Thank you for the tips.

I have finally found the problem. It was a non-English character in the folder name of the project! I am not sure why this caused a problem with Signaltap only but by coincidence I noticed that the project including Signaltap would run successfully if I copied the project to another folder so I tried changing the folder name and it worked.

​Hi,

Intel Altera only supports standard alphanumeric characters and underscores (_) in installation paths and project directory.

Examples of unsupported characters: \/:*?"<>|!£$%^&()

    Hi Anand, a parser to pinpoint wrong path is not so difficult to write, at almost jut test path string. Not forever just when path var is created.

    About catastrophic "&" behavior appear just on windows OS, Unix, Linux too accept also control character on path/file name. It is good taste of user not to do.

    If \ / character are not supported, how can we specify path?? Maybe one of two can be confused with escape sequences, but on path one of this is a standard.

    It is better prevent what can hurt code than leaving untested and not clearly stated

    Regards

    Roberto.
