Lorenzo, you must be pretty smart if you can solve the "worst nightmare
ever invented" in a mere ten minutes... :-)

Howdy Peter,

I interpreted his comment to mean that he wasted ten minutes on
just one aspect of the many that form the nightmare that is iMPACT.
And I have to agree with him. The tool sure works like it was
designed by someone that doesn't actually have to use it more than
once or twice. The rest of the Project Navigator (at least on 5.x),
while noticably better than iMPACT, is also very disappointing coming
from a company that produces such high caliber hardware.

Have fun,

Marc

Hi Marc,

Xilinx do welcome user inputs on improving the tools. You're more than
welcomed to let me know or open hotline cases for change requests on
Xilinx software tools. We all benefits from specific constructive
suggestions!

Best Regards, Wei

Ok, here are my suggestions for today.

1. Allow multiple installations of (different versions of) Xilinx
software on the same machine. Drop the use of the XILINX environment
variable - it's a PITA.

2. Add a "save project as script" command to the project manager.
This allows a user to use the GUI to set up their project options,
then save a shell script or batch file and then never use the GUI
again.

Regards,
Allan

Conflicting requirements. The XILINX environment variable is what
ALLOWS multiple installations. That's how the pieces of an installation
find the other related pieces, rather than some other version.

3. Add options to XST to allow defines, parameters and generics to be
set from the command line as well as from a project file.

Allan.

(Say) the value of XILINX is c:\xilinx42, which points to the ISE 4.2
installation.

Now run the 5.2 FPGA Editor
Start|Programs|Xilinx ISE 5|Accessories|FPGA Editor

It bombs 'cause it tries to use the wrong version of a library. It
doesn't have to bomb (since it can know where it is installed, and
doesn't need to look at an environment variable to find out), but
that's the way Xilinx wrote it.

> The XILINX environment variable is what ALLOWS multiple installations.


Could you explain that (using my example) more fully please?

(BTW, I have used the XILINX variable in the past to select different
versions within scripts, so I know what you mean, but I still think it
needs to be improved.)

Regards,
Allan

To make it more interesting, try to run both 4.2 and 5.2 fpga editors
at the same time (yes, I have wanted to do this), both run from the
start menu, without using
Start|Programs|Control Panel|System|Advanced|Environment Variables
to change the value of XILINX.

Well written software would do this without a hitch. The only reason
Xilinx software doesn't do it is because customers don't complain
enough. Well, I'm complaining.

Allan.

That may be the way it is implemented, but I believe Allan is asking
that they change the implementation. I know that I can have separate
versions of Netscape, Visio, MS Office and many other packages running
on the same machine. All I have to do is double click on the icon to
run them. No changes to environment variables or other system wide
changes.

Surely this could be done with CAD tools if the vendor really wanted to
make the change.

Allan,

For your point 2, it's already implemented in ISE6.1i with the
<project>.cmd_log file.

Again, thanks for the suggestions. And it's best for you to open a case
with the Xilinx support for the feature enhancement requests to make
sure we capture the requests with a actual case.

Regards, Wei
