Reg-impedance,constraint setting(90 ohms)

[karthiksmartone]

Hi Friends,


what is impedance,how to calculate impedance?how to match 90 ohm impedance?how to set 90 ohm impedance in constraint setting...please explain me friends..... if any one give very practical means its very use full to me guys....


thanks in advance.....

hi karthi,
setup-->cross section-->select the single impedance and Differential mode impedance.change the dielectric thickness and trace width impedance will vary.for micro strip and strip line impedance formula is used check it in google you can find
