--------------65317FF9095A21B27AA79D13 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit John, There's probably a problem with one of the JTAG pin connections. This error message is caused by: - Cable powering problem - Device powering problem - JTAG pin connection problem. The good news is that you're using a package that you should provide you with access to the pins. I would start by hooking an oscilloscope up to the TDI, TDO, TMS, and TCK pins on the device, using the Debug Chain feature in iMPACT (File -> debug chain) to toggle them (alternatively, you could use IDCODE looping to drive the three input signals). Look to make sure that the signals are actually switching and that there isn't excessive ringing or noise. My suggestion is that you actually put your probes on the pins of the device - not on the breakout board. There could be a problem with the socket adapter or the breakout board, so you should start by determining what the device is actually seeing, and move outward from there. Last, you should be aware that iMPACT does not support all 9500 devices (see Xilinx Answer Record 12737 for more information about this). Note that all 9500XL and 9500XV devices are supported, though. This limitation would not cause the problems that you are seeing, however - iMPACT will be able to at least detect the devices in any JTAG chain, regardless of the number or type of devices.

Rick, I would still do the IBIS simualtion to see if the 5V is really there. Also, Virtex is 5V tolerant without any resistor at all (ie 5V PCI interface IO standard). It is only in Virtex E and later parts where the resistor is going to be (possibly) required. Austin rickman wrote: > ATA is correct.

When I last checked, the prices were surprisingly 'linear', at appx $1/32MCells so there was little pressure either way. The PCB layout and mechanics can have more impact. If it is a relay drive / LED drive, or wire type load, more modular IO can be a good idea. If it is driving a single LCD display, then a single CPLD makes more sense, but CPLD's cannot cover all LCD driver space. > >> > >> 5.

I've been told 1c/pin is appx the package-flow cost, so you will not get close to that. If you need 150 x 5V -> 10V post pin buffers, you will balloon further. -jgArticle: 44379

Your friend might want to change that option to speed, to see how LeonardoSpectrum will do. Another thing to consider is, does your design meet whatever timing requirements with either tools? Often time, when you optimize your design for area, it is likely not to meet timing requirements compared to optimizing it for speed. > Today I got the offer from Altium: > > Leonardo Level 3 -- NodeLocked US$ 21.875 > Leonardo Level 3 -- Floating US$ 32.815 > Leonardo Level 3 Single Vendor -- Nodelocked US$ 13.690 > Leonardo Level 3 Single Vendor -- Floating US$ 20.625 > Optional Schematic Viewer Leonardo Insight Nodelocked -- US$ 5.625 > Optional Schematic Viewer Leonardo Insight Floating -- US$ 8440 > > If it was about 8k to 10k, I would buy it immediately. > Does Altium resell Mentor Graphics software? Anyhow, I read a press release by Mentor Graphics that the list price for LeonardoSpectrum Level 2 is $8,000. I am totally sure about the current pricing for Synplify, but I read a press release a while ago that said it was $9,000. > Maybe Ray is right and XST will get better with future ServicePacks ? > I won't count on that. I recently used an XST from WebPACK ISE 3.3WP8.0 (XST Ver. D.27), and the QoR of it was pretty much same as an XST from ISE WebPACK 4.2WP2.0 (XST Ver. E.35). That probably means that other than bug fixes and support of VHDL syntax, XIlinx hasn't made much improvement to XST. Plus, the tri-state buffer "bubble up" issue and valid FFs disappearing when blackboxes are used and the design hierarchy is flattened bug have been there as far back as XST of WebPACK ISE 3.3WP8.0, which means that perhaps Xilinx isn't too interested in fixing problems.

The ATA standard only specifies (5v) TTL level signals. AFAIK, it is up to the manufacturer to choose whatever logic family he wants for the disk side of theinterface provided he fits within the specification. SInce you normally will not know what device the manufacturer is using (and if you allow use with any drive), you must accept any signal level that conforms to the spec. Likewise, I sincerely doubt you will be able to get IBIS models for the drive, and even if you could they would only be for a specific drive. The data bits on the bus are bidirectional, so you will have considerable trouble trying to get the resistor trick to work reliably. I highly recommend using one of the 5v tolerant devices to interface to the disk, otherwise, you are going to need to use a level translator to interface it. For Xilinx families that means either the original Virtex or SpartanII (not E) for new designs. rickman wrote: > ATA is correct.

