You can use a "sentinel" bit (perhaps a 1) that gets loaded into an extra bit at the end of the shift register during the parallel load. The serial input of the shift register is set to the opposite state (0). When the sentinel is shifted out (after the data bits) the shift register will be all 0. You can detect this (or more usefully, the state before it), and trigger a new parallel load. This is a common programming technique. Allan.Article: 22026
Hello, I'm student from Spain and I must configure a FPGA 4085XLA from Xilinx with the XCHECKER. I read in the Xilinx web that a 3V adapter is needed to do it, because the XCHECKER works at 5V. What is it? Is there a schematic to do it? Does anyone help me? Thanks.Article: 22027

I didn't take a long look at your code or your waveform, but one problem
jumps out immediately in your code. You have three always blocks that have
interdependencies and blocking assignments within these blocks. The
execution order of the always blocks is not deterministic in verilog. Use
just one always block and put your three cases inside of the one always
block. Verilog uses blocking vs. non-blocking assignments ( = vs. <=).
When inside a synchronous block, you should be using non-blocking
assignments (that way it looks like a flip-flop - data doesn't change
exactly on the clock edge, but after everything has settled - it is
generally a good idea to do your flip-flop assignments like this
always @ (posedge clk or posedge reset) begin
if (reset) ....
else begin
a <= #1 b;
end
end
The intra-assignment delay will be ignored by synthesis, but will insure
that the assignment doesn't have any chance of "feeding through" (the
non-blocking operator does this as well, but sometimes you can run into
issues with interdependencies with multiple clocks). Another advantage is
that you see the data change after the clock edge in your waveform. This
delay won't have any adverse effect on your RTL simulations and won't exist
in any gate-level simulations - so it has no negatives and has positives.
That seems like a good idea.
As for your waveform viewing, you are seeing the data at then end of the
time-unit, but you don't have the order information on when the transitions
occured.
For instance, if DataIN and test and TargetWRCtrl are all changing (as in
your code), there is no determinism in the order they change (according to
the Verilog language - and believe me, different simulators do it
differently). So, It could be that your TargetWRCtrl get's changed first,
then DataIN, then test. However, it could also be that test get's set before
DataIN.
Now, if you were using non-blocking assignments (<=) - this would all
resolve itself as the assignements wouldn't actually be done until all of
the blocks in a given dependency list have been processed.
Here is one more way to look at it in Verilog.
always @ (posedge clock) begin
a <= b;
b <= a;
end
This case has a and b as two flip-flops whose inputs feed each other
(neigher a or b are changed until all events in the current time-unit event
queue are resolved.
always @ (posdege clock) begin
a= b;
b = a;
end
This case has 2 flip-flops - with a being set to b and b feeding back on
itself (as the value of a has changed before the assignment of b).
always @ (posedge clock) begin
a <= b;
always @( posedge clock) begin
b <= a;
Same as case 1 - we don't know which will be evaluated first, but it doesn't
matter as the non-blocking assignments mean that we won't assign the values
until the event queue processing has completed
always @ (posedge clock) begin
a = b;
always @( posedge clock) begin
b = a;
Completely non-deterministic.
Don't know if a get's assigned first or if b does.
Check out a good Verilog book - like Palnitkar's Verilog HDL. As for the
event queue, there is a very good description in Thomas and Moorby's ' The
Verilog Hardware Description Language'

Article: 22031The Xchecker cable drawing on page http://www.xilinx.com/support/programr/cables.htm also has a little drawing of the HW-XCH3V adapter. Looks like it contains a couple of 5V-3V buffer packages and a simple DC-DC converter to convert the 3.3V device VCC to 5V for the Xchecker. Avnet lists it (in stock) at $104.50 (http://www.avnetmarshall.com). I recall that the XLA has 5V tolerant inputs. Maybe all you need is a separate 5V supply for the Xchecker cable, and a couple of transistors or a relay to gate the 5V so that the Xchecker is never powered up (and driving device inputs) when the device VCC is off. Note: You might want to get a second opinion before you go off and start frying 4085XLA parts :) It might be simpler to just buy the adapter. regards, tom Ricardo Matias Moreno Moll wrote: > > Hello, > I'm student from Spain and I must configure a FPGA 4085XLA from Xilinx with > the XCHECKER.

