Ah yes... some instrumentation (below) demonstrated it. Thanks!

They're both right - you've got a race between your fill calculation and
the inner read/display loop. for your code to work, the '@(ci)' timing

I hit a case with Icarus synthesis involving embedded
multiplication expressions inside concatenations. Outside
a concat, the multiplier is synthesized to the correct
precision. However, inside a concat, the multiplier
precision is doubled. Also with this case, I find a couple

This variant does the same thing in both simulators...

When I simulate the following module with NC I get the expected result, when I
simulate with Icarus 0.8.1 the simulator goes into an infinite zero-time loop.
What I expect to see is that after the initial block puts four entries into
