Dear sidt, [quote userid="496331" url="~/cadence_technology_forums/f/rf-design/47321/interstage-matching-in-cadence-virtuoso"] read something about 'sprobe' in cadence forums. I think I need to use that block. But unfortunately, I could not find it in my analogLib. Has it been added recently? Or am I missing something? (I'm using IC617) [/quote] If I understand your question, I believe this document will help understand its use in finding an interstage impedance for use in matching. support.cadence.com/.../ArticleAttachmentPortal Have you examined this? The note indicates the following: " The sprobe was introduced in IC617 ISR15 , ICADV12.3 ISR15 and Spectre 16.1 ISR8." Hence, if your installation is earlier than ISR15, it will not be in the analogLib. Shawn
