Using cmd line when multiple quartus versions installed

when you open up Quartus GUI on Windows, it sets the QUARTUS_ROOTDIR environment variable to that version. QUARTUS_ROOTDIR is used in the PATH environment variable, which is how the command line finds your executable applications

so to change the version of Quartus used by your script, set the QUARTUS_ROOTDIR to the appropriate location between each quartus_sh command

now that i think about it, this may require a bit more work because i'm not sure that PATH will change based on QUARTUS_ROOTDIR being changed in a shell

either way you should get an idea of how you can solve the problem

You cannot do this within Quartus, but you should be able to write a script to achieve what you want. For example, you can have the script change your search path so that when you type quartus_sh, it either finds it from the 9.1 or the 10.0 directories (for example).

If you want to switch automatically based on the project, you will need your script to first get the LAST_QUARTUS_VERSIOON from the QSF, and use that to decide which EXE to call. It should be easy to do using grep/awk or using some higher level scripting language like Perl, Python (or Tcl).

Hope this helps.

First have a look here, maybe it could help :

Good luck.

okay!

Combining all these I'll this is the plan:

- parse qsf to see what quartus version is needed (tricky cause i sometimes use a tcl script to generate the qsf...)

- try to list the installed Q2 versions and find their exe's

- run the right one if available...

If you are on Windows, an easy hack to use is to use the old "subst" command. Basically, you define a new letter mount to basically link to the different versions of Quartus, such that you can use a constant absolute path to Quartus.

Basically, you can add "z:\quartus\bin" to your search path (PATH) and then, based on the QSF setting, you dynamically change what Z: points to:

subst z: c:\acds91_path

or

subst z: c:\acds100_path

such that z:\quartus\bin\quartus*.exe are always the EXEs you use, only they magically point to different versions of Quartus.

You use Links to do the same on Linux.

Hope this helps.

hi,

I have written a script in ticle (tcl) to create, compile and program the altera's device cyclone II.

First two operations means create and compile design is working fine but when I am adding command to program the device it is showing errors that

"Invalid command name quartus_pgm "

while executing

unknown_original quartus_pgm -c USB-Blaster -m JTAG -o P"

please give me some solution.

the script which I am using is shown below.

basically I want to program the device from the script itself.

//////////////////////////////////

load_package flow

project_new test3 -overwrite

# Assign family, device, and top-level file

set_global_assignment -name FAMILY CycloneII

set_global_assignment -name DEVICE EP2C70F896C6

set_global_assignment -name VERILOG_FILE mux2_1.v

set_global_assignment -name TOP_LEVEL_ENTITY mux2_1

# Assign pins

set_location_assignment -to clk Pin_AD15

set_location_assignment -to reset Pin_T29

# compile the project

execute_flow -compile

# Other assignments could follow

quartus_pgm -c USB-Blaster -m JTAG -o P;mux2_1.sof

project_close

/////////////////////////////////////////////////////////

Thanks

Quartus_pgm is not a Tcl command. I believe you can access the command via execute_module ( you will need the -args option to specify the extra commands ), but if not, you need to use Tcl's 'exec' command or Quartus improved 'qexec' command.

Please use 'quartus_sh --qhelp' for details on the commands.

thanks for the reply.

but I want to ask that it is possible to program a device using a script.