Hello I am looking for PCMCIA IP. I am doing a design using PLDs and I would prefer to avoid having to develop PCMCIA Cores myself. I was wondering if anyone can direct me to a website or company who can provide HDL PCMCIA cores or something similar. Thank you AlexArticle: 22034
Hello I am working with PLDs at the moments. I need a PCMCIA core or IP I can add to my design. I have had a look around for IP, but I have not had much luck. I am working with two teams, one using VHDL, the other Verilog. Since like most PLD and FPGA users we want fast time to market, I was wondering if anyone can recommend PCMCIA cores (of any sort) or companies who can provide them. I am working with Altera technology at the moment, but I am curious about what other companies have to offer.

Thank you very much to Tom Burguess, you were in the right direction. In Xilinx web I found (http://support.xilinx.com/techdocs/5501.htm) this: "The power that you provide to an xchecker and JTAG cable is what the control signals will be at. If you provide 5 volts to a cable and you are programming a 3.3 volt part, you will be driving it with 5 volt control signals which is ok in 5 volt tolerant devices. The XChecker cable needs to be powered at 3.6 volts or higher. The JTAG cable can run at 3.3 volts and up." I'm doing a PCB with both 3.3V and 5V, so I don't have any trouble.

Good point - This would be the "5V tolerant I/O" checkbox in the configuration options dialog. When checked, this presumably prevents the VCC I/O clamping diodes (needed for 3.3V PCI compliance) from being enabled after configuration. Since the data sheet does not say that the config and JTAG pins do or do not have these diodes, one must assume the worst. regards, tom Andy Peters wrote: > > Tom Burgess wrote in message <38F6B817.5600785C@home.com>... > > > >I recall that the XLA has 5V tolerant inputs. > > Only if you set the magic bit during configuration. > -- Tom Burgess Digital Engineer Dominion Radio Astrophysical Observatory P.O.

Hey all. I have a few questions on on the VHDL/FPGA software that is available. I've heard of several packages like ModelSim, FPGA Express, Leonardo Spectrum, VeriBest, etc. What I want to know is to these tools produce files that you can use to directly program into a part? Also do they allow free-mixing of VHDL code and schematic capture like Altera's Max+Plus II (where you can make a .GDF of AHDL/VHDL code and then use it in schematic entry)? The design flow as I know it goes something like: Come up with an idea Start a new project Write the VHDL / Schematic entry / State Machines / Verilog Fix all the errors to satisfaction so it compiles After it compiles, use a "waveform editor" and apply input stimuli and look at timing etc. Repeat above steps if timing isn't satisfactory Recompile When finished, take output file and program to part Granted I skipped a lot of important steps (timing constraints, etc) but does one tool do all of these? From what I've seen on the many products' websites, the are generally 4 components to the software package: A) VHDL & Schematic capture B) Compiling C) Simulating (looking at waveforms) D) Programming part? As for the last step however, I've always been led to believe that something like ModelSim can be used to do all the work up to coming up with the program for the part which has to be done by the part vendors' Place & Route tool? Thanks for any clarification, Vasant.Article: 22048
At Xilinx, we use the name "asynchronous FIFO" for a FIFO with completely independent write and read clocks. Such a FIFO bridges the gap between different clock domains. There is no need to synchronize such a FIFO. It does the synchronization. A "synchronous FIFO" would use the same clock for write and read. Such a design is a trivial subset of the more general asynchronous case. Sorry if we confused you by our nomenclature.

Nope, modelsim is pretty much just a simulator.
Here's the some of what's what, but by no means a complete list
Schematic capture:
Viewlogic
Aldec (foundation)
Orcad
HDL design entry
Aldec
others
simulation
Aldec (VHDL and soon verilog)
modelsim (VHDL/verilog)
viewlogic (great for schematics, weak for vhdl, no vhdl93 support)
Synthesis (VHDL/verilog to netlist with logic primitives)
Synplicity
Exemplar (leonardo)
FPGA express
Place and Route
from the FPGA vendors.
You'll need something from each category (HDL entrya nd schematic fall under
the same category). The simulator and synthesis tools have text editors and
debug features in them, but they are not very good for design entry. Veribest
is, I think a formal verification tool so it is an additional piece. Only the
FPGA place and route tools generate the bitstreams for the part. Altera has a
schematic and hdl facility built into their maxplus tools, but it locks you
into that device and toolset. You can generally mix VHDL and schematic at the
input of the FPGA tools, but you will have to instantiate one or the other
into your top level to get it all to play nice.
