Hi,

How to determine the capacitance of a logic block. eg; let's say i have 2 nand gates connected in a logic block, How will i estimate/determine the capacitance of that logic block manually? If anyone have idea of it and if possible provide it with figure.
 

checkout the library.lib file for finding the capcitance on the pins.
 

hi


u can have a look at the book "digital integrated circuits" by rabaey , chandrakasan:

in chapter 6 they show how to estimate the capacitance of logice gates in terms of minimum sized inverters...
