TJSPICE

Product Overview

TJSPICE is a general-purpose circuit SPICE simulator that can be considered as the industrial accuracy standard. Based on the TrueSpice and analysis algorithm independently developed by Julin, TJSPICE can provide high precision and compatibility with golden standard.

TJSPICE supports all common circuits and devices from transistor level to system level, and can be widely applied in scenarios ranging from Foundry modeling and library building, transistor-level circuit simulation to board-level system signal integrity analysis. , TJSPICE supports the mainstream SPICE format and can be seamlessly integrated into the existing chip design and system design process.

Main Functions and Applications

Device model is the key of an excellent SPICE simulator. TJSPICE provides robust device model support ranging from classical device models to new advanced ones. Benefiting from state of the art device model implementation algorithms, TJSPICE shows golden accuracy compared to current industry golden SPICE tool while with higher efficiency. Device models ranging from the Compact Modeling Council (CMC) standardized models (BSIM, PSP, HiSIM, etc.) on the latest technology nodes to models designed for specified applications have been proven.

For SI/PI applications, TJSPICE provides sound support of S parameter, transmission line/VIA, and latest version (IBIS 7.0) of IBIS/IBIS-AMI model. By this TJSPICE can be used in chip/package/PCB SI/PI analysis in pre-layout stage and in post-layout sign-off stage as a golden spice simulator.

Transient, linear, and statistical analyses are available in TJSPICE for users to do all kinds of what-if analysis and design check in different application fields. All simulation results can be displayed and post-processed by Julin’s waveform viewing tool.

TJSPICE’s statistical analysis allows designers to do both traditional single-ended IO (DDR, etc.) SI analysis and SERDES differential SI analysis. Statistical analysis is especially important in BER estimation for SERDES interfaces which needs billions of bits simulation. This is beyond traditional true-spice simulation’s limit.
