MacSpice 2.10.20

MacSpice 2.10.20 is an useful tool designed for simulating and analyzing electronic circuits. It can range in complexity from a single resistor to an integrated circuit comprising tens-of-thousands of devices. It has users who range in experience from school-age enthusiasts to retired integrated circuit designers. It is used at various universities internationally for research and teaching.

MacSpice has native support for both PowerPC and Intel architecture Apple Macintosh computers. It is derived from, and compatible with, Berkeley Spice 3f5. MacSpice incorporates many improvements to Spice 3f5 – from simple bug-fixes to entirely new commands, algorithms and solution strategies.

For example: the memory leaks that affected Spice 3f4 have been cured; new algorithms have been developed to facilitate the simulation of large circuits, and to reduce simulation time; MacSpice provides a robust multi-parameter optimizer and facilities for inter-process communication with other applications.

Enhancements:

• Enhancements:
• • Improvements to behavior and layout of graphs with log axes.
  • An 'unwrap()' function for phase vectors.
  • Sophisticated consistency checks and warnings for groups of mutual inductors.
  • The 'unlet' command now accepts the 'all' wildcard unless the current plot is the 'const' plot.
• Bugs fixed:
• • The 'xlog' and 'ylog' arguments for the 'plot' command are no longer mutually exclusive.
  • Syntax errors in '.noise' cards no longer cause a crash.
  • Functions such as length() no longer return a vector with invalid dimensions when given a multi-dimensional argument.
  • The 'compose' command now generates a uniform distribution on [0,1) instead of [0,2).
  • Cured crash when an RTF file with '.include' statements is accidentally used as source.
