Simple Reliability Slot Calculator Example

Simple Reliability Slot Calculator Example

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.

In planning any software, there is a need to develop testcases to test the software. Always r(1)>r(2x)&r(3x) for a valid answer.
