Yes, even a -4 can be used with some restrictions.  If you are
referring to the Xilinx VHDL model be aware that they have not ( as of
a seminar in late november) built the thing just simulated it.
 
Be sure you have a copy of the formal PCI speck, it is actually readable!.
 
PCI tip: The card is reverse of standard PC (isa) card, be carefull
reviwingPCB layout, our first board cam back with the fingers on
the wrong side ( A X B ). Did notice before we plugged in, would

Contact EIA, The Electronic Industries Association, for a copy of the
standard.  They've just recently moved and I don't have the new
address.  LPM is a standard within the EDIF realm.

I would like to know if you can use the Orcad output from Protel for Windows
to feed the Xilinx software.  A friend who called Xilinx was told that only
Orcad STB-386+ (or something like that) would work properly and that other
versions of the Orcad software don't work.  This led me to question whether
or not the Protel for Windows Orcad output would work.  Since I already own
Protel, I didn't want to have to buy Orcad and learn yet another user interface.

	Thanks,

It probably will not work. The Xililinx tools use the raw ( .inf?)
net info from Orcad. This is an intermediate netlits that Orcad then
reformats into variouse forms. Unles Protel has the same intermediate

that wold be a Protel tool and would use the Xilinx Orcad tools only for

No reason it wont work, the file is read from the disk, no storage in
the cable.  A quick testif you have a board with one  4010 on it woul be
to gen up a ROM image with 5 copies of the config file for the 4010
an try loading that. If that loads almost for sure the string of 5 will
work. ( May complain about done bit early, point is to see if it
can read the file )

Yes this works. The XC4000 must be the lead device, and the XC3000 part
should be in serial daisy chain mode. The differences in framing codes
does not effect the lead device (the XC4000), as it only looks at the
bits at the beginning that are for it. When it is full, it starts passing
the following bits (for the XC3000) from din to dout, and does not look
at the bits. After the XC4000 is is full, and passing data to down-stream
chips, the only thing it is still doing is counting bits waiting to
go done. There should be only 1 header in the file, with the lengthcount
field set to the sum of the two bitstream lengths.  The makeprom program
can do this for you. 

All the best

Martin,
	I'm not sure I understand your last statement about "that would
be a Protel tool".  I just heard from Tech support at Protel that the new
version of the schematic package has a .XNF output.  How would the process
work then?  I'm assuming that I would create a schematic in Protel, output
a netlist in .XNF format, and then feed that to the Xilinx software for
routing, etc to create the image file for the EPROM.  Is this correct?  Would
I be able to use the stand parts library in Protel as long as there were
matching parts in the Xilinx library?

According to the news wires, fourth quarter earnings will be less than 
expected, but not by much.  Also a lawsuit by stockholders has been filed 
with a complaint that insiders have been selling large amounts of stock 
recently before the drop.  In my opinion, Viewlogic was over bought, and 
selling at a big premium, but now at 9 1/2, it may be a good buy.  Fourth 
quarter earnings will be released the third week of January.

No, you'd want to convert the old Xilinx OrCad libraries into Protel
libraries, and then use *them*.  Also, some of the macrocell functions, in
fact anything other than the basic elements reference the converted
schematics (*.PIN, usually, *.SCH and/or *.SP3 for the source), and may not
link in properly to the Protel .XNF file; you're in for a fun time!

 The plunge in Viewlogic was due to the usual, earnings were less than
 projected.  Wall Street doesn't like surprises.  Viewlogic attributed the
 change due to the fact that sales of HDL products are doing better than
 expected, at the expense of their schematic-based products.  This product
 change over is effecting their cash flow more than they thought.  Also
 they could not sustain their rapid growth forever. WSJ  also has an
 article in the January 4 edition.

If Protel has .xnf output there is a good chance that they also
have the libraire converted. Xnf without the libraries and macros would not
meanmuch and if they are Orcad comaptible it would not eb hard for them to do.
 
