Resistor Tolerance

[Abbas111977]

Hi there,
Is there a tolerance property for the resistors?
Thanks in advance

I hope I'm not misleading you, but as far as I've checked there is no tolerance parameter in models for resistor in SpiceSharp.
So I think you would need to handle it yourself by setting some random value for resistor based on initial value.

Below is code to generate resistances with some tolerance.

using System;
					
public class Program
{
	public static void Main()
	{	
		Random r = new Random(Environment.TickCount);

		for (var i = 0; i < 100; i++)
		{	
			var tolerance = 0.01; // 1% of tolerance	
			var resistance = 1000; // initial resistance

			Console.WriteLine(ComputeRandomResitance(r, resistance, tolerance));
		}
	}
	
	public static double ComputeRandomResitance(Random r, double resistance, double tolerance)
	{
		var range = 2 * resistance * tolerance;
		
		var finalResistance = (resistance - range / 2) + range * r.NextDouble();
		
		return finalResistance;
	}

Thank you very much
