This is the printout (the only data I have) from a GAL first used in 2003. (Not exactly a FPGA, but the closest section I could think it might belong in)
In the Programmed Logic section, I think that the exclamation mark signifies inversion, like it does in C.
I’m puzzled by the next section (which the printer spread over two pages).
The exclamation marks appear on all the pins that are outputs. I suspect that the no longer refer to an inversion of the logic, but may signify that they are outputs?
Can anyone confirm.? The second page appears first, I can’t seem to get the iPad to put them in the correct order.
