Mentor Graphics - HyperLynx

[onsimini]

Hello alls,

About impedance matching and resistor terminaison, how do you manage them and do you used tools like HyperLynx from mentor graphics ?

Thx.

I follow reference schematics. If needed, I only use series termination resistors (usually 22-33OHMs). I do not normally use any other kind of termination (ideally you should not need them).

Different terminations is possible to simulate also in Altium (however I am not sure how real the results are). For DDR simulations I usually use Hyperlynx (if the client has license).
