to simulation. These commands work within ModelSim

at the ModelSim prompt, or on your operating system command line. You

must be in the modeltech/examples directory to run the examples. (Go to

Licensing and installation if ModelSim is NOT ready to run.)

Use these commands at the VSIM prompt within ModelSim:

For more simulation exercises and lessons, choose one of the following

from the ModelSim Main window Help menu:

• Help > QuickStart menu > See an Example (button)

• Help > EE Documentation > EE Tutorial

Command Description

vlib work creates a work library for holding your

compiled designs

vcom counter.vhd

vlog counter.v tcounter.v

compiles the HDL source code, use vcom

for VHDL or vlog for Verilog

vsim counter

vsim test_counter

loads and simulates the design unit, use

counter for VHDL or test_counter for

Verilog

view * opens all ModelSim windows

add wave * adds all signals in the design to the Wave

window

force clk 1 50, 0 100

-repeat 100

(this command must be

invoked on one line)

forces the clock (VHDL design only) to

value 1 after 50 ns after the current time,

then to 0 at 100 ns after the current time

and repeats every 100 ns

run 1000 runs the design for 1000 ns

quit exits ModelSim (use quit -f to exit

ModelSim without confirmation)
