Abstract: This paper is going to put forward a reused method basing on the AHB bus.This method is based on the eRM (e Reuse Methodology) of Verisity.By increasing configurable environment variables in each of eVC files, and then making use of the basic architecture of SOC automatically generated by the script languages, when you verify different design protocol, only need to extend the basis of the verification environment architecture.So this method will gain the reused verification of every design that is based on AHB bus interface and improve the efficiency of verification highly.
