My question is: why do you want to put an FPGA architecture in your ASIC?

It definitely is possible (check out www.triscend.com for an
FPGA/microcontroller/memory in one device, or http://www.wsipsd.com/ for a
different integrated microcontroller device with a CPLD type architecture
included).

Actually, Siemens reports the capability to integrate Gatefield's FPGA
architecture in their ASICs, but I don't know of anyone who has experience
with this solution!

I don't understand what the big deal is here. If you are looking for small scale
configurability in an ASIC one can make a lookup table even using regular DFFs
and other standard cells. Or you can even design a new cell which has the
capability similar to a macro in any sram based FPGA and instantiate it in your
design. Of course this will be more time consuming and starts becoming full
custom but it is certainly doable. An ASIC process is a lot more flexible than
any FPGA.

I had the same problem on an NT box although mine would read from the CD,
oddly enough it works fine on other Win95/98/NT boxes in my lab.

I have not finished hacking away at it yet but I understand that the Dynatext
docs can be exported as SGML which can then be converted to HTML, there are
some pricey tools out there for doing this and also some freeware linux tools.

Dynatext is most certainly a pain, many times while documenting my designs
it would have been nice to link to certain pages but of course I cannot.

Considering that Xilinx uses a proprietary documentation viewer, they plan to
drop schematic support and the fact that they have killed two chips out from
under me after hyping them as their "latest and greatest" (5215, XC4000EX) I
am starting to believe that Xilinx has become the Microsoft of FPGA
companies.

It makes sense that you could do the below.  Have you done it?
Care to share any examples?  What about when you start
needing 16-bit Adders and Counters - does the LUTapproach get
cumbersome? I suppose it can work since that's all that a XILINX is,
but then, when I'm doing a XILINX, I have synthesis - if I do this
TODAY in my ASIC, I'll not have that luxury.  For more than just a few
logic equations and terms, it'd be *nice* to somehow use Synthesis
(it'd be neat if you could somehow make these macros into a Synopsys
library cell and actually synthesize to it!) and not have to
hand-craft every single configuration bit.  Lacking good "Place &
Route" tools, would it be better to have more complex, coarse macros
that would be potentially closer to a more human intuitive level?
Maybe the trick is; to pick an appropriate fine vs. coarse grain macro
based on your application and tools (or lack thereof).

but this beats the purpose, don't you think ? I think you are confusing the
initial synthesis where you define a cell and put it into your asic and the Field
Programming stage. If you know what features you want when you do the initial
asic, you don't need any FP cells. You are right that you need some kind of
synthesis and configuration tool to do the Field Programming part but I doubt
that will be Synopsys or any asic layout tool.

What I am thinking is minimal programmability from this new cell. So you can
define the FP Macro and program it by hand after you manufacture your asic. If
you want half standard cell/half FP cells on a 400K gate asic then you need a lot
more tool support for a much more complex FP macro and routing resources. At that
point you're reaching to the point of designing a new FPGA architecture yourself
and there are companies making a lot of money from that business already :-)

if you're desperate, you can use an XOR and a delay as a clock
doubler, so you won't need a PLL. see p9-7 of xilinx's 1994 databook. 

you could also look up the "How to Double Clk Freq in the FPGA design"
thread with dejanews (date 24/6/98), and check peter alfke's reply.

This question has come a few times on this group & one suggestion someone made
was to run some post P&R simulations and ``add up all the transitions''.   Is
there any simulator that can actually output the relevant data?  Effectiively a

For the later two questions and leaning way back to small C there is
one aspect fo the exercise you missed.  That it is an exercise.  He is
not selling the chip or the CPU design.  It's available, free, and
EDITABLE to something that may just be more useful for a given task.
For the author he has the leg up when applyig for a job as FPGA/ASIC
designer as he has tried something useless or not.

So back to your original question, why should you use it?  No reason
at all.  Take the time if you're interested to understand it.  Me, I
see it as a strange cpu with some interesting ideas but, then I cut my
teeth programming a PDP-8I.

At the other end of the spectrum I have a bunch of Xilinx parts and
doing my own cpu would be a fun exercise.  Would I do that one,
no.  There are features I'd want to look at.

