Does anyone know if Xilinx PPR goes usefully faster on a Pentium Pro.
I have heard DOS software runs slower but given that its 32 bit 
software my hunch is taht it should go quicker.

Subject: JTAG config on ALTERA FLEX10K10: How?

Hello all.

There is no documentation in all the ALtera specs about
how to configure their FLEX10K devices via JTAG from an
embedded uC - all details are missing.

Does anyone use this option and can tell where the doc
is hidden or show the details ?

I'd expect something like loading a CONFIGURE instruction
to the IR then shifting the bitstream into DR similar to
the passive serial mode ?

Any hits welcome.
Thanks,
Andreas

Mmmh, 4000 pounds simulator with a 69 pounds synthesiser ;-) What I don't 
understand is why Cypress wrote such an impressive VHDL synthesiser and then 
complements it with a horrible editor and a near useless simulator. There are 
so many good shareware editors and simulators around which they could possible 
interface to with very little effort.

Subject: XILINX xchecker drivers on HP
From: Anders Kugler <kugler@gris.uni-tuebingen.de>
Date: Mon, 03 Mar 1997 15:26:15 +0000
Links: << >>  << T >>  << A >>
Hi,

We are using the XILINX XACT software on our HP 712 and 715 workstations
(HP UX 10.20) are having troubles with the system drivers to send data
over the RS-232 serial interface to the xchecker socket. We have already
sent emails to XILINX's technical support, CA, USA, with no 
satisfactory reply. 

Is there anyone who is using XACT and the xchecker on HP workstations
and knows where we could get the right device drivers?

XILINX doesn't and didn't provide us with any useful/successful 
information regarding this problem.
  
The following summarizes the problem we have:

1)------------------------------------------------------------------

We have bee trying  without any success to download a bitstream over
this cable 
by using the xchecker command and specifying the righ port 
name. We have also looked at your web page and searched for 
relevant informations regarding the configuration of the 
xchecker, for example the page content below, which does not 
apply to HP workstation configuration. The available ports to
the RS-232 are (obtained with ioscan): 

tty        0  2/0/4      asio0       CLAIMED     INTERFACE    Built-in
RS-232C
                        /dev/cul0p0     /dev/diag/mux0  /dev/mux0      
/dev/tty0p0   

/etc ll /dev/cul0p0     /dev/diag/mux0  /dev/mux0       /dev/tty0p0 
crw-rw-rw-   1 root     other      1 0x000001 Jan 14 10:06 /dev/cul0p0
crw-------   2 bin      bin        1 0x000080 Dec  6  1995
/dev/diag/mux0
crw-------   2 bin      bin        1 0x000080 Dec  6  1995 /dev/mux0
crw--w--w-   1 bin      bin        1 0x000000 Dec  6  1995 /dev/tty0p0

2)---------------------------------------------------------------

The device drivers didn't exist:

ls -l /dev/ttya /dev/ttyb

The result should be the following:

crw-rw-rw- 1 root12,0 month date time /dev/ttya
crw-rw-rw- 1 root12,1 month date time /dev/ttyb

so we created the nodes with ionode, with no success.

3)---------------------------------------------------------------

Creating softlinks doesn't help neither, as XILINX suggested 
(Xilinx technical support case #123599) :

        ln -s /dev/tty0p0 /dev/tty00
        ln -s /dev/tty1p0 /dev/tty01

with no success.

4)---------------------------------------------------------------
When using the xchecker program from the command line, and appending
options specifying to take an existing (on our workstations) device
driver, we get error messages from the xchecker program.

5)--------------------------------------------------------------- 
Any on-line documentation of XILINX doesn't help us any further,
i.e. we have read and already browsed through all on-line
documentation on that subject. 

In addition, the "hardware set-up" was checked several times, i.e.
external power supply for the xchecker and right connections between
the workstation, the cable and the XILINX FPGA on the PCB. We have
also tried different xchecker cables to eliminate the assumption
of a deffectuous cable. 
----------------------------------------------------------------

It seems to me that the necessary serial drivers are missing, 
in order to exchange data over the serial RS-232 interface to the
xchecker. What do we have to do install or configure those drivers 
properly?

Thanks and best regards, Anders

Subject: Re: Using internal clock of XC4000
From: fliptron@netcom.com (Philip Freidin)
Date: Mon, 3 Mar 1997 17:10:47 GMT
Links: << >>  << T >>  << A >>
If you just want to run the clock from the osc4 to a small amount of 
internal logic, just connect it up, no special buffers.

If you have lots of destinations, and want to use a global clock net, 
then you should connect the output of the osc4 to the input of a BUFGS 
(NOT a BUFGP), and the output of the BUFGS goes to the clock pins of all 
the FFs. This will use a global clock net.

If you are trying to get the clock out of the chip, then either connect 
directly to the osc4 or the BUFGS output to the input of an OBUF. The 
OBUF output goes off-chip.


