Spectrum Software
Industrial Strength Simulation




Spectrum Software has released Micro-Cap 11, the eleventh generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.




Easily Overlooked Features


This section is designed to highlight one or two features per issue that may be overlooked because they are not made visually obvious with an icon or a menu item.

Tiling Windows
Sometimes when you are pondering a waveform and wondering why it came out the way it did you need to see the schematic. If the simulation is still in progress or even if it is complete, you can take a quick look at the schematic by tiling the windows. Click on the Tile Vertical or Tile Horizontal buttons and the program will tile the schematic and analysis plot windows. You can scroll the schematic to view areas outside the window.

Viewing the numeric values while the simulation is in progress
Sometimes, especially during long simulation runs or runs in which you are only displaying the last 10% of the run to avoid initial transients, you may want to see what is happening with the simulation but the plot doesn't show much yet. You can peek at what is happening numerically using the "P" key. Pressing "P" toggles the numeric display of the waveform values directly on the plot. Be sure to toggle it off when you are finished looking, as it considerably lengthens the simulation run time in small to medium circuits.

There is another way to see the numeric values during a run. You can invoke the State Variables Editor prior to the run with F12. Then start the run (with F2) without removing the Editor. The State Variables editor display will be constantly updated as the simulation progresses. You can also use the Animate dialog box to insert a key press wait after each simulation step if you want to cycle slowly through the simulation states.

After the run you can view any numeric output that you selected with F5 and toggle back to the plot with F4.
