Last ISE version that supports XC95xxXL ?

Hi

can someone suggest what version of ISE would be best candidate not to
fail on XC95xxXL fitting?

ISE 8.2SP3 fails badly - I was hoping not have to install older
versions and check with WebFitter, but: "WebFITTER has been replaced by
ISE WebPACK" !!!!

and latest ISE fails badly with XC95xxXL as target, the same VHDL
design reports different number of pins being used if XC95xxXL is
selected, eg FPGA targets, Coolrunner/II - all report no issues with
the desgin, but as soon as it run with XC95xxXL selected then different
number of input pins are reported as not there. There is no clue why
they are disappearing and what else may be wrong.

Stepping back ISE history and installing 7.x then 6.x ...etc and
retesting in the hope that maybe
some older version works is really painful :(

I am using ise 8.1sp3 on an xc9572xl-10VQ64.

But I do rememeber I had to play a little with settings until the
project imported from 7.1 worked ok.

I am not sure, but may be it was Optimization Effort (turned to High)
the point I changed.

I suppose that it should work also with 8.2, but if you keep on having
problems, I may take a deepest look at the project under 7.1 and
compare it to the project under 8.1, to see the real changes I made.

I am installing 8.2 in a couple of weeks, I will the see if there
arise new problems.

Best regards,

Zara

Is this a design that did fit, and work, once on an (older) webpack, or 
is this a new design, that you hope will get better on an older system ?
Did you try the non-XL versions, (or have they now gone off the choices ? )

Jim,

its a new design. it seems to work as of reports for any other familes
except XC95xx (XL nonXL both fail). I am hoping to find some older
version that has functional XC95 fitter.
For what I see the 8.2SP3 just isnt doing much useful for XC95 family
and as that is the oldest device still supported I guess there is not
much hope the problems being ever fixed.

Hopefully I dont have to write my own fitter (I am capable of that).

Zara -

changin some options changed the count of pins that go lost 3 => 8,
(and yes only for XC95!) but its still not doing proper fit as much as
I understand.

got it working (or deliver reasonable reports at least) with ISE 8.1SP3

but only when synthesis goal is set to "area"

all attempts to play with settings in 8.2 have failed so far, eg the
input pins are missing no matter how much I have randomized the
synthesis/fit options.

maybe a perl script (similar to xplorer) that re-reruns the design with
different options and monitors when the missing pin appear again in
report and then stops?

Ok, 8.1 seems to work - so case closed this time.

Hi,
though not directly releated to the topic but i have similar problem
with webpack ise.
the follow code runs ok on 6.3i but fails on 8.2i. can anyone help me
out why its so and whats the solution?

addr_r       <= unsigned(addr_nxt(15 downto 1));
addr_r is declared unsigned(22 downto 0) while  addr_nxt is
std_logic_vector(15 downto 0)
i have also included libraries as :
 library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_arith.all;
use ieee.std_logic_unsigned.all;
use ieee.numeric_std.all;
with exactly the same files, this code compiles ok on ise 6.3i but
gives error on 8.2i, the error is that actual size is 23 while the
operand on right hand side has size 16.

thats correct (by ISE 8.2) it does more checks -
just add the (15 downto 0) to the lefthand operand
should work then

Antti

Thanks Antti, already thought so but i was not sure if thats the good
approach. i was puzzled because of the fact that it was working fine
with 6.3i. thanks for the help

VMware Server is gratis and once you've gotten your first Windows VM,
the next 1,000,000 are easy :-) VMware can use the host filesystem,
thus you can just set up a VM for each version of ISE etc. and try them
one by one.
