#QUCS ERROR JACOBIAN SINGULAR RECTANGULAR VOLTAGE SERIES#

While I am using the Cartesianĭiagrams successfully for all other places I would use a hardware If I was using an oscilloscope, I would use the Now for my question: I am trying to discover the best way to measure aĦ0-70us pulse on a 66ms recurring signal developed in theĪbove-mentioned sim. Simulator users will of course know this already. I cannot explain why this worked in my case but I hope this informationĪnother trick I learned as a new user is to be constantly vigilant inĮnsuring that you have an adequate number of sampling points toĪccommodate *ongoing* design changes in your project. The latter resistor value required periodicĪdjustment during circuit refinement in order to buttress against future

In series with the ungrounded lead of the signal source, where it feeds Substantial positive effect was gained by inserting a 5-10 Ohm resistor Power supply rails (but *not* ground) upstream of the circuit. Simulations by placing a 0.1 Ohm resistor in series with the +12 and -12 While using this setup, I was able to substantially reduce aborted The rectangle signal source was setup with TH=66us and TL=66.6ms. Singular' error message with a corresponding abort during processing. Simulations (with a stop at 200ms), I started receiving the 'Jacobian With an analog circuit simulation that uses a bipolar power source and That I discovered on the referenced issue.Īs mentioned previously, I am a new user of this application, working I have a measurement question but first I want to pass on a work-around
