Karen,
The Amiga version of Spice is called Aspice and is on Fred Fish disk 177. You should be able to pick it up from one of your local Amiga users groups or any store carrying Fish disks. You will need at least 1.5mb of ram to run it and it only supports the 68000, no 020s or 030s.

Any 680x0 SHOULD be ok, but it won't use floating point processors, etc. Unless, of course, it uses that one nasty instruction that you need decigel for. -don perley perley@trub.crd.ge.com

I don't really know about this myself and this posting is really a chance to solicit info. from people out there in the industry, being I most likely will do research in hardware. From what I can guess, Spice is a language/file format for describing low level hardware designs, i.e. down to the logic gate or transistor level. I have gotten to play around in a couple of CAD labs (one, Mac II's running DesignWorks; the other, Suns using GDT) and both support writing Spice files, so I assume use of Spice is pretty widespread. Now for a few technical questions. Are ASpice files usable by GDT? I don't mind too much writing small modules in L language, is Spice similar to it? Also, if anyone can correct or expand on any of the above, please feel free. Roger P. Ang (rang@ICS.UCI.EDU) Irvine? Where's Irvine? a poor Grad student at the In the heart of the Orange Curtain.

Spice is an analog circuit simulator. There is a PD version floating around for the amiga. There are some enhanced commercial versions like HSPICE from meta-software, but I don't know of any commercial ones on amiga. A lot of cad packages can either read or write spice files, so it is sometimes used as an interchange file format (what EDIF is supposed to be) between, say, schematic capture and the DRACULA layout analysis program. -don perley perley@trub.crd.ge.com

A couple of weeks back someone was asking what to do for thier senior research project, well I have an idea. Why not do a whiz bang implimentation of SPICE (Simulation Program with Integrated Circuit Emphasis). The original FORTRAN (yea, I know, yuch) source code is available (for free?) from U of C (Berkley). My Idea is to have it implimented on the Amiga, making full use of the operating system and useOCr interface in addition to throwing in some nice bells and whistles. The original program does not have circuit (screen oriented) editor or the ability to render graphs (I may be wrong), but most of the grunt work has been done. The only thing missing is the user interface. As it stands now, the program accepts text input in order to define the circuit and operating characteristics of the components, and create a file of numbers for a post processor to the actual screen or hardcopy rendering of the graphs. The only implimentation with which I am personally familiar is MicroCAP II, student version for the MS/PC-DOS machines. Its an OK, certainly not fantastic, compiled basic implimentation, but suffers from a poor user interface. This is a great program for checking out ideas without having to wire-up a circuit and scoping it. IEEE Spectrum has an overveiw of several circuit simulators for different enviroments (PC's to mini's) but no Amiga ... :( This definately should change! :) I think that the source is available from: Department of Electrical Engineering and Computer Science The University of California Berkley, California (I'm sorry that I can't give a more complete address) PS: Yes, I know that there is a PD version somewhere on FF, but I am hoping to generate some interest. ------------------------------------------------------------------------------- Andy Nagy(student) ,The University of Western Ontario, London, Canada USENET: 4224_5206@hydra.uwo.ca (I think)

There is a version of Spice (3C1) written in C that runs over Unix or MSDOS. 3C1 would be a better starting point for an Amiga port than the older Fortran versions, eg 2G6. 3C1 also has a rather nifty display program called nutmeg - a vast improvement over the line printer graphics 2G6 provided.

The only thing missing is the user interface. Uh... Hold on. Have you seen IntuoSoft Spice (by IntuoSoft, duh). I really like what they did. IntuoSoft Spice has a graphic preprocessor, you build the circuit by selecting the components you want from a menu, and the preprocessor writes a Spice version 2 compatible input file. There are several advantages to using a preprocessor, you don't have to mess with the Spice source at all (not something to be doing unless you are a Numerical Analylist AND an Electrical Engineer), the executable will be smaller (something to think about on small systems), and you can STILL run the Spice text file on any Spice version 2 system if you need more power. >As it stands now, the program accepts text input in order to define the >circuit and operating characteristics of the components, and create a file of >numbers for a post processor to the actual screen or hardcopy rendering of the >graphs. IntuoSoft Spice also includes a graphical postprocessor to plot Spice version 2 output files. The advantages of a graphical postprocessor are more or less the same as the advantages of a preprocessor. For instance, Spice output from a mainframe can be plotted (not just Amiga Spice output). (I started on one myself but I didn't get very far...) The preprocessor and postprocessor could communicate between each other with Arexx ports or you could extend the Spice instruction set by adding additional cards using the Spice remark specifier '*' (again, like IntuoSoft Spice), for instance *plot. I've thought about this alot, maybe I should pick the project up again... I hope this doesn't sound like a huge add, I don't work for IntuoSoft. --George

Please?? Actually, what would probably be better, more in the spirit of Amiga programming anyway, would be to compile it under 2.0 using the new 2.0 math library; it automatically selects the coprocessor for floating point math if one is available. I don't think this route would be usefull to people until everyone is running 2.0, but neither is the option with inline coprocessor code (unless you have a coprocessor). --George

A second version with inline 881/882 code would be nice because we might then get to the 8x or even 10x faster mark. Also, as I have said before, there is a program to plot SPICE files called SPlot, available via ftp at sunne.waterloo.cs (I think). It should soon include ARexx support for full automation, at which point I would expect it to be posted to c.binaries.amiga. This program also supports extra functionality not found in SPICE like plotter output, arbitray zoom etc. Stephen > --George
