WEBENCH® Tools: Webench functionality with obsolete part (LMX2315/6)

Tool/software: WEBENCH® Design Tools

Team-

My customer has an older design that they want to do some analysis on the open loop gain and phase margin using different components, but their design uses the LMX2315/6 which an obsolete TI device. Is there any way to have Webench still function with these devices despite them having no web presence on TI.com or being available for purchase any longer?

Thanks,

Alec