I think I'm pretty clear about the 2 phases of the "synthesis".
Clearly, synthesizing the FP/macros themselves is the traditional
synthesis pass.  The second "synthesis", "place & route", whatever the
right phrase for this is, comes later, in the field, in the lab, via
programmable registers/SPI/shift-chains, etc., at run-time.  My
passing thought was just that if you could define a new set of
Synopsys library cells that were the macros, you could actually get
Synopsys to "synthesize" the configuration (you would still have to
then translate this netlist into the configuration data).  Just a
passing thought - I don't really expect this is easy or even doable.
We can drop the "synthesis" for FP configuration idea, and instead
try to come up with the FP Macros that are reasonable to configure
by hand...

I'm interested in devoting a very, very small percentage of my total
ASIC to this (1-4%).  For example, coming up with an IP (e.g. Internet
Protocol not the other IP!) packet filter on a downstream path that is
usable by the software people can be a challenging problem.  One can
come up with all kinds of ad-hoc circuits that, in the end, prove
inadequete.  A filter that's reconfigurable may have a better chance
of begin used.

What would the FP look like?  Like a XILINX CLB?  Coarser?  If you're
forced to program it by hand, and a little bit of silicon waste is
acceptable, would you include ALU type functions?  Hasn't anyone done
this before?

The only published benchmarks you are likely to see are
"advert-orials" presented by whichever company has marketing budget to
blow. Each will present some kind of *spin* on their results to show
how they were faster and *better* than anyone else.

Your best bet is to check that each tool in your price range produces
results appropriate to your expectations. Do P&R on the results, do
not believe any estimates from a synthesis tool. They may be
reasonably accurate, but some can be wildly optimistic, whereas some
can be pessimistic. The best range of estimates I have seen is one
tool saying 52ns, the other 17ns, and P&R being 49ns and 50ns critical
path respectively after P&R. Strangely enough, the 17ns tool was the
one to be purchased until somebody went through the 2 hour P&R run for
each netlist. After that it wasn't.

However, if you are going to benchmark, then you should ideally use a
number of designs that have more than just an adder or counter in
them, and decide what criteria you will use to evaluate the results.
Build a table of results and take the average of the post P&R results
for both area, final speed, and P&R time required. Try to keep the P&R
effort constant if you can.

Chances are, if you are looking at the two leading tools in the
marketplace, you will see an average of results that do not differ by
a great deal. This wil be especially true when using a "PHd" synthesis
methodology (That's Push *Here* dummy). If the vendor AEs are willing,
it may be a good idea to see if they can improve your results with any
tricks or other bells and whistles, as you would inevitably find those
and use them if you purchased the tool.

If each tool is still equal, or good enough for your purpose, at that
point then there are other things that may influence your decision.

Timing estimation accuracy
Constraint inputs and forward annotation etc.
Buffering of clocks and other signals (internal & external)
Scripting (if you like that sort of thing)
Hierarchy management/manipulation
Breadth of Language supported
Bells & whistles in terms of add-ons to the primary product
Technical support available from the vendor/distributor (Important)

It may also be a good idea to think about what you might need from a
synthesis tool vendor both now, and in the future (say 24 months).

If, after all that, you still can't make up your mind, then use a pin
on a piece of paper, or make an emotional decision about whether you
like/loathe the GUI or pretty CD case it came in. :-)

I think you can use any one of the OSS synthesis programs to generate output to
program your FP macros. Berkeley has nice tools.

If you have a well defined application, adding programmability or flexibility to
it is simpler. You can even create a semi-fixed state machine and let the user
decide on where and on what condition the transitions will be. A generic FP macro
might be an over kill for your specific app and it also might be too difficult to
use.

What I hope to be able to do is generate VGA color signals with a Xilinx
FPGA so that I can directly drive a VGA monitor. I also want to be able to
add an interface for a mouse so that the Xilinx chip can display the mouse
pointer on the monitor. I will probably need some D/A converters in order to
generate the analog signals for the VGA monitor, but I'm not quite sure
where to start.

One component for the ENV1 is the serial port.  I don't have
a FPGA descritpion of one, but I thought I would give a software
view of one, and high level code to view it.  Also, I will follow
this with hand compiled code for the TE16.

strong
technical contributors who expect outstanding performance from all of
their
colleagues.


PLEASE LIST ANY OTHER REQUIREMENTS THE SUCCESSFUL CANDIDATE MUST
POSSESS.

