These need to be re-done in a way that is more
tolerant of the inherent instability/noise in
the simulated circuits (or more ideally, changed
to test a particular thing that can be more
well-defined rather than just simulating a circuit
and seeing if the numbers come out a certain way)
(cherry picked from commit e427099cff04128bef7594445d8d4d97590b91ff)
We are really only testing that `Rload1` works,
and the original testcase is unstable on some platforms.
(cherry picked from commit 2ecf1ac23f940ecab5039efa1964524255452164)
strcmp returns 0 if strings are the same but compareIbisWord returns
True (1).
Adds an IBIS simulation QA test case to catch this in the future