If they do have the libaries and .xnf you would simply feed the .xnf into the
Xilixn tool chain as usual.  The .pin is now the .inf format, .pin was
the earlier Xilinx version that used Dataio net list format. The point is
still valid though unless Protel has (or can directly use) the Xilinx
library the effort would not be trivial.

I am not aware of any low cost software for FPGAs, Xilinx offers a basic
package for under $1000, but it is only good for the smaller devices, and is
not full featured.  I think you have to provide the schematic capture software
for that as well.  I wholeheartedly agree that it is not cost effective to buy 
the software to do one or two chips. There is another alternative you may not 
have considered.  I run a consulting firm specializing in high performance FPGA
design.  One of the things we do is to convert existing designs into FPGA 
designs.  The advantage of using a firm such as mine for someone like you is 
that we've already invested in the tools and have gained substantial experience
using the tools and designing in the parts.  My firm uses Viewlogic's Workview
Plus along with the specific tools from each of the FPGA vendors.  We provide 
complete design, simulation and integration services for a very reasonable fee.

    ------------------------------------------------------------------------

The Third Canadian Workshop on Field-ProgrammableDevices: Technology, Tools and
Applications May 29-June 1, 1995, Montreal, Quebec

ADVANCE NOTICE AND CALL FOR PARTICIPATION

    ------------------------------------------------------------------------

The Ecole Polytechnique de Montreal and the Universite du Quebec a Montreal
will host the Third Canadian Workshop on Field-Programmable Devices (FPD'95).
The goal of this Workshop is to bring together workers from throughout Canada
for a wide-ranging discussion on all forms of field-programmable devices and
their applications. Discussion will focus on industrial applications, advanced
CAD tools and systems, novel system architectures and educational experience.
English will be used for discussions and the principal printed materials, but
contributions can be submitted and presented in either English or French.

SPECIFIC OBJECTIVES AND SCOPE OF THE WORKSHOP

    ------------------------------------------------------------------------


     To continue to provide a forum for discussion on the design and
     application of FPGAs

      To provide an appropriate forum, both for those in industry and those in
     post-secondary education

     To allow manufacturers of field-programmable device software and hardware
     an opportunity to present their products to a specialized group

     To include a wide range of field-programmable devices such as interconnect
     components, analog arrays, etc.

     To increase the emphasis on designing at the system level, using synthesis
     to generate the circuit details

These objectives will be implemented through: -

    ------------------------------------------------------------------------


     Hands-on training -

     Tutorials and demonstrations -

      Industrial and academic case studies -

      Industry, university and educational paper sessions (lecture and/or
     poster formats) -

     A session on commercial opportunities and business implications

SUBMISSION OF PAPERS

    ------------------------------------------------------------------------

Prospective participants are invited to submit one (1) copy of an extended
summary to the Organizing Committee Chairs for review. The summary should be no

active forum for the exchange of ideas for course and laboratory development.
Industrial users are also encouraged to present case studies utilizing
field-programmable devices in their particular environment. Papers describing
how practical problems have been overcome are welcome. Manufacturers of
field-programmable device software and hardware may also make presentations on
the engineering characteristics of their software and/or devices. We are also
soliciting presentations on the commercial and business aspects of this
technology, including entrepreneurial issues. Examples of topics are: financial
considerations of introducing field-programmable devices into the product life
cycle; when to switch from field-programmable to mask-programmable gate arrays;
etc. A combination of both lecture-style presentations and poster/demonstration
sessions are planned for the workshop. The poster/demonstration sessions are
provided for those applications where it makes more sense to present results
using this format. Ecole Polytechnique may be able (reservation required) to
lend workstations, PCs and other large equipment for use in demonstrations.
Vendors of field-programmable-related products will also have a forum for
demonstrating and promoting their products among workshop attendees.

HANDS-ON SESSIONS

    ------------------------------------------------------------------------

During this Workshop, we anticipate hosting several hands-on sessions for a
wide variety of users from novice to expert. Plans are being made to include
tutorial sessions given by the major tool and device vendors.

organized for non-participants.

