Subject: Problems with high pin count FPGA systems
From: Arrigo Benedetti <arrigo@vision.caltech.edu>
Date: 14 Apr 1999 15:52:53 -0700
Links: << >>  << T >>  << A >>
The availability of very high pin count FPGA's (think at the Xilinx XCV1000
in the small pitch FG860 package, a device with 512 user I/Os) makes the
design of systems with very wide memory data buses very attractive
when you figure the bandwidth that you can achieve by dedicating the
majority of user I/Os to memory data lines. What I would like to understand
are the potential limitations of this approach from a system level perspective,
especially in terms of constraints given by routing congestions
of the memory controllers inside the FPGAs and signal integrity issues
like ground bounce noise generated by simultaneous switching outputs.

Has anyone ever had any experience with regard to these problems?

thanks in advance

The Philips coolpld family ( 3.0 - 3.6V - PZ3064 2kgates & PZ3032) may be an
alternate to the Xilinx 3030 Device. The spec sheet indicates a static IDDof
40ua for the PZ3064 device  with a 2MHZ IDD of 1.3ma. The PZ3032 2MHZ IDD is
specified at 200ua.

For low current battery powered FPGA applications
there are limited choices; Xilinx 3000L family  or Philips.

I couldn't tell from the article if this API makes it possible to
produce a synthesis tool for Virtex.  [Please, no flames or "why?"
questions].

I'd imagine not, going by the history of FPGA vendors.
But Xilinx did release the 6200 documentation.

Hi Craig:
I assume you left the AD data sheet on my desk. Do you know what form
the CIC filters take.
I.E. how many multiplies? Seems like we could outperform this chip by
10x based on the claim of 130 M FIR taps/sec. At 65 MSP/ we would have a
budget of 64 mults/sample.

Hi everyone,
     Has been dissapointing not to get any responses to my question. So I'll
pose it again. What is the best way to learn about fpga's, specially XILINX?
I want to be able to get my hands dirty with them, since I think they are
becoming an important trend in logic design. Schools don't do a good job, so
I want to know what's available ( student editions maybe?) for people like
me that want to learn about this subject. Thanks in advanced. Vic Lopez.

Yes, you can download it, but it won't work correctly. You will have to drop
back to XACT 6.0 I think. I had the same type of problem, in that I was
fielding some new bitsteam images for a board with 4000e and/or 4000 series
FPGAs. In order to satisfy all the fielded boards I had to use some old
synthesis and XACT6.0. For some reason the new XILINX tools will not support
the non E series 5v 4000s. You can compile the new image and load it, butr it
won't work. The older 4000 series had no clock enables, and different routing
features.

An Invitation to Contribute

Share your experiences ... The success of our users group depends on the
active participation of users who are willing to share their experiences
with others. If you have information on high-level design methodology or
experiences with Synopsys tools that would be of interest to other users,
you are encouraged to present in one of the sessions described below. 


Awards
  
First, Second and Third place awards will be given for "Best Paper".  The
winners are selected by the User Conference attendees.  


Preliminary User Breakout Sessions

These sessions are always the hit of the conference. Hear Synopsys users'
experiences on specific topics. Each user breakout session will consist of
three presentations, twenty-five minutes each, with another five minutes
for questions and answers.
   
               
Preliminary topics include: 

Synthesis/Design Productivity:

Strategies, experiences, and best practices for design productivity with an
emphasis on synthesis. Users share experiences with automation techniques
for synthesis. 

High-Level Verification/Simulation Techniques using Behavioral Coding:

The higher level a design is coded, the more complex the design becomes to
verify. This session calls for papers on behavioral system modeling
approaches when given design descriptions and performance goals. Further
discussion includes the verification/simulation strategies to ensure design
correctness.

FPGA & PLD Synthesis:

Having surveyed the User community, it was brought to our attention that
there is a desire to see more User papers on FPGA.  If you have any FPGA
stories to share with us, please come forward!  Concentrating on the unique
challenges of programmable logic, the tricks and techniques used for
designing and synthesizing FPGAs or PLDs will be presented. Incremental
synthesis, fanout control, and floorplanning issues relative to FPGAs will
also be part of this section.  

High-Level Verification/Simulation Techniques - (VCS):

System-level strategies covering design functional verification using
Verilog and VCS. Users share experiences in developing a test bed to verify
combined hardware and software systems for large complex designs. 

