Hi Everyone,

can i simulate two nets simultaneously in line sim ?

Suppose i want to simulate DQ0 & DQS0 simultaneously, can i do it?

**An idea (unverified):**take the min/max values of the driver's output,

subtract the min/max values of the receiver's input switching threshold,

take the minimum of both,

subtract a 50% safety margin and you get a crosstalk tolerance value.

**Example:**Driver output LOW max. voltage = 0.2 V

Driver output HIGH min. voltage = 1.1 V

Receiver input LOW threshold = 0.4 V

Receiver input HIGH threshold = 0.85 V

LOW margin = 0.4 V - 0.2 V = 0.2 V

HIGH margin = 1.1 V - 0.85 V = 0.25 V

0.2 V is the minimum of both, so:

0.2 V - 50% = 0.1 V =

**100 mV crosstalk tolerance.**Comments welcome!

Hi Sandeep,

You can start a second instance of HyperLynx and start a second simulation therein.

(But maybe that's not what you mean)