Advancement in the Bell Labs environment typically requires taking a

Subject: Why doesn't Xilinx's simulator work?
From: "Joel Kolstad" <JKolstad@Electroglas.Com>

Well, it's probably me... but damn it... I'm running Foundation 1.5 here,
and getting the schematic capture portion of the package to talk to the
simulator is nearly impossible.  I'll tell it to simulate a macro, it'll
open up the simulator, and then I'll start adding probe points.  The
simulator COMPLETELY IGNORES the probe points I'm clicking on, when it
should be adding them to its own list.  I'll click over on the simulator and
add some signals, and schematic captures completely ignores what's been
added!  Better still, sometimes schematic capture won't even let me add any
probe points at all, just completely ignoring mouse clicks!

You go ahead and step time in the simulator, and the signals listed do
reasonable things, but schematic just sits there with its probe points
displaying nothing at all.

!@$!@#%^^#$

OK, this doesn't happen 100% of the time.  On VERY RARE occasion it actually
works the way it should.  I can't believe this happens to all you other
people on a daily basis, or there'd be an angry mob outside of Xilinx HQ
threatening to burn the place down.  So what am I doing wrong?  The concept
seems really simple -- add a probe in schematic, and the simulator picks it
up, add a signal in simulator, and schematic should pick it up... right?

Subject: help xc3000 series
From: John Kennedy <johnkennedy@home.com>

I recently purchased a couple of tubes of XC3090 -125 and XC3020 -70
FPGAs $2ea at a electronics swap meet.  I realize that these parts have
been obsoleted by Xilinx.  But I wondering if they have any value as an
educational platform for students to learn about FPGAs?  I noticed that
Foundation 1.5 does not support the old XC3000 series.  Can these chips
be programed as the XC3000A?  Am I wasting my time and students time
with these obsolete parts?  Or, did I get a bargain that will allow
students to use an affordable (free) fpga in their projects?  Any
information / opinions would be greatly appreciated.

Subject: placement&routing problems
From: Utku Ozcan <ozcan@netas.com.tr>

Links: << >>  << T >>  << A >>
Design entry: Verilog-XL.
Synthesis: Synplify 5.0.7
Placement&Routing: Design Manager 1.5

We have just finished our last project. Our aim was to target
the chip to XC4062XL/-3, because the resource calculations seemed
to fit this device. Synplify gives ca. 600-650 CLB's for logic
and black-boxed internal RAM's consume less than 1200 CLB's.
We have to use some internal RAM to improve chip performance.

However, when we give the chip to Design Manager, it comes out
more than 1600 CLB's. The Map expands internal resources to ca.
2500-2600 CLB's, which exceeds XC4062XL. So, we have chosen
XC4085XLA/-1, which is pin-to-pin compatible to the smaller device.
So, it seems that the core consumes 80% of the XC4085XLA resources.

Firstly we meet x4kma errors, which solutions are suggested by
Xilinx folks. Two solutions are:

1. map -ir
2. INST XXX USE_RLOC = FALSE; (recently recommended)

We have used first solution till now, but we always had unrouted
which change from 2 till 2000. So, we have never come to end and
Design Manager always aborts. (We don't know how to use RLOC, so
would please give us some advice?

So, as it seems, we have a core half of which is internal RAM's.
As each P&R effort takes at least 2 days on Ultra-10 / 128 MB,
we don't have enough time to try perfectionist solutions.

Do unrouted regions have a great effect on these results? Does
the change of internal RAM organization (such as to organize it
with smaller RAM's generated by RAM compilers -LogiBLOX-) have
a real positive effect on resource sharing on FPGA?

Utku

PS:

Synplify:

Chip has 4 external clocks and 4 generated from one clock.
Internal clock generators have been implemented by counters.
We don't know how to assign those internal clocks to clock networks
on Xilinx XC4085XLA. Synplify warns that we don't use syn_clock.
But we haven't found syn_clock in Synplify Manuals. We have defined
external clocks and internal clock in *.sdc file but in speed grade
of -1 we have never met good delays. We have always got slacks. So
we have increased frequency rates of external clocks. Results fit
but there are slacks for higher frequences. We have tried constraint
commands on *.sdc file to improve the slacks but synthesizer has a
big "inertia", but unfortunately no improvements observed.

Design Manager:

We don't know how to define internal clocks in UCF file. We are
told to remove *.NCF, to have better results.

Any help will be greatly appreciated.
