X2Y Mount Tab
The X2Y Mount tab, shown in Figure 1–11 , is used to calculate the capacitor mounting
inductance seen by the X2Y decoupling capacitor.
User inputs in this tab are similar to those in the Cap Mount tab except that the VOE
or VOS options are not required. If you plan to use a different footprint capacitor
other than those available in the tool, you can skip using this tab and directly enter the
capacitor parasitics and capacitor mounting inductance in the Library tab (replacing
the preset value with your own data in the X2Y Decoupling Cap section). As with the
other tabs, you have can save the changes made to the tab, restore the changes, and
restore the tab back to the default settings.
