Abstract: A method includes receiving input information related to devices of an integrated circuit. A first simulation of the integrated circuit is performed over a first time period. Average temperature changes of the devices over the first time period are calculated. A second simulation of the integrated circuit is performed over a second time period using the average temperature changes of the devices. The first simulation and the second simulation are executed by a processor unit.

Abstract: A computer-implemented method for determining an amount of hydrocarbon fluid present in a rock of a hydrocarbon-producing reservoir is provided. The rock comprises organic matter and porous and permeable inorganic matter. The method comprises the steps of receiving data relating to chemical and kinetic properties of the organic matter, rock lithology data, rock thickness and reservoir temperature and pressure data, inputting the received data into a computer-implemented model, and operating the model. The model operates to a) simulate hydrocarbon fluid generation in the rock based on the input data and thereby determine an amount of generated hydrocarbon fluid, b) generate predicted data, and c) determine a total amount of hydrocarbon fluid present in the rock based on the predicted data.
