corner expression to compute averages over temperature and supply variations in maestro

Shlok Vaibhav
Shlok Vaibhav 7 months ago

I want to create an expression which can give me average of a spec over corners where temperature has a certain value, for example, i am using two supplies, two temperatures (-40, 125) and 3 processes so total 12 corners, but i want two averages over 6 corners each given by the specific temperatures -40 and 125, by changing evaltype, i am able to create expressions that give me average over all corners as shown below but not over temperatures, I can create two separate tests with only temperature different but wanted to know how to do in single test, I assume there is something i can write after the ? in the expression that can do it?

    Please look at slide 32 onwards in What’s New in Virtuoso IC6.1.8 ISR24 and ICADVM20.1 ISR24 (you would need to be using that version or later) - the Measure Across Any capability allows you to do this.
