I saw it on the ARM video linked below.  My apologies for mis-ascribing
it.  It's part of their ARM Education Media program.  I have never used
Xilinx FPGAs.  Only Lattice and .

As in the 6502 simulation, with the ability to then graph the outputs in
the standard form, but I want to see things by value, by logical port,
by time, by change.

I have seen a couple in the Quartus tool and Lattice has something
that is GUI-based, but they are not quite on the same level of use as
the one show in the ARM video.

I may be reading more into the ARM video presentation than actually
exists as I have had a vision in my mind of what I want Logician to
look like, and may be projecting that vision onto the Xilinx tools.
