I am not an expert on ibm 130nm but it sounds like an antenna vioaltion of M3 to a diode not connected to the substrate.
For nets connected to NW contact, where the NW net is not connected to a substrate contact defined by ((RX over BP) not over (NW or JD or PI))
This means for a metal to NWell contact (using P+ SD) that is not also connected

Hi i am designing an LNA on ibm 130nm and cannot decide which capacitor,inductor or resistor to take for my LNA .I have to work for 2.4 GHz.Ifsomebody knows it.Please help me for it.
Also tell me what is meant if its written that this capacitor is availble withBEOL metallizatin only.

Hi there, in my circuit I'm using inductors of ibm-130nm (cmos8rf) with M1 ground-plane. When instantiating inductors we can select internal connection o external connection. For what I understand, internal connection should be used when one of the terminals is connected to an AC ground potential, which is my case. I supposed that the layout of suc

For the design of a CML based XOR gate, at low frequency it works fine.
As I increase the frequency ~1GHz, the o/p has a delayed rise time. What parameters do I need to change to get the accurate waveforms?

I am doing a layout of a simple common-centroid differential pair with multipliers and fingers using ibm 130nm cmrf8sf. DRC runs fine. But i get malformed device error:

Regarding the mapping of transistors, you need to understand both technologies well. Sometimes you can't map cells 1:1 , but it depends also on the properties of the source cell, which target cell to choose.
Migrating schematics in that particular path (ibm -> TSMC) you may face trouble with different symbols, symbol orientation, different number o

I am simulating some inverter output stage using ibm 130nm pdk.

It seems incorrect.
Can anyone tell me what should be the correct way to do the sweeping ?
