Webpack 9.1 problems with Impact on parallel cable

I've tryed ISE9.1 SP1.. and it crash!!! Then I come back with ISE8.2... and I can't open my old projects!!!

This is because they changed the format for the project file again. If you start up ISE9.1, it loads your most recent project by default and automatically converts it to the new format, which cannot be read by ISE8.

There's a yellow leaflet in the box to warn you about this. Of course, if you use WebPack, there's no box... :)

Try figuring out what the address is going to be after that...

I think the old version was saved as a .zip somewhere. So it should be possible to recover.

And the dialog box asks permission before converting the project. It also asks permission to save the old version (I think) and tells you where it put it, but I didn't pay attention to that. I can easily load that particular project from the Internet again if I need to, so I wasn't worried about that.

Your projects should be in some sort of source-code control system, which will easily allow you to go back to any arbitrary version.

Not everyone knows what a source control system is. As an example, I use this one:

As Francesco seems to be on windows, I'd also suggest this:

If Francesco was using subversion, then he would recover after:

svn revert projectname.ise

Or a couple of mouse clicks using tortoisesvn.

Would have been much easier and faster than posting to comp.arch.fpga.

Hope that helps.

I don't think is so simple Phil... I did backed up my project before use 9.1! Yes ISE 9.1 for default open your old project but also ask you "This project was made with an older version of ISE do you want to open?" (or a similar message) And I pressed "NO"... Maybe ISE 9.1 said Did you pressed NO? I don't care I'll open anyway.. I'm not the only person in my company having this sort of problem and we are very sceptic on 9.1.. and waiting now for the SP2!

I belieave that you guy at Xilinx are excelent engineer... but this sort of negative feedback must be taken seriously from you. It is actually the first time in 6 years that I'm starting to think to swtitch to Altera!

Francesco,

I'm a little person at Xilinx. I've designed using Xilinx FPGAs for about

15 years, and have worked for Xilinx for less than a year. I have much more experience giving feedback than getting feedback. As a long time user of Xilinx's software and FPGAs, I have given feedback to Xilinx in many ways and on many topics. Xilinx, as a whole, has listened well and has taken this feedback seriously. I don't think that I was listening well to your feedback.

Thinking as a long time user of FPGAs, I replied to Andy Peters comment to suggest a specific source control program. Bad things happen. Not only can software behave badly, and not only Xilinx's software, but also I make mistakes and need to recover from them. A source control program allows for quick and graceful recovery from many of these problems. I have been suggesting use of source control programs (cvs, svn and many others) for years.

I used your problem as an example of why using a source control program would be a good habit. This was rude of me, I'll try to listen better in the future, please forgive me.
