Add DC Path to Ground option

News:

Spectrum Software has released Micro-Cap 9, the ninth 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.

What does the "Add DC Path to Ground" on the Preferences dialog box do?

In order to solve for the DC operating point, it is necessary to have a finite impedance from
every node to ground. The necessity for this can easily be seen because a circuit without an impedance
to ground has an infinite number of solutions and this poses something of a problem for the
simulator. This option avoids the problem by automatically adding a 1/Gmin resistor to any node
that is missing the required path to ground. Usually it is best to disable this option and provide the
impedance manually so that you know what node is involved and can better judge how to provide it
with a path to ground.
