Modelsim Directory

[ALuPin]

Hi,

I have written a little .do-script with which
the VHDL files are compiled and the simulation is performed.

When I open Modelsim I have to go to
FILE --> CHANGE DIRECTORY and then I have to enter
the path of my simulation directory including my script.

How can I do this directory changing automatically at the beginning
of my script ? Is there any command ?

I would appreciate your help.

Here is the script

vlib work
# Compile base libraries
vcom util1164.vhd
vcom stdlogar.vhd
vcom io_utils.vhd
vcom mti_pkg.vhd
# Compile test vectors
vcom vec_gen.vhd
vcom ed_comnd.vhd

You can use an identifier to have a fully parametric script,
so that you can get rid of physical location of your HDL codes.

Example:

---- do script ----
....
set designlib /home/AluPin/sdram_chip
....
vcom -93 $designlib/sdram_ctrl/sdram_positions_arbitration/sdram_pos_arbiter.vhd
....

--- end of script ---

You can further parametrize your RTL simulation environment
by placing "$designlib" into a separate *.do script.
This way you can move the complete design directory to another
location. In this case you just need to update the *.do
script called in your script:

--- do script ---
....
do chip_global.do <-- designlib is defined here!!
....
vcom -93 ....
....
--- end of script ---

In "chip_global.do":
---
....
set designlib /home/AluPin/sdram_chip
....
---

.... and other necessary variables go there.

hi,

i solved that annoing problem modifing the modelsim.ini file that in my
computer is placed into the directory:

C:\Programs\Modeltech_xe\examples

the line that i added (or changed... i do not remember) is the following:

#########################

; VSIM Startup command
Startup = do wdir.do

#########################


and the wdir.do file is placed in the same directory with the following
command:

#########################

cd e:/work/fs/sim

#########################

hope this help
