ok ,, from cadence , after u run the simulations and the output u need is in the graph , in the tool bar , press edit --> select all .. then on the bar below that , there is a button called table .. press it then save .. ( this will give u the exact graph u can see but in a tablular form in an excel sheet )
Then all u have to do in the Matlab , press File then Import Data .. then browse and select ur excel sheet .. There u go , u will find ur table in the variables .. hope this helps
