Macintosh silicon layout and simulation software. Create semiconductor and optical circuit designs, and test them out before fabrication.

  • The initial release featured basic layout abilites, 5-function variable equation support, and basic GDSII format exporting.
  • The second release added full support for saving and loading files associated with the .fdtd extension. This is an format I've introduced just for this program.
  • Multiple documents are now also working, so there can be multiple schematics being worked on at the same time.
  • The best thing about the 2nd release is that both Layout Index profiles and Layout Permeability profiles are now working.
  • The third release added a preliminary simulation engine, and an updated animation window.
  • The simulation engine cannot yet properly support some materials and sources, and sensors are not yet implemented, so results are purely qualitative
  • The fourth release switched to a new format for saving & loading simulations, note that its incompatible with the previous saved simulations.
  • There is now slight support for extending simulations, so a simulation can be loaded, then pick up where you left off. This is still incomplete.
  • Other internal changes for code maintenance and performance.
  • 5th release: Better support for indexes, permeabilities, conductivities, with profiles
  • Snap-to-grid, and revert to selection cursor options
  • Simulations can be cancelled while running
  • The fifth-and-a-half release brought clipboard functionality, shape rotations, tooltips, and the duplicate & delete tools
  • The sixth release added a full layout scripter, with no arcane typing, just an easy-to-use clickable interface
  • There is a demo script hosted on the dev page
  • A plugin system has been added for analyzing results, and included is a basic E-field plotter. Rest assured, I will have better plugins coming along.
  • As per the 7th release: there is now full and working support for simulation extensions
  • Also included is far more included documentation
  • Undo now works in simulation and shape configuration info
  • 7.5th release: TONS of bug-fixes
  • GDSII importing (path support still being worked out, boundaries and boxes are ok)
  • Trig functions in any equation (sin, cos, tan only for now)
  • sensor data export plugin for external data analysis
  • a better demo file on the website

What is new in this release:

This is the 8th release.

  • Full GDSII importing support: paths!
  • Exponential, not linear zooming
  • Auto-fit to layout button
  • Far better plugin support

Requirements:

Mac OS X 10.3 or higher (may work under 10.2)
