[From an e-mail dated 8 Dec 2011]
I ran into a bug a while ago where it appeared that the auto-routing
algorithm hung and I ended up killing the app, but couldn't reproduce
it. Yesterday I found a repeatable case so I thought I'd send it to you.
o Open the attached "wire_bug.circ", select all, and drag the "Y"
output right 1 space.
o Note that the upper input to the AND gate that generates "hold" is
o Select only the "Y" output and drag right one space.
o The program shows "Computing connections..." and appears to be in a
compute intensive loop (Java gets 100% CPU and Windows messages are not
being processed). After about 15 seconds, it gets done, but the moved
output is disconnected.
This circuit was generated by the Combinatorial Analysis application.
You can open "wire_bug.circ" and analyze and regenerate the circuit and
get the same result.
