Model QA

1
Model QA

• Model QA spec reviewed at phone meeting by QA
  sub-committee, then updated and released
• Distributed on web site for review by whole CMC
  membership
• Now pending approval at 2Q06 CMC meeting
• QA specification
• directory structure
• test specification definition
• code that runs the tests and compares test
  results
• Makefile
• perl code modules
• structure for simulator dependent routines,
  examples for ADS, Hspice, Spectre, Spice3f5
• example test set up and results for BSIM3v3

How Variants are Tested
normal V1i V1x, I1i-I(V1i) V2i
V2x, I2x-I(V2x) reverse polarity V1i-V1x, I1i
I(V1i) V2i-V2x, I2x I(V2x) terminal flip
V1i V2x, I1i-I(V2i) V2i V1x, I2x-I(V1x)
m-factor V1i V1x, I1i-I(V1i)/m V2i V2x,
I2x-I(V2x)/m shrink and scale set in netlist,
instance parameters changed

Status

• Noise simulation routines need to be added
• in progress for noise currents only
• noise correlation in the future
• Plotting?
• would be xmgrace or gnuplot based
• Simulation routines for other simulators
• plan to set up repository on the CMC web site
• Evaluate/improve automated results comparison
  code
• Start to use it
• PSP
• update R2 tests
• will be used for R3
