RoadMap

Exportfiles:

• Upgrade Mira export file creation to take into account the case where several conditions are present. (Pending for Q to act)
• Mira: clean the table to remove bad unit before working with it. Will make code more readable.
• Ace TCR/deg files should be robust with regard of first line (iteration=...)
• NBTI exportfile to script.
• Rewrite for loops in the functions in order to enhance readability.

Model:

EM:

• Create a function that estimate the lifetime of the device. par: Scale, Ea, n, A, DeviceID, ConditionTable. Make it stand alone if user want to use it to check something. And add a call in BlackModelization (optional parameter). Could be used to estimate quickly time for a new experiment.

TDDB

• Test TDDB modelization when several area are provided.
• Compare datacruncher results with amsRel for TDDB.

Common:

• Robust modelisation: fit 1 followed by a study on outliners leading to a second fit (Cook's distance). see nlrob (robustbase)
• Implement hierachical models (mixed effect models) to check if they can be useful for self heating interference.
• Force fit option: avoid fitting again if the parameters are available
• Implement Kaplan-Meier and Exponential Greenwood Confidence Intervals
• Look into J.G. Stotvig codes. fitdistr is failing when censored samples are provided. Take advantage of know probability.
• Student's t-test function in order to analyze populations (eg: impact of lenght, or tool or wafer)
• Ficher's F-test to add to previous function.
• Copy the structure file locally (dimension of EM structures) and make comparison with time stamps. Would allow working without network.
• Find a way to store model in a file and directly call them. Avoid hard coding the models in the functions. Avoid redundancy (error prone). Ex: Black and TDDB lifetime.
• plyr strategie (split apply combine) on data with multiple structures inside the table?
• Use ldply to read a list of file instead of for loops.
• Create a function to compare experiments (by conditions, by wafer, by lot...)
• Create a function to save an exportfile corrected by a lifetime factor (useful to merge several wafer in 1 lot.)

Chart:

• Enhance legend presentation to include:
  • MTTF, Number of samples + number of censored samples<-- Create a table for this like in Minitab
  • Model parameters <- addressed with annotate + clipping off (2nd table)
  • Minimum 3 decades per charts
  • Revert renaming CreateGraph function.
  • Create new function for axis setting definition: deg scale or proba scale / linear or log scale

GUI:

• Create a small GUI to select the analysis to be performed
• Add an update function to the GUI in order to update the package.
• Add a close after analysis check box.
