Questa Sim之Command

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
set srcpath ../hdl

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

# Simulation commands
vsim -t 1ps tb_spi
