Re: "Launch hdl Simulator"??????

inform_won · ‎04-14-2008

Environment:

EDK 10.1
ISE 10.1
ModelSim 6.3c PE
using edk92i_ctt.pdf

The following are pre-setup:

Environment Variable: MODELSIM ---> pointing to the location of modelsim.ini (with the following modification in the file to allow using smart models)
---------------------------------------------------------------------------------------------------------------------------------------------

Edit the statement Resolution = ns and change it to Resolution = ps.
Comment the statement PathSeparator = / by adding ; at the beginning of the line.
For Verilog designs, enable SmartModels by searching for the variable Veriuser and change it to:
- On Windows: Veriuser = $LMC_HOME/lib/pcnt.lib/swiftpli_mti.dll
Search for the [lmc]section and remove comments from the libsm and libswift definitions according to your operating system as follows:
- On Windows, remove the comments from these lines:
  libsm = $MODEL_TECH/libsm.dll
  libswift = $LMC_HOME/lib/pcnt.lib/libswift.dll

----------------------------------------------------------------------------------------------------------------------------------------------

I am following the instructions at edk92i_ctt.pdf (p75) and made some modifications on the system_wave.do as follows:

#
#  Display IP and peripheral ports
#
# do jtagppc_0_wave.do
# do xps_bram_if_cntlr_1_wave.do
# do plb_bram_if_cntlr_1_bram_wave.do
do RS232_Uart_wave.do
# do Push_Buttons_Position_wave.do
# do SRAM_wave.do
# do ppc405_0_iocm_cntlr_wave.do
# do isocm_bram_wave.do
# do ppc405_0_docm_cntlr_wave.do
# do dsocm_bram_wave.do
# do SRAM_util_bus_split_0_wave.do
# do clock_generator_0_wave.do
# do proc_sys_reset_0_wave.do
do test_ip_0_wave.do

I tried cleaning simulation, then regenerate Simulation HDL Files, modified the system_wave.do file. After several clicking the "Launch HDL Simulator", the following is the output:

At Local date and time: Mon Apr 14 16:01:12 2008
 xbash -q -c "cd /cygdrive/c/IWC_Projects/Module1/; /usr/bin/make -f system.make

WITHOUT displaying MODELSIM!!!

Can anyone tell me how to fix this???

I am not sure why modelsim does not open from the XPS GUI when you select "Launch HDL Simulator...". However, there are two things you can try:

1.) Check the system.log file in you edk project directory to see if there is any additional information/errors that did not print to the GUI console. Sometimes an error might occur that is shown in the system.log file that may not print to the GUI console screen.

2.) If there are not any issues seen in the log file, you can always open modelsim standalone and cd to the .do file of interest and run the file from modelsim to see if this works.

centaur19 · ‎04-15-2008

Here is another thought to fix this:

Can you check if you have the modelsim executable in the %PATH%? If not, can you add it?

For example,

PATH = %PATH%;%MODEL_TECH%

MODEL_TECH = C:\Modeltech_6.3c\win32pe\

There is one error during compilation process of the libraries. It is found on the compedklib.log (is this the system.log that you are refering to?) in the edk folder.

I tried running the ModelSim in standalone, running the necessary do file to proceed with the simulation.

modelsim>do system_setup.do
# Setting up simulation commands ...
# **********************************************************************

Next, I compiled, resulting into an error.

modelsim>c
# ** Error: (vmap-20) Cannot access for writing file "c:\Modeltech_eval_6.3c\modelsim.ini".
# Permission denied. (errno = EACCES)

I observed that there is one modelsim.ini in the edk folder that is rewritable, the one that is in the modeltech directory is not.

Do I need to modify the write permission to the modelsim.ini that is located in the modeltech directory?

What I have are the following:

PATH = C:\Modeltech_eval_6.3c\win32;C:\Modeltech_eval_6.3c\win32pe
MODELSIM = c:\Modeltech_eval_6.3c\modelsim.ini

I checked, and the executable ModelSim is found on the win32pe folder.
The modelsim.ini in the modeltech folder is read-only.

Should I just add the path you specified?
Should I make the modelsim.ini rewritable?

You may want to set the modelsim.ini to the one in the folder where you have compiled your EDK libraries. And try setting the environment variable MODEL_TECH as I suggested.

Hello,

I have the same problem now. I did a design with EDK 9.2i latest Service Pack, and it worked, I could start simulation out of the EDK. Now I installed 10.1 and I get the same as above - nothing.

The message is displayed, but Modelsim does not start:

At Local date and time: Fri Apr 25 09:18:57 2008
xbash -q -c "cd /cygdrive/c/work/XILINX101/ml505_bsb_std_ip/; /usr/bin/make -f ml505_bsb_system.make simmodel; exit;" started...
Done!

I did set the Environment Variable manually in Windows, I got no errors in compiling the libraries, and I get no errors in comiling the design (i.e. generate bitstream)...

I use: EDK 10.1

Modelsim 6.3c SE

In EDK in "Project -> Project Options -> tab HDL and Simulation" Modelsim is marked.

Any help is appreciated!

Thanks,

Chris

... i forgot: I am able to start ModelSim alone and to load and simulate the design.

Thanks

Chris

centaur19 · ‎04-25-2008

Chris,

Have you tried setting all the environment variables listed above?

44026 · ‎04-28-2008

Yes, I think so...

What I did are the following:

On desktop:

right-click on "My Computer" -> "Properties" -> "Advanced" -> Button "Environment Variables"

In the top Window named "User Variables" I added two Variables, it then kind of looks like:

Variable | Value

______________________

MODELSIM C:\Modeltech_6.3c\modelsim.ini

PATH C:\Modeltech_6.3c\win32

(there are couple of other Variables, too, they've been there before)

I guess that is what you are referring to? If not, which file do I have to edit to get it run?

Thanks

Chris

44026 · ‎04-28-2008

Okay. I somehow got it...

I added the MODELSIM Variable today, (MODELSIM C:\Modeltech_6.3c\modelsim.ini, my last post) and now, after finally rebooting my computer, it works.

But it works only once per session. After clicking on "launch hdl simulator" Modelsim opens for the first time and I am able to simulate. After closing Modelsim, I tried to simulate again, but nothing happens. Even when I close the Project and open it again or opening another Project it won't help, Modelsim just doesn't start. Only after closing the whole XPS and open it again, I am able to load modelsim again, and again only for one time.

That's strange, isn't it? Do you have any suggestions on how I can fix this?

Thanks

Chris
