Could some Xilinx ISE guru provide some hints for my problem ? I am
trying to synthesize a simple 4K RAM block with Xilinx ISE. About half-
way through execution, I get an error message, inside a Visual Studio
dialog box, stating that xst.exe ( the Xilinx synthesis executable)
has encountered a problem and would I like to debug ? The Xilinx ISE
is running
on a XP machine.
Any hints, suggestions would be of immense help.

Can you try synthesizing a much smaller RAM (say 128 words?)

Can you post your code?

What does the synthesis logfile say?

You haven't given us much to go on!

Cheers,
Martin

The entire 11.x tool chain has been, in my experience, an unmitigated
disaster. You might could try upgrading to the latest version, 11.4.
There's a chance it'll fix your problem. Then again, there's a chance
that it will create a new, unrelated problem, too. But at least if the
problem is moving around you can claim you've got movement on the
problem.

Xilinx tells me that 12.1 will be better, come April. Now if only all
_my_ customers were willing to sit around and wait for two extra
months.

I've had good luck with 10.1.

So did I, right up until I started a Spartan 6 design. Thus began my
life as a tool fighter rather than a logic designer.
