Hi everyone,
I can pass the DRC and LVS. But when I run PEX, an error occurs: Error MAC3 on line 2498 of $TECHDIR/LVS/Include/<tech>.lvs_extract.cal - duplicate DMACRO definition name: SUBC_PROPERTIES.
Can anyone tell me what I should do? Thank in advanced
Re: Problem on post layout simulation
Hi everyone,
Thank AlexL.
I followed AlexL's instruction and I got another error: Error MAC3 on line xx of $TECHDIR/LVS/Include/<tech>.lvs_extract.cal - duplicate DMACRO definition name.
How can I fix this error? Thank you so much.
Thank Sam,
I think you may be right. But I want to ask one more question. How can I fix it? When I trie to create my own library (my_lib) with "Attach to an existing techfile" option, the CIW displayed this warning. It means that I did not go to run QRC step.
Thank samiran_dam,
I follow your instruction. However, the problem is still there.
I use Cadence IC 615, and the "Enable CellView Check" option is un-checked as default.
Can anyone help me to calculate the transfer function of Right Left Handed Transmission Line? Do I need to terminat 50 ohm resistor at the input (source) and output (load)?
Thank in advanced.
Hello everyone,
I want to calculate the transconductance gm of a MOSFET in ADS (Advanced Design System). I used equation gm = diff(I_drain,VGS) but it didn't work.
ADS displayed the error: While evaluating "gm": left operand: ee_boolparameter value required
Can anyone help me?
I test with ideal inductor and the result from equations are right. The problem is in the s2p file. I also check the HFSS structure. I change some variable and now I have a good inductor. Thank you very much. I really appreciate your advice.
I'm sorry. Because I'm in a hurry. I read your suggestion but I don't know what I should do. I worried that I cannot ask you too much and you don't have time to answer my foolish questions. I'm ever so sorry. I greatly appreciate your kindness.

Hi, I am a newbie in RFIC design.
I want to design a spiral inductor on chip. Follow some instruction on internet:
First, I draw it in HFSS, simulate and extract the S-parameter to s2p file. After that, I use ADS to calculate the inductance:
I don't know why it's wrong. The inductance look like...
Re: converting y-matrix to s-matrix ads
Thank volker_meuhlhaus. My schematic for simulation is included in attachment. I followed some instructions, but result is wrong.
Can anyone help me? Thank so much.
Re: converting y-matrix to s-matrix ads
Thank for your advice. However, I have not known how to convert S-parameters to Y-parameters. Can you show more detail?
