The purpose of EDA is to develop and virtually validate new printed circuit board concepts to eliminates physical prototypes, and ensure compliance to functional standards.
0. Start with Concept
1. Technology Investigation: Verify that best technology in terms of performance is chosen before starting the actual layout phase.
2.Layout Import: Import layout with pecifications from technology investigation.
3. Design Rule Checker: Verify that layout rules to prevent SI, PI and EMCinterference are properly applied to printed circuit board
4. Signal Integrity: Predict the reliability of serial high-speed (PCIe,SATA, ….) and parallel data (DDRx) links.
5. Power Integrity: Simulate DC Drop and High Frequency Noise on power supply nets and optimize decoupling capacitors for impedance minimization.
6. Thermal Simulation: Verify that your device won’t exceed temperature range.
CST PCB Studio: For signal and power integrity analysis of PCBs.
