资料介绍
Offset Voltage
· the Vos measurement is simple.
· Assuring that it represents something useful is Not.
· Vos for Balanced Diff Amps ideally is 0.
· Monte Carlo analysis in Spectre?
-does both Process and Mismatch parameter randomization
-No tie to Layout, or identification of "pairs"
-Requires fancy Model work to make "useful"
-Matched Pair Pcel & inline Circuits would help
· Corners Analysis with special models could be easier.
· Parametric Analysis can work with variables for vt and w & L shifts.
Investment in TB pays off with Scripts
· Almost Any Interactive Setup has Script Equivalent
· Each Tool can create a script from its current state.
-duplicates setup, simulations and measurements
-Artist, Parameter Analyzer, Corners Tool, Monte Carlo, Optimizer
-Plots, and Printouts can be created in a file.
· For 1 Cellthis aids in re-veritying performance after ECO and with Layout Parasitics.
· Also Enables soft IP re-use. Cel can be re-optimized to different specs, or process.