A systolic array is an array of similar processors operating on data passed from the previous processor, kept itself, and sometimes passed from the subsequent processor. Usually they are special purpose, and contain a fairly large number of processors. Pipelined architecture is used to implement parts of a more general processor, such as the multiplier or divider of a processor. Usually the pipeline is relatively short, as this specifies the latency. If this is homework, please reference the newsgroup. -- glenArticle: 44387
Its good that I learnt some more features of BlockRAM (I am new to this). Thanx Peter. Still I have some questions. Suppose the data output of one of the dual ports which I am using as read port is directly connected to the data bus of the system. Then, FPGA should put data onto the databus only when the system master selects the FPGA device AND gives the read clock. But as I see in the dual port BlockRAM module, whenever there is a clock, data is read and put onto the port unconditionally (may create clashes on system databus). Eventhough controlling the "read address latching" is possible, controlling the "read operation" is not possible. Is the above argument correct? If so, Could you please tell me what to do in such cases (reading conditionally)?

My design has a big FIR, comprised of blockRAMs and pipelined adders, most of which I had to hand-place with a Perl script to meet timing. There are 64 adders, each with two 18-bit inputs and a registered 19-bit result. My script placed the output registers of each of the 19 flops for all the adders. As is to be expected, the Xilinx (4.2 sp3) placer put the requisite LUTs and carry chains in a row, lined up next to the output registers. The exception was that in each of the 64 adders, the LUT that adds the two most significant bits was placed haphazardly, not in line with the rest. Some were fairly close, while some were as far away as they could be and still remain on the die. These paths all failed timing, of course. I finally had to modify my Perl script to place these LUTs in the correct position next to the output register. Since these are named by the synthesizer I don't like doing this because the names can change after synthesis. I shouldn't have to do it anyway. Has anybody else seen this?

Hello, From a single recent very unofficial PC performance comparison .... Target: Virtex II XC2V6000 Xilinx: ngdbuild, map, par, trce using Design Manager. 4.1i, sp3 PC A: 650 MHz Pentium III, 1GB PC100 Execution time: ~1 hr: 30 min (+/- 5 min) PC B: 2.4 GHz Pentium IV, 2 GB PC2100 Execution time: 40 min Caveate: This is only one comparison of a single run on each computer. Most of the time (A: 1hr, 11 min B: 35 min) was spent in par, where the CPU utilization was 100%, according to NT 4.0, sp6 task manager. par execution time ratio: 71/35 ~= 2.03. Memory speed ratio: 266/100 ~= 2.66. CPU speed ratio: 2400/650 ~= 3.69. Although CPU utilization was 100%, the execution time ratio seems to imply that memory bandwidth was the limiting factor. But, the CPU was not <100%, so it's unclear why the execution time was not shorter. (IOW, I don't know what else the CPU was doing.) Screen saver, virus scanner, email, etc. were off. I've heard several times that FPGA tools are CPU intensive, but I think that machine specification should consider factors in addition to CPU speed, e.g., memory bandwidth, size of memory (to hold database), and M/B/chipset. We also considered a dual-CPU M/B. Unfortunately, no tools, that we have, can take advantage of multiprocessor PCs. A multiprocessor PC, in our case, would allow us to do synthesis/simulation, while the Xilinx tools are running. (I've tried to script the flow, but cannot since we're using ChipScope.) I believe that Xilinx on Linux needs Wine (from Xilinx installation notes), which I "heard" elsewhere ends up being slightly slower than native code. For front-end tools, we use the Mentor tools, which I believe have been ported to Linux, but, I haven't tried any, yet.... (I've been hoping ISD Mag will do another "annual" comparison.) Microsoft and Linux seem close as fas as speed, but, Linux seems to be ahead wrt stability. I haven't used Altera since the Flex 10K and MaxPlusII, so I don't have any experience with the latest Altera FPGAs. I also have no experience with the Xeon CPUs.

Not silly, but probably better posted on comp.lang.verilog I guess you already know about Verilog "primitives" - they are a kind of predefined module. All the usual gates (and, or, xor...) are available. Primitives are different from modules in three important ways: 1) you do not need to supply an instance name, so this is OK: // an instance of the 'and' primitive with an instance name and U1 (out1, in1a, in1b); // an instance of the 'and' primitive with no instance name and (out2, in2a, in2b); 2) the parameter override syntax is used not to control parameters, but to specify a propagation delay for the primitive instance 3) the number of ports is variable for some primitives: for example, this is a 4-input AND gate: and My_4_input_gate (out3, in3a, in3b, in3c, in3d); There is a family of primitives representing bidirectional pass switches or transmission gates: tran(A,B) is a link between A and B tranif1(A,B,E) is a transmission gate between A and B, enabled by a high level on E tranif0 is the same as tranif1 but has active-low enable. There is also a family of unidirectional switch elements intended to model MOS transistors used in transmission-gate logic: nmos, pmos, cmos. Using the tran elements gives the simulator some extra work, and makes it more difficult to do mixed VHDL/Verilog simulation. -- Jonathan Bromley DOULOS Ltd.
