If the FF has an asynchronous clear, the D input is one, and the clear is released just before the clock edge, the FF can go metastable, and might resolve to one or zero. If the FF has an asynchronous clear and the D input is zero, there is no chance of a metastable result. So the only FF that can go metastable on the first clock edge after reset is the LSB. That may well mess up a SDRAM controller, but will not cause this circuit to do anything other than have the extra delay of the metastable resolution time if that slips past the next clock edge. Which is acceptable, as all we are hoping for is a clear release from reset for the rest of the design. >For the SRL16, yes, you are correct, the metastable performance sucks. >I should have been more exact by stating the SRL16 should be preceded by >a flip-flop.

Hi, all. This is Tomoya greeting from Japan. I would like to hear about Altera Stratix-II ES(engineering sample)/MP(mass production) differences. Here is background of our isse (we're facing); We'd made three DDR evaluation boards using Altera Stratix-II EP2S180/130. It has DDR interface, DDR memories, and many IOs (GPIO: General purpose IO). At first, we used EP2S180/130ES (engineering sample, working sample) because of delivery. It worked well. DDR worked well and GPIO ran at 200 MHz (or more) data communication speed between one board to another board (board to board). After that, we'are now making same evaluation set. We use same PCB bare board, same devices/parts ... only differences are that we used EP2S180/130MS (mass production. Of course, same speed grade!). However, the new one does not work well. It works when we drop its speed (from 200 to 150 MHz). We're now guessing it has clock problem. Especially, FPGA internal PLL. Does anyone has had/faced same issue? Does anyone knows any differences between ES and MP of EP2S180/130? If you have any issue/information about these, let me know. It helps our work and of cource I would like to post it for your progresses. Best regards, --- Tomoya <http://www.accverinos.jp/english/english.html>Article: 92452

Do you use any bus control signal (RD in combination with CE for the ADC for example) to trigger the logic analyser? If not, you are just measuring all bus activity, not just the output from the ADC.

Hi Olaf, shame on me. I have synthesized, but not simulated my source. A simple change of my code like this: total_sum <= ('0' & a)-('0' & b); would do the trick and give you a 17 bit result. Wether you call the MSB carry out or not depends on you, but it's no longer ignored. Of course the use of the resize function, like Andy Peters showed us, is to prefer, for its a more general solution. diff := resize(x, diff'length) - resize(lower_bound, diff'length); So, have a nice synthesis (after simulation) :-) EilertArticle: 92459

And I am not. this PHY_EN signal, what does it drive on the processor? I can imagine that it just signals the processor data is available and that consequently, the processor issues bus cycles (set an address or CE, activate RD, read data, deactivate Rd and CE) to read the data. This means that data on the bus during this 30us is not data from the ADC all the time. Only when the ADC is read during the bus read cycle, valid ADC data is readable on the bus.

Watch out for "feature creep" also, i.e. requirements / specifications changing as you're going along. How you handle that will probably be make or break for your project. It's a very difficult tightrope between frustrating the people who are waiting on your chip (regardless of whether it's customer specific or mass market) by playing hardball with a formal change request procedure, or frustrating your team by agreeing to spec' changes without agreeing schedule impacts arising from those changes. Doing project management can be very challenging, keeping all those plates spinning in the air at the same time, but it's very rewarding when you hand over the development at the end. Don't take it personally if the development gets canned, it happens a lot in our industry. I've never seen a bad project manager be the root cause of a cancellation, it's usually external like missing a market opportunity or whatever. In which case you can pin it on your product marketing people (or your top-management, or your end customers) for being too far behind the crest of the wave. Last word, but in my personal experience I think women make better project managers, as they're naturally gifted multi-taskers, and usually have better sift skills than typical male engineers. Not always, but on average. AlanArticle: 92464

All the module tests go great > but then it doesn't work when you put it together. This is a common issue to all of us, and due to poor specifications. Engineers (and management) hate the time to put down a thorough specification 'because we could be actually implementing something', but when modules don't work together because they did *not* do a thorough spec, it takes longer and is far more frustrating, to say nothing of being hazardous to your current employment position. One of my cardinal rules of project management is --Have a thorough specification of the task--. Thorough spec: Any three of your engineers can read it and **will all get the same result**. If three different engineers read that spec and do not agree on what it means, it is not a properly written spec. > > The other is that halfway through a project, the nature of the > work changes.

I usually allow a fair amount of time (depending on who, what etc) for 'mode changes' Product definition Spec writing module implementation Integration testing Each of those is a major section and should have some time between them for the team to 'change focus'.

The issue in hardware (well, reasonably fast hardware) is bloat, by definition, is a bad thing[tm]. Taking a fairly standard for instance, let's implement a simple memory interface, but with a wrinkle; the bus has a *minimum* speed (such as DDR). Now you can't just run it a little slower - the memory devices *won't work*. For such an application, a thorough knowledge of the interface (and the chips on the other side of the design) is a pre-requisite. It's no good saying do this, then that. Earlier in the thread, I noticed some compilers automatically register everything. The problem there is now we get resource utilisation problems and we *can't route* and meet our timing criteria. So, before we get to the 'advanced type of tools such as software has', we must first make them efficient and non-bloating. Just my $0.02 Cheers PetesArticle: 92469

I understand what you mean now. PHY_EN is a stable signal, while my clock period is 25ns, in each frame, digital side is sending some 1200 I/Q samples, one pair of samples each cycle and unchanged throughout the clock cycle. From the datasheet of ADC, I don't see there is any Rd or CD signal, it's as plain as ADC outputs are hold stable and change every 25ns. After all is done, I think I had better flag a "faulty ADC board" message to the up layer. since even when I disconnect ADC input, many of the pins mentioned below still to high level, sampled by a logic analyzer's 400MHz clock. Left channel, bit 7,5 stick to 0, bit 9,4 switches during active, stick to 1 in idle mode, bit 8,6,3,2 switches during active, stick to 0 during idle (I expect 9:2 of both channel to behave in this manner), bit 1:0 are switching during idle and active (noise during idle mode).Article: 92473
