how to confirm the crosstalking nets?

[terry_cn]

i am doing the signal integrity simulation now , and must do crosstalking between nets first.
but i met the trouble that i cannt confirm which nets would easily occur it ?
so anyone could do me the favour?

Try using Synopsys PrimeTime?

i use cadence allegro SI

i think this problem does nothing with tool
thanks for your reply

Hi,
it depends on the tools capacity. if u r using Cadence SoC Encounter or Cadence Nanoroute, tool will detect the crosstalk violation and repair it and if u want see violations using violation browser.

thank you first

Cadence SoC Encounter or Cadence Nanoroute ?
are they tools for IC?

i just do circuit PCB's simulation

eda software , such as signal storm, can report victim net and aggressor net.
you first set up a threshold of coupled capacitance, then fix victim net by upsizing cell or double spacing , or routing in different layer.

hi johnz

do u mean i should use some assistent tools to check nets ,except allegro tool ?

Hi terry,
crosstalk analysis I mentioned is in ASIC design.
For crosstalk analysis of PCB , plz go to the forum of pcb design.
