QS之Intro

公司里用Questa Sim做仿真，其实跟ModelSim差不多，总结常用的命令如下。

1　　启动

vsim -gui

2　　编译 -- VCOM

vcom  

 [-2008 | -2002 | -93 | -87]　　Choose VHDL 2008, 2002, 1993, or 1987 [-explicit] 　　　　　　　　　 Resolve ambiguous overloads [-work <libname>] 　　　　　　 Specify work library <filename(s)> 　　　　　 　 VHDL file(s) to be compiled

 

3　　仿真 -- VSIM

vsim

 [-t [<mult>]<unit>]   Time resolution

 

4　　Example

# Clear former sim

quit  -sim



# Make library directory structure

if {[file exits work] == 0}

{

    vlib work

    vmap work work   

}



# Compile files
# Here set your own directory

set srcpath ../hdl

vcom -93 -explicit -work work $srcpath/spi_master.vhd



# Simulation commands

vsim -t 1ps tb_spi



add wave -noupdate -radix hex -group mut mut:*

configure wave -timelineunits ms

configure wave -namecolwidth 170

configure wave -valuecolwidth 75

configure wave -signalnamewidth 1



run 1 ms

wave zoom full

 

6　　configure wave

　　-signalnamewidth [<value>]

　　(optional) Controls the number of hierarchical regions displayed as part of a signal name shown in the pathname pane.

　　　　　　　 Can also be set with the WaveSignalNameWidth variable in the modelsim.ini file.

　　<value> — Any non-negative integer where the default is 0 (display the full path). 

　　　　　　　　1 displays only the leaf path element, 2 displays the last two path elements, and so on.
