I have noticed that PDF files of my Orcad schematics are not perfect. For example the resistors are made of lines that are a little too long. But they are very readable and can be printed in any size. A coworker (in another location) uses a Design Works and produces good PDF files that I have no trouble reading. When you say you have been far from successful using PDF, what sort of problems do you have? I don't think HGL files would be very useful. I don't think many viewers can read them and they are not even easy to print unless you have one of a handful of printers. I don't use postscript because my attempts at using Ghostview have not been very successful. I don't remember what problems I have with it, but I seem to recall that it crashed and I was never able to view a file. Likely an installation error. But that is the sort of problem I have with most applications I try to run that come from the Unix/Mac world. Mixing PCs and other computers just don't seem to work. The only way I have of viewing my coworker's PC board layouts is directly from the gerber files since he can't produce a PC readable graphic file with his software on the Mac. He says the file format is older than what can be read on the PC. I can't remember if he was talking about a TIF or a PIC file. -- Rick Collins rick.collins@XYarius.com remove the XY to email me.

Does anybody now how I can get the hold time requirement between an external pin and an internal Flip-Flop ? I want to make sure that my PCI logic meets the 0-hold-time requirement. For Virtex there are pin-to-pin values in the data sheet but they only apply to IOB FFs. As far as I can see the only way to check this is via a post-route simulation with a min delay SDF hacked to set the PCICLK delay to max. BTW: In the latest BitGen documentation it appears to be possible to put a delay on the GClks but your are told to do this only under instructions from Xilinx. Has anybody worked out how to use them ?Article: 18507

Big architectural differences. Which is best depends on your application. For signal processing, Xilinx is a hands down winner. For other apps, the Altera is better.

One extra note regarding pdf. You need to print to the distiller, not to pdfwriter. The graphics are too complicated for pdfwriter. Using PDFwriter will make a mess of things-missing lines, wrong length lines, random scaling and things like that. I've had good success printing to pdf as long as I use the distiller as the printer. rk wrote: > hi, > > i wish to publish some schematics for people to view on the www. before > i start on this project, i thought i'd solicit some suggestions. > currently i have a viewlogic license but haven't had the greatest luck > with doing much with that wrt sharing schematics; perhaps i need to > fiddle with it more. i also have veribest but haven't really explored > that at all so perhaps someone with some experience has some ideas or > thoughts. > > i could do .hgl (hp graphics language) output but not sure how readable > that would be. usually when i import an .hgl into word it makes a mess. > > likewise, printing to .pdf has been far from successful. > > so, > > what's a portable way to share schematics here, approaching 2000, in the > so-called information age? :-) > > suggestions? > > rk -- -Ray Andraka, P.E.

I've had to wrtestle with this problem from time to time myself, and have not found anything that works better than either PCX or BMP format, so long as your intended audience uses Win9x, which provides handlers for those formats. Several schematic/PCB packages have HPGL viewers, i.e. allow importation of HPGL drawings, but I've not found a schematic capture package for Windows that satisfies my requirements, so I still use a 10-year old DOS-based one (OrCAD), which, by the way, doesn't import HPGL, but their PCB package does. It's not perfect, by any means, however, as text often gets muddled to where it can't be read. If you find a solution, please share it with me. thanx Dick On Wed, 27 Oct 1999 17:33:41 -0400, rk <stellare@NOSPAM.erols.com> wrote: >hi, > >i wish to publish some schematics for people to view on the www. before >i start on this project, i thought i'd solicit some suggestions. >currently i have a viewlogic license but haven't had the greatest luck >with doing much with that wrt sharing schematics; perhaps i need to >fiddle with it more. i also have veribest but haven't really explored >that at all so perhaps someone with some experience has some ideas or >thoughts. > >i could do .hgl (hp graphics language) output but not sure how readable >that would be. usually when i import an .hgl into word it makes a mess. > >likewise, printing to .pdf has been far from successful. > >so, > >what's a portable way to share schematics here, approaching 2000, in the >so-called information age? :-) > >suggestions? > >rk > > >Article: 18522

Xilinx is the hands down winner in far more applications than "just" signal processing. :-) Then again, you (or I) might say that all applications are "signal processing" of one type or another.
