Seeking for Help in PSS Analysis

Xuijing
Hi i am a beginner in using Cadence. I am designing a LNA and i meet problem when come to PSS analysis. My pss analysis could not run and terminated. I am clueless and have no idea. Could anyone please help? Here i attached my schematic and the simulation log pictures.

  • Hi Shawn, thank you for paying attention on my problems and your suggestions. My frf1 is 5GHz and frf2 is 5.04GHz. I tried to run transient analysis but the simulation keep running nonstop and never come to the end. My inductors value are as follow:

    L8=3nH

    L13=0.5nH

    L10=2.8nH

    L2=3nH

    May i know what are the possibilities that caused the PSS analysis unable to converge? I am a totally beginner in using Cadence hence my knowledge is very limited. Hopefully you can kindly share your knowledge and experience here. Thank you.( i have attached my transient analysis simulation log)
