OK, "implemented ... with FPGA Compiler 2". The results of the design manager are pretty close to what is promised. So the new question would be, why FPGA Compiler 2 is so far away from "reality"?

Hi, Check out User manual of VCS (if you already have it), here is an extract: VCS and VCSi are identical except that VCS is more highly optimized, resulting in greater speed for RTL and mixed level designs. Pure gate level designs run with comparable speed. VCS and VCSi are guaranteed to provide the exact same simulation results. VCSi implementation requirements are summarized in the following: 1. VCSi is invoked using the vcsi command instead of vcs. 2. VCSi uses the VCSI_HOME environment variable instead of VCS_HOME. (Also it requires separate license) HTH, Srini dfg wrote: > > what difference is between VCS and VCSi on function? -- Srinivasan Venkataramanan (Srini) ASIC Design Engineer, Chennai (Madras), IndiaArticle: 32202

HI, quiete often on VLSI implementation papers, the authors take the "pin out" number as a criteria to evaluate the final performances. If i can understand this for VLSI, i can't see why this evaluation criteria is still adopted for FPGA plateform because a first look to most of the FPGA chip package tells that a minimum of 100 IO are available (PCB overloaded ?)

Hello, Yes there is a difference between host id and ip address. Each NIC card has a unique ethernet address for that card. This is the address the flexlm uses for its license. I was able to talk to someone at Aldec, which is one the software packages I have been trying to use. It turns out that all I had to do was set an environmental variable for the location of the license file. Why this worked I not sure. I wonder if this would work for the other venders? ALDEC_LICENSE_FILE = C:\Program Files\Aldec\Active-HDL 4.2\DAT\License.dat Thanks for your help Dave Colson finish wrote: > I think there is a difference between HOST ID and IP address, > personally i changed the IP address of my PC and the tool is working > perfectly > > Dave Colson <dscolson@rcn.com> wrote in message news:<3B2F5595.8F29F729@rcn.com>... > > Hello, > > > > My computer is connected to the network, and is operating. > > "Some" versions of the lmtool do detect the ethernet id correctly > > and some don't.

I think MPEG lossiness is at times very noticeable. If you watch a DVD or digital satellite TV, you'll notice that whenever the scene changes abruptly (for example, during an explosion) the codec can't keep up and the whole screen turns "blocky" (low res) like the pictures I used to draw on the Apple II.

Hello: Now i synthesis my design with Synplify Pro6.24.Generally,i need add a file whe i use some a device(Xilinx)eg.Vertexe.v/xc3000.v/xc4000.v,etc.But now i use Spartan series,i caan't the spartan.v in /synplicity/synplify/lib/xilinx.. why are there not the likely spartan.v file?Article: 32216
I've just today tried Xilinx's new power estimation tool, XPower. XPower is "early access" software, which I think is a new code name for beta software. I'm working on a design with a tight power and cooling budget, and power estimation is difficult. The measured difference between the spreadsheet estimates and the real hardware in my past designs has been 2:1, 4:1 or worse, which might lead to wildly over designed power supplies or worse. With large power budgets in past designs, this hasn't been a problem for me, however this project is different. While the answer I get from this tool is a lot closer to what I expect (and rather less than the spreadsheet estimate), and less than my power budget, I'm wondering how accurate this tool's results are. Any XPower users that have verified results against real hardware care to speak out? This tool uses a simulation pattern out of ModelSim and the placed and routed design, so with a realistic simulation pattern I would expect a fairly realistic answer. If you haven't seen this tool yet, answer 10667 has a pointer to the download page, or search answers for for XPower. Skip the GUI, it's gakky buggy, run in command line mode. -- Phil HaysArticle: 32217
I have one which I have been too busy to do anything with. Hopefully that situation will change in the next couple of weeks. The board looks good. The software installation process is not bad except for getting a license. The license is good for 3 months. A 1-year software tools license is $995. "Steven J.

Hi, TM0 and TM1 are test pins that Altera uses to test the EPC16 device. For correct operation in user mode, TM0 must be connected to GND and TM1 to VCC as shown in the EPC16 datasheet, Figure 11.

In win95, i had to reset the pc before using netscape to reduce the instabilities. w2k is the best attempt yet at a useable windoze OS. Its got the niceties of win95, even tho its based on NT.
