This paper examines the accuracy of an abstract dynamical model for continuous-time analog iterative error-control decoders. An existing compact dynamical model formulates iterative decoding as a fixed point problem. The dynamics of each analog cell are modeled by a non-linear differential equation with a single time-constant, which is solved numerically using Euler's method. We propose a fitness test to evaluate the accuracy of this abstract model. For randomly constructed codes and random stimuli, circuit descriptions are synthesized using both the abstract dynamical model and SPICE. A comparison is performed to measure the correspondence between the two simulations for codes of increasing length and complexity
