Modelsim Directory

Dec 08, 2004 2 Replies

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



vcom -93 ../../../sdram_ctrl/sdram_positions_arbitration/ fraction_sdram_numbers_fifo.vhd vcom -93 ../../../sdram_ctrl/sdram_positions_arbitration/ mux_fraction_fifo_outputs.vhd vcom -93 ../../../sdram_ctrl/sdram_positions_arbitration/sdram_pos_arbiter.vhd vcom -93 ../../../sdram_ctrl/sdram_positions_arbitration/ sdram_positions_arbitration.vhd



vcom -93 ../../../sdram_ctrl/valid_bytes_in_row.vhd vcom -93 ../../../sdram_ctrl/tristate_buffer.vhd vcom -93 ../../../sdram_ctrl/sdram_controller.vhd vcom -93 ../../../sdram_ctrl/sdram_ctrl.vhd vcom -93 ./mt48lc8m16a2.vhd vcom -93 ../../../sie_trans_fs/read_burst_fifo.vhd vcom -93 ../../../sie_trans_fs/crc16_8bit_in.vhd vcom -93 ../../../sie_trans_fs/sie_trans_fs.vhd



vcom -93 ./tb_sdram_ctrl_sie_fs.vhd vsim tb_sdram_ctrl_sie_fs do Simulationsplot_sdram_ctrl_sie_fs.do run 1200us -all

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

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

andrea
