Hi,

I just compiled a pipelined multiplier (Variable Parallel Virtex
Multiplier v1.0.2) out of the Xilinx CoreGen with FPGA Compiler 2
(v3.4). According to the Xilinx Data Sheet it can do up to 143MHz for a
16x16 multiplication - the FPGA compiler reports a maximum frequency of
26MHz (more than 5 times less).

Any ideas on what I'm doing wrong there?

Thanks,

Andreas

Guys,

I'm running Max+2 v10 on an 850 MHz Athlon with win98,
256M ram.

I've been compiling designs targeted at a EPM7128S for
months with no problems (I'm not sure if this was with
the Quartus fitter, but I definitely hadn't turned it
off).

I recently tried compiling a small test design targeted 
at an Acex 1K30 and had to turn the Quartus fitter off
or it would crash.

?

I'm waiting for the new version of Quartus which should 
be able to target the Acex family to see if that's any
better (I think this is just out).

Nial.

Andreas -

Cores that are instantiated by CoreGen do not need nor use synthesis to be
implemented. So I find your statement "Compiled...with FPGA Compiler 2..."
to
be very puzzling. In addition, there are newer versions available for
download from the IP center at xilinx.com.

Perhaps you should consult the Coregen FAQ at support.xilinx.com?

Best Regards -

Mark

Cae vendors like to torture their best customers license games.

I am using many flexlm licensed applications on my win2k machine.
However, flexlm runs on a network server here, so I am immune
to the effects of changes to my own machine.

When you make any change to the machine running the flexlm server,
you can easily cause a mismatch with your existing licence.dat file.
Go to the vendor's web site and fill out a form requesting
an updated license.dat file.

There are three versions of VCS that I know of:

VCS Express       Fast       cheapest     (?  $8K )
VCSi              Faster     not as cheap (? $15K )
VCS               Fastest    not cheap    (? $40K )

I was able to compile Russell's code with no problems, on a w2K machine.
I'm wondering if there is some subtle issue with W9x machines, perhaps
OS-level parameter or file location declarations.

Anyone out there able to correlate MAX+2 go/no-go to

I tried the same acex design on my pc with w2k, and it works ok now.
Obviously not much testing is done on win95/98.

Ralph,
     There is no "better" language unless you start comparing nuances that
are mostly the realm of the expert.  In the end, either languages will
suffice.
     There are some things to consider, though.  For example, what tools are
available for your use already?  If your company has VHDL tools, then why
choose Verilog?  If your company has no tools, then make a decision based on
quality and cost of new tools.  If there are Verilog experts at your
company, then you may want to choose Verilog so that you can take advantage
of their expertise.  If your regional area is populated with companies who
mostly use Verilog, then why choose VHDL?
     Since both languages will do the job adequately, make a sound business
and technical decision.  Get your feet wet and comfortable with one language
and then down the road, tackle the other one.  It isn't that hard to switch
from one to the other.

Most likely you are driving it through some combinatorial logic.  Put 
registers immediately before the multiplier inputs to have a shot at 
meeting the quoted performance.  Also, make sure you set time 
constraints for your place and route, otherwise the tools just find a 
route without doing any optimization or checking for timing.

Does anyone know what Xilinx FPGA's are supported by the Xilinx Student

that it only supports the XC4000 family limited to XC4010 and below and
Virtex XCV50, but it doesn't say that they are the only support FPGA's.   I

from what I've heard on other newsgroups the problem is that win2K 
powerdown the nic if if it isn't connected to a network. 
A solution that is supposed to work is to make a loopback plug, 
(as far as understand just a rj45 plug with rx connected to tx) 
so that it thinks it's connected to a network.

I've a fair bit of experience with VHDL and have hacked some Verilog.

Everyone tends to prefer 'their' language, but if you think you'll
end up using both I think the consensus is that it's easier to move
from VHDL to Verilog. Having said that VHDL probably has a slightly
steeper learnign curve.

Hi!

I have questions. I have Xilinx Foundation F1.3.

I want to install this software on Win2000 system. I have no problem with
instalation, but when I wanted to compile project I couldn't do it because I
have error (bad Host id). I check my Host Id under the Win2k. It was
different from Host Id under Win NT 4.0 - Why? I have license on number of
net card (flexlm).

What can I do to work on Win2k?
