Feature 4 – SIwave DCIR and XYZ solver Performance Improvement
What's new: Major performance upgrades to the SIwave DCIR and the XYZ solver through deep code
optimization of siwave_ng and sidirect_solver
Advantages:
• Confident signoff on larger, more complex boards that previously took many hours but now can practically
be solved in a fraction of the time
• 4X to 10X faster results faster design cycles
• Lower compute cost with no sacrifice in accuracy, since performance gain comes from solver optimization
