Circuit Lagging #651

Open renanbertolazo opened 2 years ago

renanbertolazo commented 2 years ago

Hi, is there any way to make large circuits make less lag? I'm doing some large circuits but is very laggy and i can't even use them.

There are some tricks you can use. Can you send one of the circuits?

Prova8.circuitjs.txt this one and this one Ram_16x4.circuitjs.txt

pfalstad commented 2 years ago

Those are some big circuits. I don't have any tricks that would help, I don't think. I had some ideas to optimize large circuits like this, but I'm not sure when I'll get to it.

Ok sr, thank you very much :)

I am having similar performance issues with my circuit.

I used the file "Prova8. circuitjs. txt" from the questioner of this issue for testing，For large circuits, use the default step size of 5 μ s. The calculation is slow, even if the step size is adjusted to 500 μ s. Still slow, use sparse matrix and adjust step size to 500 μ s. The performance improvement for large circuits is very obvious, and I may have forgotten to tell you that large circuits need to adjust the step size to 500 μ s. Even larger step sizes can be adjusted according to the size of the circuit,

Using a better sparse matrix structure can be faster and support larger matrices. Below are the test results: Refresh Time (Sparse Matrix LU Decomposition) Matrix Size
