My comments: 1. In my direct experience, the free-running clock which is somehow related to this failure mechanism did *not* exhibit excessive under/overshoot. Now we are confronted with the question: what is "reasonable" undershoot? Arguably, the ISP programming circuitry should be able to sustain the same levels of undershoot as would the device in normal operation. It seems that this isn't always the case... 2. Series R term is a valuable tool, but doesn't work worth a darn for mult-load clock runs. Furthermore, it tends to slow/delay edges. In my case, the free-running clock was parallel terminated (at the end of the run). 3. Being somewhat ignorant of such things, it sounds like the input clamp diodes are sucking current out of the substrate at the clock edges, and that is wreaking havoc with the programming. If this is the case, it sounds like a nasty problem. How difficult is it to "isolate" part of the substrate from the rest of the die? > If you were informed by Altera that you needed to stop > the clock, that is incorrect information, and I apologize for the extra > work it might have put you through.

Dear readers: Altera 1998 data book states "When power is applied to an Altera device, the device initiates a Power-On Reset(POR).... The POR time is the time required after VCC reaches the recommended operating range to clear device registers, configure I/O pins, and release tri-states. Once this initialization is complete, the device is ready to begin logic operation. The POR time does not exceed 100 ms. " We are told by Altera Application support that the POR time does not exceed 50 ms for their EEPROM based CPLDs (MAX7000,MAX9000). This time is still two orders of magnitude higher than comparable Xilinx flash based CPLDs. Any one has any ideas as to why initilization after power-up on Altera's EEPROM CPLD takes that long? Believe me in our application it makes a real difference! Regards, Kayvon Irani Los AngelesArticle: 9002

When I checked out Alta Group's SPW, Synopsis's Behavioral, Exemplar, and Altera's DSP tools, a couple of years ago, None of them correctly recognized that a constant multiply by 9 of an 8 bit number, should use a 9 bit adder. Sure, they could be forced, kicking and screaming, to implement it this way, but schematics seemed far simpler. Schematic capture also provided an easy way to control the relative placement of the logic. this meant that I could build up libraries of minimized, preplaced DSP parts, for easy reuse. I'd rather spend 4 hours doing manual placement one time, than 40 hours of dubious automatic placement for every design change. I wonder if any of these tools have improved enough, in the last two years, that they would now instantiate a 9 bit adder. Would they also permit me to graphically, hierarchally, edit the placement of this adder with respect to the registers on its input and/or output? If so, I neet to re-evaluate Synthesis.

Most likely because some types of EEPROM are slow to read and even slower to write to. That's not to say that you couldn't have much faster memory cells, but that would probably increase the cost of the technology and/or the part.

POR is often a "legal cover-all" figure. A few years ago I worked for a microprocessor company and some work was undertaken on fast power-up on an existing 32-bit chip design to support low-power mode. The datasheets quoted 100mS POR - the app's engineers found that the micro powered up OK in about 20 to 100 clock cycles ISTR (about 1uS to 5uS), including a PLL stabilising. Check-out if they've actually measured it and it's not just a relic from the first version of the datasheet. --------------------- Stephen Maudsley Stephen.Maudsley@btinternet.com esgem limited Tel/Fax: +44-1453-521626 Mobile: +44-370-810991 ---------------------Article: 9005

If not, a die shrink will usually make the silicon significantly faster thus changing the best case timing numbers. If a previous design worked because of the inherent delays (known to you or not), it is conceivable that a faster part would fail. We've fixed a number of these issues on Xilinx parts since they too are continuously migrating their process geometries. Best wishes -- Ed McCauley Bottom Line Technologies Inc.

I am trying to obtain some Philips P5Z22V10-7A or -DA or IDA devices. I need at least 15, but would be willing to buy a tube of 37. Also, just one or two for prototyping would be a real help. The best lead time I can get in the UK is 13 weeks (and I have some on order). Can anyone out there help? (I know these are a bit small to count as fpgas, but this seems the closest newsgroup.)

There is a fairly well-kept secret regarding CPLDs: Although most of their configuration is directly EPROM, EEPROM, or Flash-based and thus does not require any lengthy power-on delay, some of the configuration bits, although stored in the non-volatile area, are then read out on power-up and loaded into latches. This applies to the miscellaneous signals around the macrocells, which cannot be conveniently or fast controlled from the well-structured non-volatile memory area. Certain CPLD manufacturers don't like to talk about that, because it smudges their pristine image of non-volatility. In reality, as Xilinx FPGAs have proven for the past 12 years, there is nothing wrong with storing configuration in latches. You just have to load them properly, and you have to detects Vcc dips. Hope that helps. Peter Alfke, Xilinx ApplicationsArticle: 9011
Maybe I should have posted this in comp.arch.cpld, but anyways... Vantis (AMD) and Xilinx have a ISP programming interface built on JTAG, which is great for production. Lattice have adopted this on their newer parts (thank God), which also is good. However, I'm using an older ispLSI1032E with an interface similar (but not identical) to JTAG. Not good at all. Is ther any software/equipment out there suitable for both programming the ispLSI part and perform boundary scan testing using the same simple connector. It's awkward to have two different interfaces for this.

Does this have to be from Philips? In case all you need is a low power 22V10, check out AMD's PALCE22V10Z - this is EECMOS, so it is reprogrammable. ICT and Lattice make the low power 22V10's too.

No,The storage cells in CPLD are directly involved in the operation, so they must be "read out" in a few nanoseconds, and they operate all in parallel. That's what has given CPLD their ( historic ) speed advantage. I gave a probable explanation for the slow POR in a different posting to this newsgroup. Peter Alfke, Xilinx >Article: 9016

No, the AMD parts have input transition sensing, and have low power only if nothing is moving. They are not true CMOS. In the 16V8 business there are some other CMOS devices, and I think AMD do some.

Hopefully they can expedite things for you. The CoolRunner 22V10's use the same Fast Zero Power design technique that's used in the Philips CPLDs - Hence a cross reference at 7nS and 'zero' (uA) static power doesn't exist the last time I checked. The usual problem in these cases is either a rule that Pease talked about in his EDN column a few years ago -or- difficulty in getting the distributors to actually stock a new part (they don't like to carry inventory without a run-rate history without coercion...). Pease' comment was: Semiconductor availability comes in 2 flavors: The Parts are Available and the Customers aren't; and vice-versa...

The comment on Synchronous design is right on - with these older parts, I recall there being just 1 Synch clock. If you have more - then you are running asynch. With regard to price - a higher price does not necessarily mean a part problem. In those times in my life when I wore a marketing hat, we raised prices on parts heading towards end of life as a way of pushing people away from continued use, rather than just issuing an EOL notification. We felt this was offered a more gradual nudge rather than shooting a sole source part. - Mark Aaldering Mark Aaldering mma"at"netwiz"dot"net...Article: 9022

Problems on DIE revision are more common that many realise.. 1) You should check carefully that the algorithm has not changed - and get the confirmation from as reliable as source as possible. The reflex reaction of most FAE's is 'no, nothing has changed' 2) try as many different BRANDS of programmer as possible 3) Try and get ALTERA to program some, to your files, and give them some of the (unsecured) problem devices.