OTHER USEFUL INFORMATION GENERAL:

    ------------------------------------------------------------------------

Montreal, a fusion of European style and the American way of life, is one of
the loveliest cities in North America and is situated between the St-Lawrence
River and Mount Royal. After Paris, Montreal is the second-largest
French-speaking city in the world, with the advantage of offering services in
English as well. TRANSPORTATION: Both airports offer convenient public
transportation into downtown Montreal. The one-way shuttle bus fare is $8.50
Cdn. from Dorval and $13.50 from Mirabel. By taxi, the trip into town is about
$25 from Dorval and $60 from Mirabel. In Montreal, there is an extensive bus
and subway network (Montrealers call the subway the "Metro"), and a ticket for
either costs $1.75. WEATHER: During the month of May, temperatures can vary
quite a bit. During the day, they may reach 22 C, or drop to as low as 8 C.
Evenings are generally cool (4 to 10 C).

Hi Dave,

If you have one of the old parallel port download cables, then that
definitly has no limit.  The file simply seams to get read from disk
as the bits are spat out the parallel port, one bit at a time.  The
only problem with that is that as the Xilinx devices have got faster,
they have become more sensitive to glitches (and hence ringing)
during download.  The only big benifit with the XCHECKER is that the
leads are short and ringing is not a problem.  I like the old
DOWNLOAD cable but after a lot of heartache & study, I have deciced
that the only correct solution to the ringing problem is by adding an
active buffer (74HC14) at the Xilinx end of the cable.  Some old
Xilinx manuals gave the schematic of the parallel download cable, so
you could make one if you havn't got one handy (but watch out for
ringing).

I am asuming that you are not running long leads from the body of the
xchecker head.


Regards

Michael.


Article: 572
Subject: RFD: comp.cad.viewlogic
From: scott@gordian.com (Scott Murphy)
Date: 8 Jan 1995 18:54:48 -0500
Links: << >>  << T >>  << A >>
Request for Discussion (RFD)

Newsgroup       : comp.cad.viewlogic
Status          : unmoderated
Distribution    : Worldwide
Summary         : For discussion of Viewlogic's CAD software
Proponent       : Scott Murphy (scott@gordian.com)


This is a formal Request For Discussion on the creation of an unmoderated
newsgroup, comp.cad.viewlogic.

This RFD has been posted in accordance with the Guidelines for Newsgroup
Creation.  Its language is based on previously submitted RFDs.  The RFD is
being cross-posted to the following relevant news groups:

        news.announce.newgroups
	comp.cad.synthesis
	comp.arch
	comp.arch.fpga
	comp.lang.verilog
	comp.lang.vhdl
	sci.electronics.cad


CHARTER

The comp.cad.viewlogic newsgroup will be open to discussion of the use of
and any problems or conditions arising from the use of Viewlogic's Powerview
and Pro series CAD software.  Specific topics may include but are not limited 
to:
	Installation		Design methodology
	Security		Verification and Validation
	Bugs			Vhdl
	Customization		Product enhancement

This group is not affiliated with Viewlogic, but it is hoped, that employees 
of Viewlogic will participate in the discussions.


RATIONALE

As Viewlogic has grown, it's software has evolved from a simple pc based 
schematic capture system into a full electronic design package.  This growth
has increased the difficulty in effectively using and maintaining that 
software.  This forum will provide users of Viewlogic's software a place to 
solve problems and share ideas.  It is hoped, that Viewlogic will use this
group to aid their customers, and to solicite information about those customers
needs.


MAILING LISTS

No know lists exist.


FUTURE CALL FOR VOTES

After a discussion period of 21-30 days, if there are no overwhelming
objections to the proposed group, there will be a Call For Votes (CFV)
posted to the same groups as this RFD.  The voting period will be at least
21 days.  If the group passes by receiving 100 more YES votes than NO
votes, and (at least) twice as many YES votes as NO votes, it will be
created.
