Getting floating license

[Altera_Forum]

Hi, 

 Assuming one starts two compilations at same time where only one floating license is available. Does the Quartus II wait one process until the license becomes available, or just end with license error?  Regards,

[Altera_Forum]

no, quartus and others will report that the requestes licence is not available and stop. 

sorry but i am not aware of something like a commandline option or anything else that tells quartus and other tools to wait for a licence.

Hello MSchmitt, 

 Thank you so much for your answer. I will check the documents if the option is available.  Regards!

Usually it stops, but if it can't get the license at one specific moment (synthesis I think) it will continue but generate a time limited .sof file, with a simple warning buried somewhere in the console messages. It happened to me a few times and it can get very frustrating because you don't realise immediately that the .sof file hasn't been updated, and you are still trying to download the old one.

Daixiwen, 

 Thank you for your answer. It seems to need improvement!

I think that the obvious solution recommended by Altera is to buy more licenses ;)

[Altera_Forum]

oh YES Daixiwen ! 

This behavioral (TRAP :mad: ) will exist forever and be a pain like the A20 gate ... today, tomorrow and the day after ... :(   (and it happens not only by the altera newbies) ;)

and the only force we users (customers) have is to drop a licence. 

they get the money we get the bugs (Q 10.0)

In recent versions of Quartus, there is a checkbox in the Tools->License gui that will make the tool wait for floating licenses, so the tool will pause the compile and poll the license server until a license is acquired and continue rather than generating time-limited sofs

:p i'm always learning something ;)

It wasn't there last time I checked, but I have to admit is was a long time ago ;) 

Now the question is why is this optional, and not enabled by default?

[Altera_Forum]

it seems that you are not the only one last time checked this page :rolleyes: , maybe even those altera people who deceide what is default too ;) ... or why do you think they didn't made it default ? :D

is there a tcl command for this that can be put in the qsf-file or an argument when using quartus_sh?
