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.
