The pinout on even the most mundane parts such as a BSS123 is not
standard. At first the layouter didn't think so until it did go wrong.
Data*** said 3-1-2, his CAD said 1-3-2. Bzzzzt. What blew me away was
that they even changed it when Siemens became Infineon. IOW there is no
standard.


I don't have that problem... at least not very often... it's rare that
I do a discrete project as I am at the moment.


Well, I can only suggest to watch out. I had several cases where there
was a discrepancy between the schematic of the layouter and his own
layout program. Both being from the same vendor :-(

Where it went wrong the most: SOT23 FETs (mostly n-channel ones), dual
diodes in SOT23, FETs in DPAK. So now I visually check every single type
after the layout.

That's why I compare MY netlist to the netlist generated by the layout
tool.
