However, if there are errors or ill-defined program parameters an incorrect or no solution at all may be the result. For most well-defined problems, convergence is possible. Success or convergence is achieved when values for all variables can be found such that there are no violations of the constraints. Most often, the algorithms for these programs are iterative optimization techniques. Common Circuit Convergence Issues and ErrorsĬircuit analysis is typically performed by bounded dynamic programming, where there are a number of variable values that must be determined simultaneously and within constraints. Let’s see what types of circuit convergence issues and errors can occur during the simulation and how they can be avoided. In this condition, your simulation would run until infinity. If no solution is reached, there is some error or your program may be getting stuck in an endless loop. However, signal analysis is done by mathematically evaluating a digital model of your board’s circuits and depends upon a solution being obtained or the program coming to an end. The ability to simulate your board’s behavior when signals are applied is invaluable, especially for multi-board PCB systems. For example, nothing can be proven to be true unless it is true for all time or until infinity.Īlthough essential for mathematics, infinity can have negative connotations for digital programming which is used to perform the circuit analysis for PCBs. In fact, most mathematical fundamentals only survive if infinity exists. However, mathematics which is the basis for our understanding of the world easily incorporates infinity. There are minutes, hours, days, weeks, months, years, centuries, millennia and so on. And, time itself is not immune from this finite classification. After all, we define almost everything as having a distinct beginning and ending or start and finish. Infinity is one of the concepts that can be hard to grasp.
