I used a string in a generic with the '&' operator (as shown in the
code fragment below), but it does not concatenate (ignores the part
after the &)

Do you know if concatenation is not allowed for generics?

entity mux is

generic (

PartNo : string := "12345" & "ABC"

);

port (

TxClk : in std_logic;

Etc...

Gives PartNo as "12345"

Probably depends on your synthesis tool.

I've used string concatenation in constants with any problems, but never
generics as far as I can recall...

I had defined it (also) in the test bench at the top level of the simulation

That tool is broken. Report the bug.
