Errors in safety-critical software can have disastrous consequences. However, tools exist that developers can use to thoroughly analyze software subsystems for critical safety properties.
Safety-critical systems have become increasingly software reliant and the current development process of ??build, then integrate?? has become unaffordable. This paper examines two major contributors to today's exponential growth in cost: system-level faults that are not discovered until late in the development process; and multiple truths of analysis results when predicting system properties through...
Pseudo random binary sequence (PRBS) signal was developed using MATLAB software and used as a forcing function in simulated second order system. The autocorrelation function (ACF) of the input signal and cross correlation function (CCF) between input and output signal were performed using MATLAB software and transfer function of the system was estimated from the correlograms. For verification of the...
This paper presents a complete framework for Verilog-based fault injection and evaluation. In contrast to existing approaches, the proposed solution is the first one based on the Verilog programming interface (VPI). Due to standardization of the VPI, the framework is-in contrast to simulator command based techniques-independent from the used simulator. Additionally, it does not require recompilation...
We consider a high performance software/hardware implementation of fault and fault -free simulation methods, and linting-technology for early design stage verification as well. Application of these technologies allows significant increasing simulation performance in comparison with software tools, and reducing design time of very high scale integrated circuits for 20-30%.
