FAST SIMULATION METHOD FOR INTEGRATED CIRCUITS WITH POWER MANAGEMENT CIRCUITRY |
摘要 |
<p>In a fast simulation technique, the output node of a power supply module of the integrated circuit can be designated as an ideal power node. At this point, the power supply module can be designated a fan-in block and any blocks connected to the power node can be designated fan-out blocks. Then, DC initialization and transient simulation for each time step can be performed for the circuit. During the transient simulation, any inter-relationship of the fan-out blocks can be determined and a sensitivity model can be calculated for each fan-out block. Because the power node is designated as an ideal power node, the results of the sensitivity model for each fan-out block can be added asynchronously to a total loadings of the power node. The total loadings can be loaded into a matrix, which is computed for the fan-in block, and a simulation waveform point can be output.</p> |
