ASCENEXT
Product Details
Julin ASCENEXT is a dedicated, whole-board, batch Signal Integrity (SI) time-domain simulation platform focused on the PCB level.
It incorporates a proprietary, self-developed Golden-level high-precision True-SPICE engine—TJSPICE—offering a complete batch simulation solution for everything from general signals and DDRx interfaces to multi-board cascading systems.
Leveraging its Golden-level simulation accuracy, ease of use, and highly efficient automated simulation capabilities, ASCENEXT empowers engineers to perform Design of Experiments (DOE) validation and optimization prior to manufacturing. This significantly reduces physical prototype iterations and effectively compresses R&D costs and development cycles.
