Not aware of a single document that will show that for all platforms. Best way is "show interface hardware-mappings". "Unit" and "Slice" are the main points of reference (unit == ASIC instance, slice == pipeline). 

E.g., 93180yc-ex:
leaf1# sh int hard
Legends:
       SMod  - Source Mod. 0 is N/A
       Unit  - Unit on which port resides. N/A for port channels
       HPort - Hardware Port Number or Hardware Trunk Id:
       HName - Hardware port name. None means N/A
       FPort - Fabric facing port number. 255 means N/A
       NPort - Front panel port number
       VPort - Virtual Port Number. -1 means N/A
       Slice - Slice Number. N/A for BCM systems
       SPort - Port Number wrt Slice. N/A for BCM systems
       SrcId - Source Id Number. N/A for BCM systems
       MacIdx - Mac index. N/A for BCM systems
       MacSubPort - Mac sub port. N/A for BCM systems

Subject: [c-nsp] N9K ASIC port grouping

Dear C-NSP community,

My google is failing to locate the exact information about N9K ASIC port grouping.

I found some docs and presentations here and there but not a single clear table for all models (mostly 9200 and 9300 series).

If someone could be nice enough to point in the right direction, I would really appreciate it.

Best regards.
