Glucose Meter

We were tasked with performing detailed Software testing and analysis of a safety-critical medical diagnostic device. As we investigated the code we discovered:

    • Unbounded recursion through 8 levels of calls in an error detection / reporting routine
    • Critical data which could be corrupted when Interrupt Service Routines (ISRs) ran at specific relative times
    • Execution times for critical ISRs which were much longer than the designers intended
    • Dozens of other potential problems of varying severity

We developed and deployed a complete analysis process which found latent defects that their existing processes could not find.

As a result, our client awarded us with Best Value of all 3rd Party Contributors.
