MacSpice is an electronic circuit simulator. Circuit simulation is a way of building and testing virtual models of electronic devices. It is usually cheaper and quicker to simulate a design than to build a prototype. MacSpice uses a text-file 'netlist' description of the circuit as input. This is a list of components and the nodes they connect to. Users may prepare netlists with a text editor, or derive them from a circuit diagram using a third-party schematic-capture application. MacSpice then builds a numerical model of the circuit and analyses this.
A command interpreter (shell) is used to specify the types of
- Improve behaviour when executable is used as command line tool.
- Modify parsing of .options, etc. to be more tolerant of numerical values with trailing garbage, e.g. 'CJ=.2MF/M^2' and garbage.
- Modify back-quote evaluation to use posix_spawn(2) instead of vfork(2).
- Improve error reporting for 'alter', 'altermod' and