High-Level Verification/Simulation Techniques - (VSS):

System-level strategies covering design functional verification using VHDL
and VSS.  Users share experiences in developing a test bed to verify
combined hardware and software systems for large complex designs. 

Higher Levels of Abstraction/Behavioral Synthesis:

User experiences with using behavioral synthesis are explored in this
session. Topics include high-level design techniques, behavioral
scheduling, datapath synthesis, pipeline retiming, and integration with
other ASIC design and verification tools. Other topics include the
methodology for top-down design, and high-level techniques for DSP design. 

Hardware/Software Co-design:

Authors are invited to submit original papers describing recent experiences
in designing and verifying embedded processor-based ASIC/SOC systems. This
includes the methodologies used and tools required to handle tasks of
verifying both the hardware and software before physical prototypes are
available for these systems. Authors are encouraged to share their insights
on the use of the Eagle hardware/software tools, Cyclone, VSS, and VCS from
Synopsys and the overall impact on the project. Explore system design
objectives: Users experience with system development, verification and
integration. 

Deep Submicron/Large Designs/Power/Physical Design:

This session concentrates on the unique challenges of submicron and low
power design techniques that may involve large design, deep submicron and
physical aspects. Low power & physical design sessions provide experience
with automating scripts for submicron, special techniques for managing
wireloading, floorplanning, over consumption, and non-linear delay modeling. 

Makefiles Methodology/Configuration Management:

This popular session addresses the increased effort to automate and extend
the synthesis process through scripting. The session includes case studies
by users who have taken advantage of the power of Make and Perl to drive
synthesis iterations, to extend DC Shell, and to manage complex designs. 

Design Reuse:

This session includes a practical methodology for design reuse based on
real-world experiences. Issues and guidelines are explored. Does anybody
really have a working Design Reuse methodology in place? Let us know about
it and how it works. 

Test - DFT:

This session focuses on strategies and real-world experiences implementing a
manufacturing test strategy (DFT) for large SOC-type designs. Various SCAN
and isolation techniques are explored in the context of core-based designs.
Techniques used to interface a DFT solution (Full or Partial) with
synthesis and power will be included. 

Protocol Compiler:

User experiences with Protocol Compiler in system or ASIC design,
explaining what the advantages and disadvantages are of using Protocol
Compiler over conventional HDL methodologies. Users will discuss how
Protocol Compiler's high abstraction level eases the designing of
structured data streams. 

Module Compiler:

This session explores the use of Module Compiler to achieve high
performance datapath designs, focusing on effective datapath synthesis
strategies, coding styles, and integration with other ASIC design tools.
User experiences with datapath synthesis are shared. 

PrimeTime Techniques/Formal Verification:

This session explores strategies and user experiences using a static
verification flow, concentrating on highlights and lowlights of static
timing analysis using Primetime and Formal Verification using Formality.

Hi,
For one of my SOC designs, I need to take a make / buy decision for
JPEG(codec) synthesisable soft core(preferably in verilog). If any
one has any idea on any of the following then please respond.
1. The complexity in terms of gate count/ man month effort say for
a 50Mhz core.

2. Pricing info of any JPEG core available off the shelf in the
market.

An early response will be highly appreciated.

Thanks and regards

Did reducing the interconnects really reduce the price (of manufacturing) 
much? (I'm curious!)

Reducing the density of critical wiring can easily double or triple
the yield.  Since the wafercost stays the same, the cost per part
drops accordingly.  If you can get rid of one interconnect layer
(don't think that's the case here), you strip of some wafercost as
well.  The test and packaging cost is still the same, so even if you
get perfect yield at no wafercost the chips would still have to cost
something.

Subject: Some FPGA questions
From: ekuria01@kepler.poly.edu

Links: << >>  << T >>  << A >>


Hello, I am trying to synthesize a pretty simple interface board using Xilinx
xc4000 series and Fpga express. I am having some trouble.

1. When I go into FPGA express and load my code (a simple vhdl file with 1
entity and 1 behavioral arch), it compiles fine. I see that the icon that
represents my code has a green check on it. When i clik on this icon, i get a
yellow box with a pic of an or gate on it. Now, I click on FPGA express
"create implimentation". This gives me an error saying that my negative clock
edge triggered event will not work.

