ISE: Parallel Processing

[Martin Euredjian]

Is there a way to have more than one computer work on compiling a design?

I think the answer is "no".

In that case. Is there a way to send off the compilation job to another
machine?

I find myself writing embedded code (using an outside tool) or doing CAD/EDA
work while waiting for ISE to complete. Of course, everything slows down to
a crawl while ISE is working. It'd be nice to be able to use a different
computer on the network to do the crunching (it'd be nicer to have more than
one machine parallel process and do it faster!).

Any ideas, or am I thinking too far ahead?

The Solaris version of par (Xilinx place and route tool) can do
multiple iterations on multiple hosts (using the -m option to par).

In that case. Is there a way to send off the compilation job to
another machine?

I do this all the time. I have a server running Solaris or Linux where
I have scripts running through synthesis, map/fit, place & route,
static timing analysis, generating programming files, and even upload
the new fpga image to the device under test in the lab.

Hey, the Linux versionhas that too. I can use that to make an
extra process on the local machine in order to put a dual processor
to use?

I'm glad to hear that this is supported in the Linux version.
Unfortunately I haven't received mine yet.

The trick (at least on the Solaris version) is to write the same host
name twice (or whatever number of procesesses you want to run) in the
host file you pass to PaR, but with a different combination of upper
and lower case letters:

zener
zeneR

will then create two processes on the host zener.

Interesting. I didn't think this worked yet. It's pretty easy to do
this with scripts, so we
did not schedule the feature for 6.1i. Let us know how you got it to work.
