Is it possible to enter RLGC data of a transmission line in ADS ?

[DoYouLinux]

Hi all,

I am trying to simulate a transmission line. I have a set for RLGC data (at some frequency points) and want to use this data in a transmission line. How can I do this in ADS ? In Cadence, I can select "RLGC model" in "mtline" component. I don't know how to do the same thing in ADS. Please suggest .....

Thank you in advance,

DYL

Hi!

Yea, it seems not straightforward. "Google for RLCG file" . It seems some component data can be entered through a file which can be included. If its one frequency, you might just draw it with RLCG components (20 repititions per wavelength)

Good luck

Hi Darkcrusher,

Thank you for your answer. It seems that I need to use TLine_Multilayer to operate with RLGC file in ADS.

Use W-Element as HSPICE compatibility ability of Agilent ADSsim.

Hi pancho_hideboo,

Thank you very much for the information. However, as I searched from internet, I could not find how to define RLGCfile (static, tabular_list, tabular_file) to be used with the W_Element in ADS. I just have a set of RLGC data extracted from an EM simulator (the format is: freq, R, L, G, C). I don't know that how should I re-arrange the RLGC data I have to be compatible with those ADS need.

Thank you very much in advance,

It seems you don't know other simulators than Cadence Spectre and Agilent ADSsim.

See "HSPICE Signal Integrity User Guide".

"W-element of HSPICE" is a defacto standard transmission line model for SPICE type Transient simulator.

"analogLib/mtline for Cadence Spectre" is no more than an imitation of HSPICE W-element.
Actually "analogLib/mtline for Cadence Spectre" has been developed for aiming at HSPICE W-element.
So setting parameters of "analogLib/mtline for Cadence Spectre" very resemble them for HSPICE W-element.

Both Agilent ADSsim and GoldenGate understand Cadence Spectre Netlist directly,
but they don't support "analogLib/mtline for Cadence Spectre".

so you can never expect any helpful reply other than Cadence Tool there.

Thank you very much, pancho_hideboo,

I am studying about the information you gave to me.
