What does the transient noise tab in the analyses window of spectre means and
what were the values should be given for noise max. ,noise min and bins if my oscillator
is working at 450MHzand running for 150ns.
Thanks in advance.
Have you read the documentation?
In general I wouldn't use transient noise for an oscillator - you'd be better off using pss/pnoise or hb/hboise analyses. Again, see the documentation for more detail, or look in <MMSIMinstDir>/tools/spectre/examples/SpectreRF_workshop .
