Find a list of floating gates in schematic

pham777

Hi,

I wonder if there is a skill code to find hierarchily a list of transistors which have its gate

1) not connected to power/ground

2) and not connected to other devices(transistors, R,L,C)

I am using cadence IC615.

Thanks a lot,

HP

    This is also something that can be done with a FastSPICE simulator, such as XPS or UltraSim. See "spectre -h static_highz" for more details, and also there's the "dyn_floatdcpath" check which is available in APS (so not a FastSPICE engine) as well as XPS which performs a "Dynamic Floating Node Induced DC Leakage Path Check".

    There's a RAK (Rapid Adoption Kit) for "Static and Dynamic Checks" available here.

    Andrew.
