With the rapid increase of the design scale and the continuous improvement of the design process complexity, especially the scale of parasitic devices in the post analog circuit brought by the complex FinFET technology, the traditional SPICE simulation tool has encountered unprecedented challenges in functional verification. Firstly, the simulation time is too long, and many designs have to run for several days or even weeks; secondly, the simulation capacity is huge, which has exceeded the processing capacity of traditional simulation tools; moreover, the number of PVT process angles is more and more, which can not be fully and accurately verified, which greatly increases the design risk.

The existing post simulation tools in the market can not meet the needs of the industry. On the one hand, the speed can not meet the requirements, and it takes weeks or even months for some post simulation circuits; on the other hand, the accuracy can not meet the requirements, because the post simulation tools may adopt more radical reduction technology to improve the performance, resulting in the simulation results can not be accepted; finally, it is not convenient for users to use and need to set different circuit types In order to get better speed and accuracy.

Empyrean Alps (accurate large capacity parallel spice) is a new generation of high-speed and high-precision parallel transistor level circuit simulation tool, which can break through the capacity and speed bottlenecks encountered in the verification of large-scale circuits under the premise of maintaining 100% spice accuracy. Alps can handle the design of tens of millions of components (especially for post analog circuits). It adopts unique intelligent matrix solver and parallel technology, which greatly improves the simulation speed. Compared with other commercial parallel spice simulators, Alps has a speedup of 3-8 times.
