I still think that (if you're doing straight ECB or CBC encryption or
decryption) a slave DES processor such as the 95C68/18/09 or 20C03
will be cheaper and just as fast.  Check out Newbridge/Tundra.

(Of course, a DES cracking application may need a few unconventional
hooks...)

Subject: Synopsys Timing Analysis on Altera (flex10K) back-annotated design
From: alexk@dspis.co.il (Alex Koegel)
Date: 4 Sep 1996 10:20:55 GMT
Links: << >>  << T >>  << A >>
Hello FPGA'ers,

I am having an increasing need to DC time analyze (with Synopsys DC timing 
analyzer) back-annotated designs from Altera.

More in detail:
After exporting the *.edf (Synopsys FPGA-Compiler generated) to MaxPlusII (Rev 
6.2), and compiling it with 'Verilog netlist writer - with SDF output' option 
turned on, I am trying to perform a Synopsys DC Timing Analysis on the 
Altera generated  *.vo VERILOG files - to no avail. 

Synopsys is unable to read in the Altera GENERATED *.vo Verilog files (it 
failed on non-synthesizable code). The next step - 'read_timing *.sdf' - is 
of-course irrelevant - since the first step failed.

Is there an available methodology today where I can generate a netlist from 
Altera, with back-annotated timing, such that Synopsys can read & perform 
critical paths DC Timing Analysis ?
 
(I have tried the combination of *.edo (Altera EDIF Out) netlist with *.sdf - 
to no avail).

Well, 

I'm using XACT6.0 and this won't work either with WIN95.
The reason is simple : the software needs win32s.

So I installed win3.11 and win95 on the same computer, and everything runs
fine now.

There's a bunch of work on translating software languages (especially C)
to hardware.  Below are my notes on many of them, which are going into a
survey of software for reconfigurable systems that I'm working on.  I'll
have a less terse version in a week or so.  If anyone knows of any others,
I'd appreciate pointers to them.

Transmogrifier C [Galloway95] - no multiply, divide, pointers, arrays,
structures, recursion.  Adds pragmas to declare width of variables, and
methods for declaring inputs & outputs (w/pin assignments).  If statements
becomes equations (condition & assignment combined).  Control flow becomes
control FSMs, with states for each loop, function call, etc.  One thread
of control per program, but multiple programs can be combined.

Spyder [Iseli95] - no multiply or divide, only bitvector variables.  Very
restricted language.  Intended to design operators to be put into FPGA
hardware.  Then, code is written to run on the processor & use these new
execution units.

PRISC [Razdan94b] - Automatically goes from assembly to FPGA (won¹t do
memory ops, floating point, wide adds, multiplies, divides, variable
shifts).  Selects which portion is mapped to FPGA logic, though seems
somewhat rudimentary.

PRISM [Athanas93] - User picks which subroutines to convert to hardware. 
Converts C to hardware.  No global variables or state, restricted
bandwidth, fixed iteration count for loops, no floating point, no case or
do-while.

PRISM-II [Wazlowski93, Agarwal94] - extends PRISM to include
variable-length loops, whiles, switch.  Still no structs, floats, or
pointers.  Direct conversion from C to VHDL or X-BLOX.  Then optimizes
control-flow to speed up control FSM.

[Wo94] - RECON¹s compiler.  Can¹t handle multiply, division, modulous,
function calls.  Straightforward C to FPGA.  User decides what to map
based on profiling, only a complete function can be mapped.

[Clark96] - Standard retargettable compiler for DISC.  Allows one to
include calls to hardware subroutines into the code (though interface code
must be hand-made).

Basically floating-point is one of the big issues with FPGA-based
systems.  By and large, people don't do it.  As you can see from the above
list, it just isn't supported.  Primarily I beleive the reason is the high
hardware costs (you could hit dejaNews about 6 months ago for a discussion
in this group on floating point in FPGAs).

So, if you want someone else's work to use, I don't think it's out there. 
If you want an interesting research project, this could be it (however, my
take on floating point is that it should be left in a
processor/DSP/coprocessor instead of trying to shoehorn it into an FPGA).

If you're going to do work on this, make sure to take a look at the DSP
community.  I think they've had to do a lot of this kind of stuff for
fixed-point DSPs, though I'm not an expert on this area.

Good luck, and let me know how things turn out.

The generic toolkit of choice, IMHO is the Galileo toolkit from
Exemplar Logic (now a part of Antares, www.antaresco.com).  It will
allow you to target most all FPGAs, many CPLDs, and also ASICs.  I
believe that the PC price tag is not bad, but I don't know what your
budget is.

Have you tried to an incremental place and route?  This uses that
previous place and route information, and only rips up what it has to.
It usually speeds up the process quite a bit.

Only two Cadence employees and one Avant! employee responded (which didn't
change the EDA vendor stats significantly.)

Concerning your sample size is too small & self selection reasoning, from
my sometimes questionable memory of a statistics course a zillion years
ago as a sophmore engineering student, I remember that these two arguements
aren't factors here.  That is, the 36 EDA Vendors and 311 EDA Users both
used the *same* selection process, so comparisions *can* be made between
the two populations.  In addition, there obviously is some sort of real
difference in the way the two groups see the world on *this* issue
because of the strong similarities between these two populations (both
are computer literate engineers who know something about electronic
design software.)  The only distinction is that one group buys EDA
software while another group makes EDA software.  Not that much of a 
disjoint difference.   It's not like comparing EDA users to, say... 
left-handed, Laplander lesbians.

