which book is good for info on Fanout (wire loading, delay modeling, Fanout threshold,) drivers, victim / aggressor(Dominant aggressor, aggressor / driver, P:N widths) Wire Capacitance(Model Capacitors ) , Keeper Circuits, Power P Chains, Interconnect, etc.., in a single book.
Hi all Plz tell me what is victime net and aggressor net.... What they are checking for Celtic crosstalk analysis tool.... Plz tell me clearly Thanks in advance DIN
TWF contains timing window & slew data . Tools find the earliest & latest arrival times for each victim net & aggressor net.The range of switching times from earliest to latest arrival,defines a timing window for victim net & defines another timing timing window for aggressor net.Crosstal effects occur when (...)
Hi, While doing STA with OCV and xtalk ON, using PrimeTime SI, is there any way by means of which I can control timing windows. Basically what I am asking is, when we turn ON both OCV and Xtalk we usually see lot of timing violations (because of pessimism introduced). To remove pessimism we can apply some filters like filtering

It is important to use a Pulse witha rise time the same as or close to what your circuit will see, of course 1 aggressor 1 victim measurement will not show you what to expect witha large number of signals switching simultaneously or close to simultaneous, however, you may find in this situation the return path may be the main crosstalk generating o
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.
Above high noise: When the victim net is static high and the aggressor net switches from 0 to 1, there will be a noise bump in the victim net. The magnituge of this voltage bump will be greater than VDD. Below low noise: This occurs when the victim net is static low and the aggressor net switches from (...)
hello, In an affected net, what will u work on first , aggressor or victim?????????????? pls reply soon thanks, Prasad
i would normally put my gnd on the bottom side..Vcc on top side with ample area distibution..i wouldn't call it planes..you could also stitch your gnd on the bottom to the top..mainly for protecting victim lines or isolating the aggressor lines..again, it all depends on your app..
SI can effect the delay throught a net by either increasing its delay (effecting setup time) or decreasing its delay (effecting hold time). Imagine a net with a weak driver (victim net) surrounded by nets with stronger drivers (aggressor nets). If all the nets switch from low to high around the same time, the aggressor nets can help pull (...)
Glitches on a victim net are caused by switching of nearby aggressor net(s) and the coupling capacitance between vitim and aggressors. This can lead to incorrect data to be captured by a flop and thus a functional error. Delay noise is similar but the victim net is also switching. This can cause the (...)
In asic terminology .. cross talk between aggressor net and victim net causes Glitch and some delay is also induced hence to avoid glitch ..double spacing is maintained for clock net Shiv
reflection, termination, transmission-line impedance continuity, etc... All are same dude, Reflection is cross talk- Signal strength flowing in one wire (aggressor) will affect the other (victim), maens a crosstlak refelects Termination- Is electromigration, due to more cureent flowing than requried the wire may br
IF agressor and victim are moving in the same direction how do we get setup violation?
Hi, iwpia50s is correct. All of you know that the victim is the weaker net then your aggressor. So if you insert the buffer in the victim net your victim net will become little stronger, then you know..... Prithivi.
Crosstalk is the unintended signal distortion due to coupling capacitance between two neighbouring nets. Due to decreasing process nodes to cope with the requirment of routing, additional metal layers are being used. The width of these additonal metal layers is decreasing rapidly and the height of these additonal metal layers is increasing.
In order to get answer you need to know the emission level for your aggressor equipment and what is the coupling to the victim microstrip line. Finding these values usually more difficult than make right design and eliminate EMI.
Hi, It depends on slew(transition) of aggressor net and coupling capacitance between aggressor and victim net. Regards,
Hi All, I have too many noise violations in my design. I tried fixing them by increasing driver strength, wherever I could size-up the cell. This fixed some noise violations, but also caused NEW noise violations as the former victim is now aggressor to other nets. So I'm back to square one and trying to decide what sub-set of noise nets
We know that breaking the victim net by adding a buffer will remove the cross-talk violations. What is the basic concept behind this?
Hi, I know we can upsize the victim net so that coupling is reduced. If by upsizing say the victim becomes the agressor ? My Question is what is the best method to deal with crosstalk in this scenario ? Note: There is no space to shield the aggressor net. It would be great if u could elaborate and provide some good materials (...)
Thank You...Plz can u name some victim signals, normally occurs in Analog layout... diff pair inputs,diff pair outputs ,biasing signals
Hello all! As a part of project, I'm doing PCI Express simulations where topology looks like: PCB1 (Intel)>---->connectors&cable>------>PCB2--->CEM--->Gfx card (TI). The graphics card uses PCI Express generation 1, single lane (x1), so that what we will be using. I'm doing this simulations in HyperLynx 8.1.1. I have some question I h
You can begin with the concepts of "aggressor" and "victim". Every conductor in your assembly with a time-varying voltage or current launches electric or magnetic fields, and electromagnetic radiation. Every conductor is also an antenna and any attached device a potential receiver / amplifier. Now many of these are minuscule in scale, sensitivi
Hi; As i know in basics; Simply set apart aggressor and victim lines/planes. Place groun lines between them Try to use different layers May be some experts here can do better commends.
hi all , I came to know that during PT SI crosstalk analysis calculation , The first step is to consider infinite arrival window to nets , i.e nets can switch any time . I have few doubts 1) Is this infinite arrival window considered for aggressor/victim or both ? 2) Why is it done ? 3) wont it make calculation more pessimistic ? Please
Hello, I have a question about coupling capacitance.... Will the capacitance be formed between any metal layers ?? For example can it be formed between similar metal layers M1-M1. I understand it can be formed between different metal layers M1-M2, M2-M3 etc... Also can the capacitance formed between M1-M5 M2-M6 like that
victim. If you have guard traces around a net that are not connected to anything, you actually jus t make a bad antenna that will not do much. You want to make that guard as low impedance as possible so that radiated energy that hits is quickly funneled away.!
