MLIN simulation question in RFDE
Apr 27^th, 2010, 8:51am

Hi Guys
I am simulating a filter using transmission line. I use MLIN for the transmission line in ADS. The software reports the following errors.
Can anyone suggest how to fix it? It seems to complain I did not give the model for substrate which I specified as Msub1. Do I need to give a seperate substrate file? If so, can anyone give me a sample Msub1 file.
I will greatly appreciate it.

Warning detected by hpeesofsim during netlist flattening.
Cannot find substrate `MSub1'.

I can't find out any design issue in your post.

Your questions are no more than very easy issues regarding usage of very specific vendor's tool.

Hi pancho
Thanks for your comments, I did find there is a component in adsLib called MSUB. However, can you specify how I can solve the problem? Any suggestions? Most of the adsLib components work fine so far except Mlin.
I put a MSUB into the schematics and it still reported the same error.
Thank you

I am sorry, it might be dummy question. But can you tell me how to place substrate definition component in schematic? The closest component I found in adsLib is MSUB. Please give details, thank you so much!

There are "MLIN", "TLIN", "Term", "analogLib/cap", "analogLib/res" and "analogLib/gnd". Again see http://www.designers-guide.org/Forum/YaBB.pl?num=1265012932 From your all previous posts, I think you can't understand ADS and RFDE at all.

yes, I mixed the components from analogLib and adsLib. Thank you for your reply. I will have a look on the post.
Why do you think I do not understand RFDE at all.
I think RFDE is a software to use ADS simulator and library. And at the same, use cadence to layout.
Are there more deep understanding on RFDE?
Thank you again

Mixture of "analogLib" and "adsLib" is no problem.

It is might be true I did not know ADS too much.
I modified the schematics, now it reported new errors.
Here is the error.
Any suggestions?

There is a substrate definition component in this schematic(http://www.designers-guide.org/Forum/Attachments/Screenshot-3_001.png).

Did you understand there is no one in previous your schemtic ?

�Now I understood there was no substrate in my previous post. I did not realize I need to put it in the schematics. First time to have this question.
thank you!
I did not find netlist file in my directory. I attached the totally directory file.
thank you