Subject: synopsys vs. xilinx floor-planning
From: lbutcher@Eng.Sun.COM (Lawrence Butcher)
Date: 5 Sep 1996 00:19:22 GMT
Links: << >>  << T >>  << A >>
I am running a verilog design through synopsys fpga-compiler, and then into
the xilinx place and route software.

I really want to place things in this design for speed.  I can get at least
a factor of 2 in speed by careful placement of certain modules.

The way things seem to go, every time I run synopsys I have large parts of
the placed design become unplaced due to gate names begin changed.  Some flop
names change too, but these are usually associated with mis-synthesized clocked
bidirectional IO pads, and you give up and manyally instantiate those.

I try labeling begin-end blocks, and that doesn't help.  Module names staying
the same doesn't seem to be enough.  I try to generate combinational logic
manually inside always @(a or b or c) out = a ^ b ^ c; blocks, so that important
gates have names that stay constant across synthesis runs.  I seem to end up with
"U5932" and "N5678", which are trouble.

Lots of flops DO stay put.  But about 90% of the design is in parts of the
design hierarchy called "Primitives" and my favorite "U".  These are doomed.

I want my placed gates to stay put.  If I were to call Xilinx or synopsys, my
guess is that they would say "you are the first person to ever ask for that".

I wouldn't mind being able to put pragmas in the verilog to do source level
relative placement of modules, and bounding boxes on them too.

So to you experienced designers, the hundreds of other people who have also
been the first one to think of this, are there any tricks that I am missing?

Altera is a very large corporation with hundreds if not thousands of phone 
and fax numbers as well multiple addresses for differnet buidlings.  What 
do you want to ask about?  If we knew that, perhaps we could help.

Hi everybody,

I have a description of a simple, generic ripple-carry adder circuit in our
own Lola HDL, but I would like to translate that description to the more
popular languages VHDL and Verilog. Can anyone give me a hand?

Thanks,

Lola HDL for the definition and use of a generic ripple-carry adder:

MODULE Add;

    IN x, y, ci: BIT;  (* inputs: 2 data, carry *)
    OUT s, co: BIT;  (* outputs: sum, carry *)
    VAR h: BIT;  (* half sum *)
  BEGIN
    h := x-y; s := h-ci;  (* two XORs *)
    co := x*y + h*ci  (* two ANDs and one OR *)
  END AddElem;
  
  TYPE Adder(N);  (* generic N-bit full adder *)
    IN x, y: [N] BIT; ci: BIT;  (* inputs: 2 data vectors + carry *)
    OUT s: [N] BIT; co: BIT;  (* outputs: sum vector + carry *)
    VAR add: [N] AddElem;  (* using N full adders *)
  BEGIN
    add.0(x.0, y.0, ci);  (* unit assignment: add two bits *)
    (* then ripple-carry *)
    FOR i := 1 .. N-1 DO add.i(x.i, y.i, add[i-1].co) END;
    FOR i := 0 .. N-1 DO s.i := add.i.s END;
    co := add[N-1].co
  END Adder;
  
  CONST N := 8;
  IN x, y: [N] BIT; rd: BIT;
  INOUT D: [N] TS;
  VAR adder: Adder(N);  (* instantiation of generic *)
BEGIN
  adder(x, y, '0);  (* unit assignment (with vectors *)
                    (* x and y and the constant zero) *)
  FOR i := 0 .. N-1 DO
    D.i := rd | adder.s.i  (* rd controlled tri-state assignment *)

Links: << >>  << T >>  << A >>

Hi!

I am looking for a PCI compliant FPGA which has at least 5k Gates. Moreover
it must be more than one time programmable and the place & route software
should be free or very cheap (since I am a student and need it for my private
purposes). As I found out, Motorola offers a free version of their software,
but unfortunately their devices aren't PCI compliant.
Thank you very much in advance.

Sounds pretty damn fast to me :-)

Whether it is or not depends on (a) device type/size (b) % utilisation 
and (c) effort settings used for P&R.....

I think what your problem is major. In any case, the problem will occur.
 ex. Your computer have over 32MB RAM and your computer's VGA chip is S3.

Please try what connect to Xilinx BBS or Xilinx FTP Server, and download
the '/pub/swhlp/aldec/w32s13c.zip' file and install it.

Subject: Warp2 realease 4.0 ??
From: wolf@step.polymtl.ca (Patrick Jarry)
Date: 5 Sep 1996 22:53:51 GMT
Links: << >>  << T >>  << A >>
Hi everyone,

In many engineering and design publication, I've heard of Warp2, which is
a VHDL behavioral synthesis for Cypress programmable logic.  They claim
that their software offers better synthesis than 20 000.00$ packages, with
IEEE standards synthesis, simulation output, auto fitting and
plac-and-route, etc. all this for 99.00$. 

Being a student, I can't afford very expensive FPGA's or PLD's 
development system, but I'd like to know if anyone of you tried this 
software, and what was the performance like. Because even at 99.00$ I 
want to make sure that it's worth the money.

Thanks a lot,

Patrick Jarry,
computer and electronics engineering student
