HSPICE

HSPICE is a commercial circuit simulator developed by Synopsys. It is a SPICE-compatible engine widely used for the simulation of analog, mixed-signal, and radio-frequency circuits. Known for its emphasis on accuracy and robust convergence, HSPICE has long been a staple in semiconductor design verification and characterization.

Analyses supported by HSPICE include DC operating point, transient, small-signal AC, noise, distortion, and sensitivity analyses. It can perform Monte Carlo and corner analyses to evaluate process, voltage, and temperature variations. The tool provides behavioral modeling, hierarchical subcircuits, and a broad set of device models, including MOSFET BSIM family, BJT, MESFET, and diode models.

Features and capabilities encompass detailed parasitic modeling and post-layout simulation, support for large device counts, and scripting for automated runs. HSPICE maintains compatibility with SPICE netlists and can exchange models with other EDA tools, supporting mixed-signal simulations within common design workflows and environments.

Usage and applications center on IC design flows for circuit characterization, verification, and reliability assessments. It is widely used in RF and analog design, power electronics, and mixed-signal systems, and is also employed in academic settings as a benchmark for SPICE accuracy and modeling fidelity.
