Release 18
----------------
Rework-18 is introduces several new features into ngspice. This is a major
release that comes after more than three years. During the silent years
ngspice developers worked in CVS to stabilize and introduce new features
into the simulator.
- Tclspice simulator library has been merged with ngspice. Now you can
compile ngapice or tclspice by asserting a configure switch. See README.tcl
- New options have been introduced: brief, listing, autostop and scale
- Support for .lib file has been introduced. This allows the use of
third party model libraries in ngspice.
- .measure statements: avg, integ, rms, max, min, delay, param
- .global statements t support for global nodes whose name is not expanded
when flattening the netlist.
- .func macros for inlining functions into netlists.
- Improved the numparam library to support fully parametrized netlists.
- BSIM model binning.
- new multi-input gate VCVS using XSPICE extensions.
