INTERCONNECT warning: maximum number of iterations reached, S parameters matrix is empty


The following warning message occurred when I ran my INTERCONNECT simulation and the ONA got empty results, Does anybody know how to solve this problem?


This warning message occurred either because there is an open circuit in the system or the s-parameter is not fully defined. Please try to add a “Termination Mirror” (Element Library – Passive – Optical – Termination Mirror) at the end of the circuit or fully define the s-parameter. By “fully define” here means to define both the forward and the backward transfer functions of the s-parameter element and also the transmissions and reflections, say for example, define all the S11, S12, S21, S22 parameters.
