I am trying to calculate the average propagation time carry_TP from carry_TPHL and carry_TPLH which I already got the expression from the calculator tool and works well. Now how do I make the third output expression for carry_TP = (carry_TPHL+carrt_TPLH)/2? What I have tried (shown in image) isn't working for me. I am using the cadence icfb version 5.

In the screenshot, it looks like you're summing carry_TPLH twice?

If the problem you've got is format related, I know in Virtuoso IC6 and upwards that you can do (carry_TPLH + carry_TPHL)/2, but alternatively you could try the calcVal function:

(calcVal("carry_TPLH" "your_test") + calcVal("carry_TPHL" "your_test"))/2
