Hello all.
I have two lateral pnp transistors contained within one well. They are diode connected (i.e. the base and collectors are connected together). When I run ASSURA DRC I get the following error:
2 bad_n_well_welltap_multconn_erc
and the two base contacts of the lat 2 transistors are highlighted.
I understand that Assura is telling me there are two contacts to one n-well but I do not see why this is is a problem since the base contacts are at the same potential (they are connected together and held at ground).
N.B that the substrate contacts of the lateral pnp transistors are outside the n-well.
Also does anyone have a list of the common ERC errors and what they mean?
Thanks for reading!
