tcl commands in Altera Modelsim

Hi all!

I am using Altera Modelsim, which is tcl-based. I use the GUI.

In the console, when I type the command puts "a" I get not output:

ModelSim> set a 1

# 1

ModelSim> echo $a

# 1

ModelSim> puts $a

ModelSim> puts "a"

ModelSim>

Can anyone explain that?

Thx

    I just tried this under Windows 7 with Quartus 15.0 Modelsim 10.3d. I started a NIOS II IDE shell first, used 'which vsim' to confirm I was going to run the correct version of Modelsim, and then ran 'vsim', without the -gui option. The Modelsim GUI console output was: 

    
ModelSim> puts "Hello!"
ModelSim> echo "Hello!"#  Hello!

    The first "Hello!" was printed on the NIOS II IDE shell command-line.

    Adding the -gui option redirects the output to the GUI console.

    Thanks for posting your solution, it works great! :)

    Cheers,

    Dave

    When you start vsim, try to use the "-gui" option, like "vsim -gui"

    That is indeed the solution for me, thanks.

    Hello Dave,

    As I have neither a Mentor ID nor a service contract I would greatly appreciate if you would ask them.

    [edit]

    For now I launch Modelsim from the command line executing vsimk 

    
 intelFPGA_lite/16.1/modelsim_ase/linux/vsimk

    gets gets input from the terminal so I can use it but I need to use the terminal and transcript at the same time.

    I would do the same but I have a lot of automated simulations and thus many files to change. Apart from that I also take input using gets and I assume I will run in to some problems there.

    Yeah, I'd agree that there is a pretty good chance that you'll run into trouble there.

    Chances are Mentor have been asked this question in the past. If you have a Mentor Site ID and service contract, just file a service request. If you do not, ask me, and I'll file one ... since I am interested in the answer :)

    Cheers,

    Dave

    I encountered this issue a long time ago. If you compare "echo" vs "puts" on a Linux version of modelsim, you will see "puts" output going to the terminal that launches the Modelsim process, whereas "echo" prints to the Modelsim console output.

    I never bothered to figure out how to redirect puts, I just used echo in my scripts :)

    Cheers,

    Dave

    I have encountered the same problem, were you able to find a solution?

    you'd have to find a tcl channelid for the ModelSim console. i'm not sure if there is one.
