Behavioral abstraction of HDL models for simulation performance

International audienceThis article focuses on the behavioral abstraction methods of VHDL models for the improvement of event-driven simulation performance. The model abstraction takes into account the specific simulation requirements in a particular simulation execution: the observability of the internal and external signals as well as the testbench vectors of the input signals. According to those requirements the initial model is abstracted in order to decrease its complexity in terms of the number of VHDL objects used, but also in terms of the elaborated model memory usage. The practical results of the simulation performance improvement comparing to the conventional simulation are presented