Error: This use of clock edge specification not supported
	in routine QSM1 line 129 in file 'C:/din/qsm1.vhd'  (HDL-109)

this is line 129
129:    if (ext_clk'event and ext_clk ='0') then -- and so on..

I know that teh xc4000 can do neg clock edges from looking at its CLB
architechture. Any ideas on why this is so ?  Thanks a lot for any help.

Brad,

I'm not sure what the context was here, but a CIC (Cascaded integrator comb)
filter is multiplier-less.  It consists of cascaded integrators (basically
an accumulator) and comb filters (an adder and delay element(s)).  There is
not a whole lot of flexibility in the response of these filters, but they
work well for high order decimation.  You might look up papers by Hogenaur
for more information.

Hello everybody.

    Does anyone out there have a couple of spare XC 6200 FPGAs or,
better indeed, any PC board with the XC 6200 FPGA on it?

    We are willing to buy them for a research prject.

    You can answer to fabregat@inf.uji.es

    Regards,
    Germán Fabregat.

The latest Tech Nore from VisiCom describes how an FPGA-based board can be
reconfigured to implement DSP function for image processing applications.

There are still 6200 Hotworks boards stocked at marshalls.
See our web site for details

	Remember that ~90% of the area of most FPGAs is in the
interconnect, and smaller designs generally have lower interconnect
requirements, so it makes sense to have the small parts use a less
rich interconnect, to save area.

	Also, when die size goes down, yeild goes up considerably,
which also reduces part cost.

Oooops! Big mistake here. I somehow sent this message to the news group
here instead of my co-worker. (I can't explain how, but I must have been
browsing the newsgroup when I started up the message). I guess it could
have been much worse. Does anyone know how to get a message off this
newsgroup?  This isn't the first time I've wanted to retract a post, but
this is the first time I've had an excuse.

I can't say much about what we are developing here, except that it's a
chip, it's not an FPGA and it's going to have good performance. 

Brad

I think Peter Athanas from Virginia Tech. has already written
a router based on JBits.  But the answer to your question is
Yes.  While JBits is is not a synthesis tool.
You write programs with JBits these programs can be used
to construct bit streams, modify bit streams (safest mode),
load bit streams (even over the net to remote nodes) and
read back bit streams (even over the net). Below is some
code snip to get a flavor of what JBits. It is a Java based
API for generation and manipulation of Xilinx 4000 based
(soon to be Virtex) bit streams (FPGA object code).



   System.out.println("Writing LUTs.");
   for (row=0; row<clbRows; row++)
      for (col=0; col<clbColumns; col++)

         try {

            /* Write F LUT */
            lut = Util.intToIntArray(row, 16);
            jBits.setF(row, col, lut);

            /* Write G LUT */
            lut = Util.intToIntArray(col, 16);
            jBits.setG(row, col, lut);

            /* Write H LUT */
            lut = Util.intToIntArray((row+col), 8);
            jBits.setH(row, col, lut);
            } catch (ConfigurationException ce) {
               System.out.println("Error writing LUT at CLB(" + row + "," + col + ").  Exiting.");
               System.exit(-1);
            }  /* end catch() */

   /* Write the bitstream */
   System.out.println("Writing bitstream.");
   try {
      bytes = jBits.write(outfileName);
      } catch (IOException  ioe) {
         System.out.println("Error writing file " + outfileName + ".  Exiting.");
         System.exit(-2);
      }  /* end catch() */

   System.out.println(bytes + " bytes written to " + outfileName + ".");



// Read you FPGA

   for (row=0; row<clbRows; row++)
      for (col=0; col<clbColumns; col++)

         try {

            System.out.print("CLB(" + row + "," + col + "):  ");

            /* Read Tag */
            tag = jBits.getTag(row, col);
            System.out.print("Tag: " + Tags.GetName(tag) + "   ");

            if (tag != Tags.PROTECTED) {

               /* Read F LUT */
               lut = jBits.getF(row, col);
               f = Util.intArrayToInt(lut);
               System.out.print("F: " + f + "   ");

               /* Read G LUT */
               lut = jBits.getG(row, col);
               g = Util.intArrayToInt(lut);
               System.out.print("G: " + g + "   ");

               /* Read H LUT */
               lut = jBits.getH(row, col);
               h = Util.intArrayToInt(lut);
               System.out.print("H: " + h + "   ");

               }
