Embrace High-Speed Design
Is your PCB design high-speed? Even using standard components like DDR3, DDR4 or DDR5 SDRAMs means following high-speed PCB design guidelines. Let’s route some DDR3 memory.
Let’s constrain and route some DDR3 memory
In Product Settings, we choose a high-speed license and then we’re ready to constrain our critical differential pairs and we’ll assign a differential-pair rule stack to the differential clock. The rule stack for the DDR3 clock yields a differential impedance of 100 Ohm.
