6 Threads found on edaboard.com: Ibm 130nm cmrf8sf
I am using ibm 130nm cmrf8sf PDK. I made a simple inverter and performed DRC, LVS, PEX with Calibre. The DRC and LVS work well, but there is a PEX error shown as follows:
"error: Could not find pin mapping for terminal sub of cell (cmrf8sf devicepad symbol). It will remain unconnected."
I don't quite (...)

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:
*ERROR* Device 'nfet(Generic)' on Schematic is unbound to any Layout device.
Any ideas on how to solve this?

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.

by "assura extraction" I assume you're using RCX. The kit no longer supports RCX, use Cadence QRC. You can find the supported tools here (IC613 is also supported although its not listed):

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

i use cmrf8sf 130nm, it is a very good kit. the structure gets tricky once updates are installed and you should be careful about the paths defined in .cdsinit, .cdsenv and cds.lib to ensure you are using the latest version of the kit.
