The book "Parallel Sparse Direct Solver for Integrated Circuit Simulation" provides a comprehensive introduction to algorithmic methods and parallelization techniques for developing a parallel sparse direct solver specifically designed for integrated circuit simulation problems. The authors, Xiaoming Chen, Huazhong Yang, and Yu Wang, explain a complete workflow and detailed parallel algorithms of the sparse direct solver. Additionally, simple yet effective numerical techniques are presented to enhance performance. The techniques described for the sparse direct solver are applicable to any SPICE-like integrated circuit simulator and have proven to be powerful in practice. Readers will benefit from modern techniques in parallel integrated circuit simulation, particularly the latest methods for solving sparse matrices.
