Dears, Can anyone tell me how to convert S-parameter cable model in touchstone format to Spice format so that I can simulate in Hspice?
Hello everybody! Does anyone experience to make coaxial cable model (not straight line model. It must be curved line) by using HFSS? If someone has make it can you explain a little bit how you was make it and what materials you was use in this model.

Hi all, please tell me how to model cat5 cable in 100/1000M ethernet PHY transmitter simulation , I am pullzed in this for several months. IEEE 802.3 only gives 10M cable model , but it doesnot fit for 100/1000M. Thank you in advance!
Dear Krashkealoha If I have a touchstone 8-port cable model, how can I do the simulations in Hspice for transient analysis and also the S-parameters, can u give me an example?
If I am using BSIM model for simulation. Do I need to key parameter like AD, AS, PD and PS. Does BSIM model account for these parameters in the simulation?

Hello, I want to simulate o dc booster in spice. I would like to make a model simulation of Lbreak. I try values from 1u to 1m but I'd like to have results after a period of time. As it is known a dc booster gives results after some mseconds. How could I make a model simulation of Lbreak after, for example, 10mseconds?? (...)
Gentlemen, I need your help. I'm trying to make a pv cell model to charge a capacitor in my simulation in Proteus ISIS. I have made model attached, but the current and voltage at the output are inverted (i.e. negative). I have searched the web for a functioning model or proper explanation with no success. (...)

Hi,all. I followed the method of kundert and constructed a pll time domain model to simulate the total phase noise.The model can work correctly,but when I extended it to sigma-delta fractional pll,the output phase noise seems unreasonable.The sigma-delta modulator is a MASH1-1-1 one.I wanted to see the output phase noise only from sigma-delta

I want to calculate the current flowing in the outer conductor of the Coaxial cable in case of mismatching at the load of the cable in HFSS. I have simulated the simple coaxial cable model in HFSS...Can anyone guide me how to measure the current flowing in the outer conductor of the Coaxial cable under (...)
Hi, I am simulating an IBIS model in HSPICE..can anyone give a small demo example code for doing the same?
Yes, it's a low capacitance (large D/d ratio), resistive wire coax cable. Exact simulation may be difficult, because the lossy line models of most simulators are representing the loss frequency characteristic (mainly set by skin effect losses) rather poor. I know the Aplac simulator as an exception, there may be others.
I think, the basic question is, if AWR has a suitable cable model and is using it in time domain simulation? Did you calculate the expectable pulse response by hand?
Hello ev'body, I'm using Pspice for circuit design, I have to insert a Coax model... I need these four attributes: R, C, L, G of RG-174/U Coax cable. So, R is resistance per length unit (Ω/m), so I found it using: R=(d/2)*(d/2)*π*ρ C is requested by my pro

hi, i build some code in spartan 3, but there is strange thing in "simulation model" simulation. chip is not responding on signals before there was 10 clocks. then work as was designed. does it need some "warm up" time? to warm up all cathodes in tranzistors? :))
Hi there, this question might be a little bit of topic under ASIC design tools - but I didn't found a better place - and methodologies fits at least a little bit ... Could someone guide me to some material that explains how "reduced matrix spice solvers" like HSim are working in principial and how/why they gain their speed advantage towards

Hey, I am desiging an 800MHz LNA. The spec for it its S11 and S22 <-10, NF<0.8 and Gain preferably as high as possible. Before biasing the network, i would able to get those results. After biasing it, i failed to achieve the goal that i want. Could anyone help me in this? I need it urgently. Thanks. Regards, Jun
Hi all Please help to check the attached schematic of Transmission line pulse generator and its corresponding waveforms at each node. S1 is a switch controlled by the voltage pulse “swctl” as shown in the picture, when swctl is 0V, S1 is open (huge resistance), when swctl is 1V, S1 is closed (zero resistance). I have 2 questions:
Hi, everyone. I want to design a PLL, and never have designed it before. Could you tell me what the procedure of pll design? Is it firstly caculate each blocks' spec, phase noise, bandwidth, Kvco and so on, then do each block design? Thanks you very much!
Hi I was working with Linecal utility in ADS to design a coaxial cable model. Generally when you select the component it shows a component illustration window with a nice diagram showing all the parameters on the sketch. For some reason I am not getting to see the picture inside the linecal. This is for any of the component I try to work in Line

Hi, I am stuck on a part of my design. I would be greatful for any help/info given. I am trying to design a circuit in Proteus from datasheet EL5170 by Intersil page 10 Figure.22 single supply twisted pair. The chip is not in the ISIS library so I have designed it my self. I designed the chip by looking at the datasheet and assigned a packa
