How to access the Transmission Line Calculator in Allegro X APD

Have you ever thought of a handy utility to specify all necessary transmission line parameters to decide upon the stackup?   

Starting SPB 23.1, a handy feature Transmission Line Calculator, is built into Allegro X Advanced Package Designer (Allegro X APD). This feature will require either an SiP Layout license or can be accessed through SiP Layout Bundle. 

From the Analyze dropdown menu in the 23.1 Allegro X APD toolbar, you can choose Transmission Line Calculator. 

You can use this calculator to help decide constraints and stackup for laminate-based PCB or Packages. You can calculate the correct stackup material and width/spacing to meet any requirements that may be later entered in a constraint. This is truly a calculated number and not a true field solver. 

The different types of calculations that the Transmission Line Calculator can provide are Microstrip, Embedded microstrip, Stripline, CPW (Coplanar), FGCPW (frequency-dependent Coplanar), Asymmetric stripline, Coupled microstrip (Differential Pair), Coupled stripline (Differential Pair), and Dual striplines. 

This feature is important for customers relying on fabricators/spreadsheets to provide this information or need to test a quick spacing/width as per the impedance value.
