This paper relies on the longest closest subsequence (LCSS), a variant of the longest common subsequence (LCS), to account for noise and process variations inherited by analog circuits. The idea is to use stochastic differential equations (SDE) to model the design and integrate device variation due to the 0.18μm fabrication process in a MATLAB simulation environment. LCSS is used to find the longest...
Today's analog/RF design and verification face significant challenges due to circuit complexity and short market windows. In particular, the issues related to noise modeling and verification still remains a priority for many applications. In this paper, we propose a methodology for modeling and verification of analog/RF designs in the presence of noise. Our approach is based on modeling the designs...
Analog and mixed signal (AMS) circuits play an important role in today's System on Chip design. They pose, however, many challenges in the verification of the overall system due to their complex behavior. Among many developed verification techniques, runtime verification has been shown to be effective by experimenting finite executions instead of going through the whole state space. In this paper,...
Mixed-Signal extensions to VHDL, Verilog, and SystemC languages have been developed in order to provide a unifying environment for the modeling and verification of Analog and Mixed Signal (AMS) designs at different levels of abstraction. In this paper, we model the behavior of a set of benchmark designs in VHDL-AMS, Verilog-AMS and SystemC-AMS and compare the simulation performance with HSPICE. The...
