XESS Corp. is releasing the fourth section of its "myCSoC" tutorial for free downloading at http://www.xess.com/myCSoC-CDROM.html. We will release a new section each week. Each section describes a design example for the Triscend configurable system-on-chip device (CSoC). The Triscend TE505 CSoC integrates an 8051 microcontroller core with a programmable logic array to create a chip whose software and hardware are both reprogrammable. The tutorial examples show how the Triscend FastChip development software is used to configure the TE505's programmable logic into peripheral functions that cooperate with the microcontroller core. -- || Dr. Dave Van den Bout XESS Corp.

Hi, Does anybody know the big difference between fundation serial s/w and Alliance serial s/w? I have to choose either using Workview Office plus Alliance tools or using Fundation serial. But I don't know which option is better. Any help would be appreciated. ZhibinArticle: 23979
Thanks to all who responded to this. In addition to the responses posted here, I got about 10 via email. The consensus (~80%) is that housing cost is a major problem but there is some tradeoff of longer commute time for better housing. A few people pointed out that with good floorplanning, you can optimize your commute to go against the rush hour traffic.

I don't know what you mean by "serial", but the Foundation software includes Aldec schematic capture software and if you buy the synthesis version, FPGA Express. Neither of these tools is the "premier" tool for FPGA design according to many designers. Many prefer Viewlogic for schematic. I have used both and like Viewlogic a little better than Aldec. The busses in Aldec are a real PITA. Also, the files that Viewlogic saves are text and so can be version controlled a little more efficiently, easily. But both will do the job. The support is also an issue. Xilinx provides the entire Foundation package and so directly supports it. The Viewlogic package is not directly supported by Xilinx which can sometimes cause difficulty in getting answers to questions. The HDL synthesis is another issue. FPGA Express is clearly not as good as some of the other tools available. But it is much cheaper in the Foundation package. So you get what you pay for (sometimes).

I would recommend Tucson, but then again, I'm from New Jersey. And the
typical silicon valley shack cost three times what I paid for a 2000 sq ft

Article: 23985Hi all, I've posted this before but no-one answered so here goes again... What pin's would I need to erase locked devices? I have a few devices of the above with the JTAG port disabled, I made an error in my programmer, and now I need to erase them. I have been told that I'd need a third party programmer to do this, but surely I only need to design a board for myself. Has anyone ever done this, or have any links that I could find usefull, I've done a bit of surfing around but found nothing as of yet. Thanks Mike. PS. I hope the no replies aren't anything personal... (Mister Paranoia jumps on my shoulder)Article: 23986

Ah, finally an answer to my original question. Thanks, Ian! Paul In article <3975A3FD.84DD392A@lucent.com>, "Ian J. Smith" <ianjs@lucent.com> writes: > We've had great success with Xilinx DP RAMs here. The tools are rather >good too. Altera still have some catching up to do.Article: 23988
Dick, The longest 'wires' in the silicon can be ~20 mm. The voltages on this wire are in the 1-2 volt range, so a disturb voltage would be ~100 mV. So, your problem is one of: if I have a wire 20 mm long, what magentic field induces 100 mV on the wire at distance X. Any physics students out there to solve Gauss' equations to see what the induced electric voltage is from a 3 Gauss 60 Hz Field with distance from a 20 mm wire at the best orientation?

No. My old phyisics book says:
induced emf = mag field*area/dt
1 Weber = 10000 Gauss
mag field = 10 Gauss = 1/1000 Weber (say)
area = maximum possible loop = (2cm) squared (say)
dt = 1/100 s (approx.)
emf = (1/1000)Weber * (0.02m * 0.02m) / 0.01s
= 40uV
That's not going to hurt anyone.

I think I may have the answer, applying 11v to the TAP pins may re-activate the jtag port. Does anyone know if this is correct or not?

You should ask "what company's marketing department should I be working for?" How many "gates" this translates into is another story but the F5 and F6 muxes makes the Virtex CLB very powerful in terms of 4 input LUTs.

Does any body know when will the new version of Xilinx Student Edition with Foundation 2.x be out? Since coming to know that there will be a new version shortly, I am holding on from buying the new version for about two months now. The wait is killing me. Pratip MukherjeeArticle: 23994

I was just kidding about that. I understand that Xilinx is trying to show that there is more in the CLB than just 4 input LUTs. But it is common in many FPGAs to have a little more than the basic element. Lucent FPGAs are the same way. My point was that I already understand the issues of how to use the CLBs, I am just trying to get clear information on the actual LUT counts in the various sized FPGAs and the way Xilinx counts them makes me do extra work. If they would just publish the actuall counts of LUTs instead of the marketing number, I could just refer to their data sheets instead of having to keep a spread sheet with this information from the various manufacturers. Gate counts are the most worthless numbers I know of. It is alot like the MHz rating of processors. I have *NO* idea of how to compare a PowerPC processor at 600 MHz to a Pentium at 600 MHz. The one thing I am sure of is that they are not the same! So I am also sure that a 50 K gate Xilinx part is nothing like a 50 K gate Lucent part. But if I am not using block RAM, I do know that I can get the same design to fit in two parts that have the same number of LUTs (or at least close).

Does any JEDEC to VHDL converter exist to allow me to quickly migrate old
circuit card designs based on rafts of 22V10s in DIPs to a single large FPGA?
Either freeware or from a FPGA vendor? I've researched it enough to know I
could do it, but figured it was so obvious someone else must've already done
it, though I don't see it mentioned in any FAQs I've found.
Thanks.
