Star-HSPICE Characteristics

Simulation in Stable, Transient, Frequency Domain Modes

Simulation from DC to Microwave frequencies Greater than 100GHz

Number of Elements Only Limited by Computer Memory

Using from AvanWaves to Waveforms Display and Analysis

Circuits and Models Optimization


Simulation Process

Using from a Text Editor Program to Generating an Input File. This File consist Information about Circuit and Called NETLIST. This File Type is “.SP”

HSPICE.EXE Running to Circuit Simulation and Output Data Generating

AvanWaves Running to Output Graphs Display
