Re: WHAT IT MEANS

Hspice, Pspice & Sspice are the different variants of Spice from different commercial companies. Their programming languages are quite similar.

PSPICE a simulation tool for electronic circuits released by Berkeley university...
SPICE is an acronym for "Simulation Program with Integrated Circuit Emphasis."

Its nothing but a netlist file where u can specify the devices and sources connectivity for simulation purpose.

Actually, PSPICE is the name of a commercial tool released by OrCAD (now Cadence).

PSPICE came from MicroSim (around 1985). It was a very nice DOS-based version of Berkeley SPICE (around 1975). PSPICE later moved to OrCAD and then to Cadence, and became a Windows app.

There is also TSpice from Tanner.
I wonder why there is no IEEE SPICE standard like there is for VHDL for example. PSpice, HSPICE, and Berkeley SPICE are all a little different.

Re: WHAT IT MEANS

There is no hope for a netlist standard for spice because each vendor add there own features to follow the user requirements. Examples are: parametric subcircuits, namespace conventions, simulation options, result storage options and uncounted model flavors.
There is an actual requirement for a standard which is driven by automatic characterisation and exploration tools. In this usage spice is only used as an engine driven by a higher layer design enviroment. This enviroment could run for example 2 HSIM for functional, 8 Spectre for DC, 6 ADS for HB and 46 Spice3F4 on a cluster system for a complex mixed signal circuit verfication. The interface is then a specific ripper for the commercial engine. It drives the netlist, commands and collects the results.
The next level of interface bypass the spice netlist and command reader and use a memory API to drive direct the matrix engine. I expect that this come only with a single vendor because there is a dramatic drop of understanding of the advantages of this approach in the design community. Furtheron the single big company trend defocus interop standards.

I have heard that there is a TCL-Spice, so a spice driven by a TCL-Script interpreter. But I think it is more focused on automation features.
