Gnucap is to be commended for being an independent circuit simulation development and open source. Perhaps there are complicated reasons for not doing so, but it seems that adding some reference to gnucap as an open source project largely inspired by the SPICE program family might be in order? ħ1.197.225.209 ( talk) 00:13, (UTC) Reply YoungGeezer 18:02, 12 November 2007 (UTC) Reply Thanks for the explanation Brews ohare 18:10, 12 November 2007 (UTC) Reply So I'm reverting the change regarding the purpose of the CMC. A better approach is being pursued now, using Verilog-AMS as an executable specification and a program like ADMS to translate the Verilog-AMS into simulator code (with some intervening steps and a bit of work). Eight or nine years ago a couple of standard interfaces were proposed, but neither caught on, because of their implicit assumptions about simulator architecture. While there are still syntax differences between the different simulators, a standard model will at least ensure that a given set of model parameters will produce a known result on each of the simulators (assuming the implementation follows the reference implementation faithfully, which is again somewhat iffy but at least there's a standard to use to beat on the implementations that deviate).Īll that said, the CMC website mentions this obliquely through the first sentence in their vision statement: "Standardized compact models for all major technologies so that customer communication and efficiency can be enhanced." "Customer communication" basically comes down to sets of model parameters to run into standard models.Īs it turns out, the "standard interfaces" thing dropped out. The reason this is important is primarly for fabless (or fab-lite) semiconductor companies, who need to take the model parameters given by the foundry and use them in various simulators. This requires standard models and standard model parameters. The CMC mainly exists to make it easy to port model parameters from one simulator to another. I feel that this article could also include information about the SPICE elements such as their function, computational methods, parameters, etc. We asked Berkeley's Regents some years ago to change spice license to new BSD (no obnoxious clause) but we got no answer. Ngspice is not covered by the GPL license, it is still covered by the old BSD license. Hello, I am Paolo Nenzi, ngspice developer. SPICE 2G.6 (1983) is the last FORTRAN version. Not currently known, but check the following for clues. If you know the answer add it to the article in the appropriate paragraph. Can someone source the assertion about the original license, and change it if necessary ?ĭoes anyone know the revision level of the first C implementation of SPICE? Hi, the article states "The original SPICE program was released under a restrictive license, which makes it difficult for others to improve upon the original software." and yet I have read in print ( I think it was in the IEEE Spectrum ) that SPICE was originally "public domain" and I think they implied it was the first "open source" program.