Philip Freidin.

Can you elaborate on that bit about OLE, Robert?  Having done NO OLE
coding what do you reccomend for resources.  Does Viewlogic provide help
or hooks? Could you post an example script?

Does this realization mean that Xilinx will be releasing documentation on
the contents of its bit streams?  (Fears of reverse engineering being the
standard excuse, in the past, for not doing so.)

No, I'm not seriously expecting it, since it was always clear that this
was just an excuse, but it would be nice...

I was told last week that this still with Altera but is possible, just
ask them and they will work with you!

If you have any luck it would be good to know as we have yet to be
convinced that Altera are really on our (engineers) side, Fatcory
supported is the term they use I believe.

Have you looked at Application Note 59 - Configuring FLEX 10K devices ?

The datasheet mentions App note 39 - JTAG Boundary Scan testing in
Altera devices. I haven't seen that one but it sounds close.

AP NOte 39 covers all JTAG functions EXCEPT CONFIGURATION !
AP note 59 covers all config modes except via JTAG !
So these don't help at all.

I have the Altera CDROM and I looked at all docs related
to configuration or JTAG: there are no details about that topic.

Any more hints ?

AP NOte 39 covers all JTAG functions EXCEPT CONFIGURATION !
AP note 59 covers all config modes except via JTAG !
So these don't help at all.

I have the Altera CDROM and I looked at all docs related
to configuration or JTAG: there are no details about that topic.

Any more hints ?

True - we have been having great success with the non ISR version of the
374 part. But! :) I want to be able to include SRAM's in the design
ala Xilinx (synchronous dual-ported SRAMs).  For pedagogical reasons :)

Also, the PLD/CPLD architecture is not that efficient for more complex
designs. And simply not big enough!

: Mmmh, 4000 pounds simulator with a 69 pounds synthesiser ;-) What I don't 
: understand is why Cypress wrote such an impressive VHDL synthesiser and then

Nova is a jedec simulator and is included for historical reasons - and
is more than sufficient for anything one could imagine doing in a
16V8, 20V8, or 20V10. In fact to test a 16v8 it is very quick. For simple
designs a waveform editor has a lot of advantages over a 4000 pound
gorilla of a simulator.

Warp 4.1 supports a range of simulators for post synthesis simulation, both
VHDL and Verilog. I think the notion here is point tools. The FPD vendor
supplies the synthesis tools. The customer uses a general purpose simulator.
For both pre and post synthesis simulation - and of course Warp includes
static timing tools for FPGAs.

I think the assumption that a user of Warp2 will have already invested in
a HDL simulator is a reasonable one. And expected. Supplying tools
that can work together is the whole notion behind CFI's goal of having
open EDA tools, and standard languages such as VHDL and Verilog.

If you look at say the Xilinx Foundation series they are very close to the
same model as Warp2. And I think also Synopsys FPGA Express. It is not clear
to me from the web ads if and what sort of simulator they each include
or support.

As to an editor, it clearly has some problems. I suggest using lemmy
the windows 95/NT vi clone :) I take that back! Please don't start a
"my editor iis better than your editor" wars. I mean the GNU emacs
port to NT!

Warp2 has really matured and does what it advertizes very well - so
well in fact undergraduates can successfully use it independently
to produce first time working designs for their senior design projects...
that fill a 374

Now if I could just figure out how to feed the VHDL output of
the Synopsys behavioral compiler into Warp2....

Steve,
AP NOte 39 covers all JTAG functions EXCEPT CONFIGURATION !
AP note 59 covers all config modes except via JTAG !
So these don't help at all.

I own the Altera CDROM and I looked at all docs related
to configuration or JTAG: no details about that topic.

There are exactly two statements in all the docs:
  1) JTAG configuration of FLEX10K is possible
  2) You must use the ALTERA bitblaster to use
-> Very useless information



Any more hints ?

Unfortunately this tech note doesn't quite answer the question Chris
asked, especially the 'usefully' part. Does anyone have any idea of the
kind of performance improvement, specifically run time for PPR, you get
from changing to a 200 MHz P6 from a 166 MHz P5, as a ballpark
percentage? This information would help us determine if it is worthwhile
upgrading our PCs at this time.
		ta very much, Syms.

Just a factoid:

I once tested a Pentium-100 against a PPRO-200.

The design was a 4010 with abt. 92% of the FlipFlops used and no
completely free CLBs. There were _lots_ of synthesized XBLOX
devices; the rest was schematics.

Compilation time fell from 48 to 13 minutes for netlist generation
to loadable bit file. I tried this only once (why wait?) and did not
enforce equal seed numbers for the placer. 

The machines both had 32M of ram; the P100 had everything on its
local SCSI disks; the PPRO200 accessed the XILINX software via
Novell Netware + Ethernet. Disks probably play no role in this
cpu bound application. Software was Xact 6.01 under DOS without
Windows.

Your mileage may vary.
