gold Here is an eTCL script on to estimate reliability. For the push buttons, the recommended procedure is push testcase and fill frame, change first three entries a,b,c with always a>b, push solve, and then push report. Report allows copy and paste from console, but takes away from computer "efficiency".
In planning any software, there is a need to develop testcases to test the software. Always a>b.
Testcase 1. Testcase 2. Testcase 3.
