SIDesigner

Product Details

Julin SIDesigner is an Electronic Design Automation (EDA) platform for modern high-speed digital systems.

Leveraging its core Golden-accuracy SPICE engine, it provides precise, one-stop SI/PI analysis and timing sign-off for integrated systems spanning the chip, package, and board levels.

Key Highlights

Full-Link System Coordination (Co-Simulation)

· Integrates chip-package-board interconnect effects to achieve closed-loop validation of signal, power, and timing at the system level.

Sign-off Grade Simulation Accuracy

· The built-in TJSPICE Golden-accuracy simulation engine achieves industry-recognized sign-off standards in both True-SPICE time-domain simulation and Channel simulation, demonstrating outstanding convergence and stability.

Pre-Layout Exploration and Optimization

· Supports rapid "what-if" analysis of topology, termination, and power networks during the pre-layout stage, mitigating SI/PI risks at the source and minimizing iterative cycles.

Heterogeneous Modeling and Co-Simulation

· Integrates with third-party 3D Full-Wave Solvers to enable circuit-electromagnetic co-simulation, allowing for the precise handling of complex interconnects and package structures.

Comprehensive High-Speed Interface Validation

· Provides dedicated simulation workflows for parallel interfaces (e.g., DDR/HBM/UCIE) and SerDes interfaces (e.g., PCIe/MPI/USB/XSR), meeting the high-bandwidth requirements of 5G/AI and similar scenarios.

Unified Platform and Workflow Integration

· Completes the entire workflow—from AC analysis and transient simulation to system-level parameter validation—within a single environment. It supports customization and integration with other design tools, boosting efficiency and data consistency.

Advantages and Value Proposition

Sign-off Grade Accuracy

SIDesigner's simulation accuracy is highly consistent with industry Golden Standard tools, with errors generally below 1%. This performance is particularly outstanding in the simulation of complex parallel buses like DDR and HBM. This provides engineers with a reliable basis for sign-off, ensuring first-pass design success.
Comprehensiveness: Full-Link High-Speed Interface Coverage from Chip to Board

The platform has been validated for comprehensive support of both parallel interfaces (e.g., DDR/HBM) and high-speed SerDes interfaces (e.g., PCIe/XSR). This demonstrates the capability to address the design and validation needs of mainstream and cutting-edge interfaces in the 5G/AI era.
Powerful Core: Unified Simulation Engine Balancing Efficiency and Accuracy

Within a single platform, SIDesigner seamlessly integrates Transient Simulation (for accurate time-domain waveforms in DDR/HBM), Statistical Simulation (for fast channel analysis in PCIe), and Bit-by-Bit Analysis (for complex modulated signals like XSR PAM4). This provides users with the optimal solution for various stages of the design process.
Core Value: Enabling Precise Decisions and Accelerating Time-to-Market

By providing trustworthy simulation data, SIDesigner helps engineers accurately predict system performance and optimize design bottlenecks early in the design phase. This leads to a substantial reduction in expensive hardware iterations, significantly shortening the R&D cycle, and lowering development costs and risks.
