Web5. máj 2014 · Often, I do this by attaching a high value resistor from the oscillators timing components (100k ish or more - higher is preferable) to a stimulus that generates a singular pulse at the beginning of the simulation. Unless you do this, pretty much all oscillators in Proteus refuse to start.

WebA singular matrix error occurs when the circuit does not have a unique and finite solution. For example, a circuit containing a floating capacitor does not have a unique DC solution as the capacitor can be at any voltage. Also circuits with shorted inductors, voltage sources or a combination of both will fail with this error. Web10. jún 2024 · [SPICE] singular matrix: check node #L1#branch. Thanks!
