This reference has lots of information on simulating DDR5 and LPDDR5 interfaces with the HyperLynx DDRx Wizard.
https://docs.sw.siemens.com/en-US/doc/861057060/202301007.hl_ddr5_lpddr5_gd Design and verification of a DDR5 / LPDDR5 interface can be a daunting task. There exists a wealth of information scattered in many places, making it difficult to know what is necessary and important when simulating an interface. This guide will attempt to close the gap and provide information necessary to simulate a DDR5 /LPDDR5 interface in HyperLynx™software. Additionally, included at the end of the document is a list of additional resources such as Support Center, HyperLynx workshops, and relevant Knowledge Base articles.
