Continuously shrinking design sizes facilitated increased integration of multitude of components on a single chip. The performance of conventional simulation methods through analog design has proven insufficient to meet the increasing demands of present mixed-signal circuits. We present an extension of the PRAISE (Piecewise Rapid Analog Integrated Simulation Environment) approach which allows accelerated simulation of analog circuits with extended applicability. In the past, this approach was only applied to piecewise-constant input stimuli (implicitly given by the digital part of analog/mixed-signal circuits). To meet the requirements of realistic mixed-signal simulations we expanded the simulation kernel to handle linear input stimuli. We introduce the changes in the algorithm and discuss runtime and accuracy compared to a conventional simulator.
